摘　　要：为研究钾盐的种类及质量分数对卷烟纸裂解产物的影响,采用热重法(TG)和分段裂解-气相色谱-质谱法(Py-GC/MS)分析了9种卷烟纸的热失重和热裂解行为。结果表明:①9种卷烟纸的热失重分为4个阶段,主要热失重阶段发生在162~612℃区间内。②随裂解温度升高,裂解产物数量进一步增加、种类变得复杂。两个主要裂解阶段对应的裂解产物分别为:350℃下主要以酮类、醛类、酸类、酯类和醇类化合物为主,550℃下主要以酮类、醛类、酸类、醇类和酚类化合物为主。③钾盐的种类和质量分数差异对第一阶段(50~350℃)裂解产物产生不同程度的影响,对第二阶段(350~550℃)裂解产物的影响不大。整体上,添加苹果酸氢钾、酒石酸钾和柠檬酸钾等卷烟纸助剂会产生较多对烟气吸味有利的成分,而添加磷酸钾和乙酸钾会使烟气中苯类和酚类化合物以及乙酸的释放量增加,可能不利于卷烟吸味。In order to study the influences of the types and contents(mass fraction)of potassium salts on the pyrolysis products of cigarette paper,thermogravimetric analysis(TG)and segmented pyrolysis-gas chromatography-mass spectrometry(Py-GC/MS)were used to analyze the thermal decomposition and pyrolysis behavior of nine cigarette paper samples.The results showed that:1)The thermal mass loss of the nine samples could be divided into four stages,and the major thermal mass loss stage occurred at 162-612℃.2)With the rise of pyrolysis temperature,the number and type of pyrolysis products increased.The dominant pyrolysis products at 350℃were ketones,aldehydes,acids,esters and alcohols,and those at 550℃were ketones,aldehydes,acids,alcohols and phenols.3)The differences in the type and contents of potassium salts influenced the pyrolysis products at the first stage(50-350℃)to different extents,and slightly affected the pyrolysis products at the second stage(350-550℃).Generally,the cigarette paper additives,such as potassium hydrogen malate,potassium tartrate and potassium citrate produced more pyrolysis components which were beneficial to smoking taste;while adding potassium phosphate and potassium acetate would increase the releases of benzene,phenolic compounds and acetic acid in smoke,which might not be conducive to smoking taste.
