WARTERLY REPORT
JANUARY - MARCH 1968
INTRODUCTION
In view of the importance attached to the design
and development of
bonded low density granular filters, which has
been a major effort during
the last quarter, some other projects have
necessarily been somewhat
delayed. The success achieved in this area of work
led to visits to the
Establishment by Dr. J.G. Esterle of Brown and
Williamson Tobacco
Corporation, Louis~ille, and Dr. V.C. Runeckles,
Mr. L.A. Rowell,
Mr. S. Candlish and Mr. D. English of Imperial
Tobacco of Canada.Ltd.,
Montreal.
Work on filtration is now to be concentrated on
practical means of
incorporating water in filters.
'7 he oQzoperation between Marketing Dept.
Millbank, and R. & D.E.
hAs led to the establishment in Millbank of a
further Taste and Flavour
Working Par-ty, using the technique developed
within R. & D.E.
During the quarter, P. Curson attended the Junior
Management Course
at Chelwood. Dr. R.G. Hook's secondment to
Management Services Dept. was
made permanent.
At the end of the period under review, Mr. C.N.
Burnett retired after
nearly 7 years at R. & D.E. and a career covering
38 years with the B-A.T.
Group. The Establishment will miss his helpful
co-operation but is
fortunate in that Mr. A.W.G. Smeed will replace
him as Manufacturing Section C.
Head.

PROJECT 1000 RESEARCH INVESTIGATION WITH SHORT
TEF44 OBJECTIVES
1100 Tobacco Studies
(Miss C.W. Ayers) (1) The testing of analytical
procedures for TRC
using tobacco samples supplied by Carreras has
continued.
(S.R. Evelyn) (6) A report has been issued on the
compariscn of
burn rates of U.K. and Continental pipe tobaccos.
1200 Smoke Studies
(Miss C.W. Ayers) (1) The collaborative T.R.C.
test carried out in tne
(A.W. Cronshaw) I.T. Co. (Bristol) laboratories
has been completed.
Using identical experimental conditions, the
personnel
from the various companies showed that good
agree:-..en~
was obtained for the analysis of T.P.M., nicotine
alkaloids and water. The statistical analysis of
results has continued.
(2) No JANIJS samples were analysed tMs quarter.
(D.J. Wood) (3) The examination of further Belgian
cigarettes
(Miss C.W. Ayers) treated by the French process is
under way. This
(A.W. Cronshaw) exercise has been undertaken to
determine whe-Lher -.,-ends
suggested by the analytical results obtained with
--rE
first sample of treated Belgian cigarettes are
valid.

ANALYTICAL RESEARCH S=IES
Tobacco
(7) A report has been issued describing the use
and
limitations of the methylene blue test for blend
analysis.
Although the test may, in some cases, give an
indication
of the proportion of flue-cured tobacco in a
blend,
it cannot be recommended for routine use.
(8) The work on the re-appraisal of the methods
for
measuring total nicotine alkaloid content has been
started. She re-appraisal covers G.L.C. methods as
well as those of Willits, and Cundiff and
Markunas.
(9) Work comparing the various methods of defining
atmospheric moisture content has been completed.
(10) A report has been issued on the determination
of selenium in tobacco and cigarette paper.
Smoke
(6) The interpretation of the chart spectra, sent
by A.E.I., has been completed. However, no
progress
can be reported on the computer processing of the
spectra, since A.E.I. have been using the PDP-8
computer for their own internal projects.
(9) A first report has been issued on the mass
balance
of C-14 activity added to cigarettes. The
apparatus
and collection system works well and gives
recoveries
of the order of 85-95%.
(12) Further experiments with the artificial mouth
have indicated the amount of nicotine retained
from

the smoke of certain cigarettes, for example a
cigarette
with an efficient carbon filter, is less than
would
have. been predicted from the pH of the smoke.
Because
of these findings, the report will be delayed
until
next quarter.
(B.B. Chakraborty) (14) The G.L.C. equipment
essential for the analysis
(R.E. 7hornton) of aromatic polycyclic
hydrocarbons was delivered and
is being evaluated.
(?.A. Curson) (15) A report has been Issued on the
naming of gas
chromatography peaks by a computer.
(K.D. Kilburn) (16) Work on the three-dimensional
model of the
inter-relationships of smoke from various tobaccos
has continued and is almost complete. Uhe
coordinates
for the smoke samples are not dependent upon a
particular
mathematical convention provided it is applied
consistently.
NIss C.W. Ayers) (17) The automated method
developed for the determination
of ammonia in tobacco could not be used for smoke,
because
of interference from other amines and aldehydes.
Modifi-
cation of the automated method was unsatisfactory,
and
consequently G.L.C. methods are now being
investigated.
(P.A. Curson) (18) Work has started this quarter
on the examination of
the spline functions for calculating carbon
numbers.
However, it is delayed at present due to the
absence
of Mr. Curson on the Intermediate Management
Course at
Chelwood.

