Temperature programmed desorption (TPD) technique was applied to measure TPD curves of β-phenethyl alcohol on five types of porous materials, and desorption activation energy of phenethyl alcohol was estimated. Effects of pore structure and surface properties of these porous materials on desorption activation energy of phenyl ethyl alcohol were also discussed. Results showed that: (1) Desorption activation energy (kJ/mol) of β-phenethyl alcohol on porous materials was in the following order: silica gel B(46.90 kJ/mol)

A method for simultaneously determining NO3 - and NO2 - in tobacco casing and flavors was developed based on ion chromatography(IC) and oscillation extraction. NO3 - and NO2 - in casing and flavors were dealt with oscillation extraction by utilizing water and dichloromethane. They were purified through membrane (0.22 μm) with column flow rate of 1 mL/min. and radient elution was performed. The samples were separated on an Ion Pac AS 11 column and detected with an electrical conductivity detector. Results showed that: (1) Limits of detection of NO3 - and NO2 - were between 0.010 and 0.006 μg/mL,with recovery rate ranging from 90.6% to 95.4% and RSDs from 3.42% to 4.61%, and linear range of 0.06 to 6.0 μg/mL and 0.02 to 2.0 μg/mL, respectively. (2) NO3 - and NO2 - in 15 tobacco casing and flavor samples were detected with detection rate of 53.3% and 40.0%. The method was proved to be applicable in determining NO3 - and NO2 - in tobacco casing and flavors as timesaving, accurate and simple to process.

In order to improve cigarette ash packing effect, various additives were used in the experiment. Single-factor analysis method was used as an analytical tool for analyzing all factors affecting the cigarette ash packing effect. The result showed that, additive P01 will lead to a better cigarette ash packing effect except a little gray of the ash color. Film-forming additives will be of benefit to the size of cigarette ash. Additive K01 combined with G01 or M01 has a better effect on cigarette ash packing.
