为比较卷烟纸及其7种原料和助剂(针叶木浆、阔叶木浆、淀粉、瓜尔胶、羧甲基纤维素钠、柠檬酸钾、柠檬酸钠)的裂解产物之间的差异性和相关性,采用裂解气相色谱/质谱联用仪(Py-GC/MS),对木浆和麻浆卷烟纸及所含的7种原料和助剂,在含9%氧气的氮气氛围下,快速升温到900℃进行裂解,并对其裂解产物进行了对比分析。结果表明,卷烟纸裂解产物主要以酮和醇类化合物为主,分别占42%、18%左右,且麻浆卷烟纸裂解产物释放总量高于木浆卷烟纸;2种木浆(针叶木浆、阔叶木浆)原料裂解产物与卷烟纸裂解产物分布的规律相似,但木浆裂解产生的碳水化合物与卷烟纸裂解相差10倍,差异较大;淀粉和瓜尔胶裂解产物种类相似,其中淀粉的裂解产物中碳水化合物比例最大,约为42%;羧甲基纤维素钠中酮类物质产生量最多,所占比例达到53%;2种助燃剂柠檬酸钾和柠檬酸钠裂解产物中芳香烃生成量最高,达40%以上,其他原料裂解产物中芳香烃含量仅为4%～6%。
To compare the differences between cigarette paper and its pyrolysis products of seven raw materials and auxiliaries (softwood pulp, hardwood pulp, starch, guar gum, sodium carboxymethylcellulose, potassium citrate, sodium citrate) And pyrolysis gas chromatography / mass spectrometry (Py-GC / MS) were used to study the effects of different kinds of wood pulp and linen pulp paper and seven kinds of raw materials and auxiliaries in a nitrogen atmosphere containing 9% Rapid heating to 900 ℃ for cracking, and its cracking products were analyzed. The results showed that the major products of cigarette paper pyrolysis products were mainly ketones and alcohols, accounting for 42% and 18% respectively, and the total release amount of pyrolyzed cigarette paper was higher than that of wood pulp cigarette paper. Two kinds of wood pulp Pulp and hardwood pulp), the cracking products of raw materials and cigarette paper were similar, but the difference between the cracking rate of carbohydrates produced by wood pulp pyrolysis and cigarette paper was 10 times, and the types of pyrolysis products of starch and guar gum were similar The percentage of carbohydrate in starch cracking products is the largest, about 42%; the amount of ketones in sodium carboxymethyl cellulose is the most, accounting for 53%; two kinds of accelerant potassium citrate and sodium citrate cracking products Aromatic hydrocarbons generated the highest, reaching more than 40%, pyrolysis products of other raw materials aromatic content of only 4% to 6%.