211,00 Other Materials
(C. Valentine) (1) The difficulties experienced in
the reduction of
myosm1ne have been overcome and the first stages
of the
synthesis of C14-nicotine are now under way.
(Miss C.W. Ayers) (2) The following ter-penes have
been purified (using
(Mrs. S.L. Vekris) the Perkin Elmer F21 Autoprep):
a-pinene, I imonene,
a-thujene, and p-cymene. Infra-red and mass
sp-~ctra
have been recorded.
24 co Development of Squipnent
(K.D. Kilburn) (1) A new type of wide-dynamic
range amplifier
manufactured by Infotronics Corporation, Texas,
has been
examined. It is suitable for use with G.L.C. flame
detectors operated with packed column systems, but
not capillary systems. Its use will reduce the
cost,
and simplify the general introduction of computer
processed G.L.C. to laboratories with access to a
medium-sized computer. A report has been issued.
PROJECT 3000 FACTORS AFFECTING S40KE GEENERATION
,31C0 The Effects of Tobacco
(A.A. CoLMins) (1) A report has been issued on the
fractionation of
soluble nitrogen compounds in tobaccos of
different type.
(3) Two further sugar/amino acid complexes have
been
synthesised. The effect on smoke aroma of adding
complexes of this sort to cigarettes is being
evaluated
by the Taste and Flavour Working Party.
(Miss C.W. Ayers) (7) A report has been issued
describing thework
carried out at R. & D.E. on the determination of
oxides
of nitrogen in smoke.

(H.F. Dymond) (8) The smoke from cigarettes made
from flue-cured
tobacco, Burley tobacco, and a 50 : 50 flue -cu
red/Burl ey
blend, has been examined by the G.L.C. scan
technique.
Approximately 80% of the peaks from the blend are
the
arithmetical sum of the contributions of the
constituent
tobaccos. The other peaks are being studied.
(Miss C.W. Ayers) (9) Various methods for the
determination of total
sulphur in smoke have been investigated. So far,
little
success can be reported; the work continues.
(A.R. Cousins) (10) Me polyphenol-nitrogen
fractions from flue-cured,
Burley and dark fermented tobaccos are being
studied
using Sephadex chromatography and an AutoAnalyser
which
continuously and simultaneously monitors for
phenolic
and Primary amino groups. Analysis of nitrogen in
sub-fractions obtained from these experiments has
confirmed earlier findings which were based on
separation of the sub-fractions using their
colour.
The Effects of Culture and ?rocess
(D.J. Wood) (4) The report has been issued on the
1966 Greenhouse
(R. Comber)
(Miss C.W. Ayers) Experiment.
(D.J. Wood) (5) Cigarettes have been manufactured
from tobacco
produced in the 1967 Greenhouse Experiment (Hicks
variety cultured with varying lo&ds of nitrogen).
Examination of tobacco and smoke composition has
corLnenced.
(6) Seed has been sown for a further greenhouse
experiment, the purpose of which is to Investigate
the
effect of nitrogen level on the leaf and smoke
composition
of a Burley variety. <ZD

3140 The Effects of Cigarette and Smoking
Parameters
(Miss C.W. Ayers) (1) The analysis of the data
obtained from the first
phase evaluation of the Louisville type free
smoking
machine has not been completed, and consequently
the
report will be delayed until next quarter. The
experimental evaluation continues and a study is
being
made of the effects of free smoking on such
componen-z as
hydrogen sulphide.
(2) The problems associated with obtaining
cigarettes
for the study of factors affecting the yields of
various smoke components appear to have been
solved.
Analytical work should start next quarter.
3160 The Effects of Transfer and Pyrolysis
Processes
(K.D. Kilburn) (2) The theoretical study of the
factors affecting the
accumulation of precursors in the coal has
continued,
and experimental tests have supported the
principal
conclusions. 7here are indications that the rate
of
mass transker within the heated tobacco strand is
an,
important factor in smoke production.
3150- 7he Effects of Additives
(J.D. Backhurst) (3) A report has been issued on
the analysis of the
smoke from a 13urley tobacco to which a series of
ameliarants had been added. In a second report on
-.he
effects of a treatment of Burley tobacco with
acet-".--
acid vapour, a conclusion reached from earlier
work
has been withdraifn. It had been claimed that the
vapour treatment caused a decrease In the delivery
of
U11.1

hydrogen cyanide. Further work has shown this
claim
to be invalid.
(R.E. Thornton) (5) The results from recent
experiments indicate that
the addition of magnesium chloride or sodium
chloride
to a cigarette leads to an increase in the
delivery of
benzpyrene.
(H.F.D. Dymond) (6) The smoke from Burley
cigarettes was compared
with the smoke from Burley cigarettes containing
added
proline deoxyfructose monomer, and containing
proline
deoxyfructose polymer, respectively. No
differences
could be found using,the G.L.C. scan technique.
The
monomer was pyrolysed in the injection block of
the
gas chromatograph, biit only a few small peaks
were
detected. Sucrose was pyrolysed under the same
conditions and gave large peaks. It has been
tenta-.ively
concluded that neither proline deoxyfructose nor
its
decomposition products are to be found in the
volatility
range (00-3500C) of compounds examined by the
G.L.C.
scan.
Unprogrammed
(R.E. Thornton) A report has been issued in which
the deliveries of
benzpyrene from some commercial cigarettes are
given.
'No observations are of interest: (i) The smoke
from
BASTOS BLEU cigarettes has a very low
concentration of
benzpyrene; (ii) There is an indication that the
higher the chloride content of a tobacco, the
higher
is the production of benzpyrene.

PROJECT 3200 THE PROPF-iTZES OF '1HE SMOKE AEROSOL
3210 Characterisation of,the Aerosol
(R.B. Richardson) (1) Further work on the analysis
of smoke particle
(K.D. Kilburn) size fractions from cigarettes, to
which hydrocarbons
have been added, has confirmed that considerable
losses
of the lower hydrocarbons occurs. The higher
hydrocarbons~
for which a good recovery is found, appear to be
present
at similar concentrations in each size fraction.
3220 Deposition of the Aerosol
(R.B. Richardson) (1) A third report has been
issued on the deposition
of smoke particles on fine wires, and no further
work
is planned at this time.
