| 摘 要： | 利用热重/差示扫描量热法和热裂解分析研究了空气氛围下典型电加热和炭加热新型卷烟烟草材料热行为。结果表明:①两种典型的加热不燃烧卷烟烟草材料的热失重都分为四个阶段,碳加热型卷烟A主失重阶段发生在133-270℃,电加热型卷烟B主失重阶段发生在232-347℃;②两种烟草材料在前两个阶段失重量均要明显高于传统卷烟,主要是相对高比例的料香及烟雾生成剂的使用及较高的含水量;③两种典型的烟草材料在350℃热裂解,主要检出物质均为甘油、丙二醇和烟碱,其他主要物质还有乙酸、酮、醛和长链烷烃。

| Abstract: | The thermogravimetry(TG) and pyrolysis behavior in tobacco materials of two typical heat-not-burn cigarettes,including charcoal heating cigarettes(A) and electric heating cigarettes(B),were investigated by TG/DSC and Py-GC/MS.Results showed that ① TG in tobacco materials of two typical heat-not-burn cigarettes could be divided into four stages. The main weight loss stage of A was 133-270℃ but that of B was 232-347℃. ② The weight loss of tobacco materials of two typical heat-not-burn cigarettes in the first and the second stage was significantly higher than that of conventional cigarettes as there were relatively high proportion of flavor component, smoke generator and high water content. ③ The pyrolysis reaction of two typical tobacco materials were performed by Py-GC/MS at 350℃. The main detection substances were glycerol, propylene glycol and nicotine, as well as acetic acid, ketones, aldehydes, and longchain alkanes. |
