| Abstract:In order to compare the difference and correlation of the pyrolysates of cigarette paper and its seven raw materials (softwood pulp, hardwood pulp, starch, guar gum, sodium carboxyl methyl cellulose, potassium citrate and sodium citrate), they were analyzed by pyrolysis gas chromatography-mass spectrometry (Py-GC/MS) in 9% O2 atmosphere and rapidly heating to 900℃. Results showed that: ①The pyrolysis products of cigarette paper were mainly ketones and esters, which accounted for 42% and 18% respectively, and the total amount of the pyrolysis products of the cigarette paper made from hemp pulp was higher than that of the wood pulp cigarette paper. ②The distribution of pyrolysis products of the two kinds of raw materials (softwood pulp and hardwood pulp) and cigarette paper was similar, but carbohydrates in the pyrolysis products of wood pulp were 10 times more than the pyrolysates of cigarette paper. ③The compositions of pyrolysates of starch and guar gum were similar, however there was higher proportion of carbohydrates in the pyrolysate of starch, about 42%. ④The proportion of ketones in the pyrolysate of sodium carboxyl methyl cellulose reached the maximum amount 53%. ⑤Aromatic hydrocarbon amounts were up to 40% in the pyrolysate of the two combustion adjuvants, only 4%~6% was found for other raw materials. |
