摘　　要：为了解脂肪酸酸碱形态对脂肪酸卷烟主流烟气转移行为的影响,开展了8种脂肪酸及其对应钠盐的热解和卷烟添加实验,分析了脂肪酸及其钠盐热解产物和主流烟气转移率的差异,并考察了烟草基质pH对脂肪酸主流烟气转移率的影响。结果表明:(1)热解条件下脂肪酸以原型转移的比例大于90%,脂肪酸钠热解不产生脂肪酸。(2)脂肪酸和对应的脂肪酸钠有相近的主流烟气脂肪酸转移率。(3)脂肪酸主流烟气转移率与烟草基质pH相关,烟草基质pH值越低越有利于脂肪酸的烟气转移。To understand the influences of the acid-base forms of fatty acids on their transfer behavior to mainstream cigarette smoke,pyrolysis and cigarette addition experiments were conducted for eight fatty acids and their corresponding sodium salts.The differences in the pyrolyzates of fatty acids and their sodium salts and the transfer rates to mainstream cigarette smoke were compared,and the effects of tobacco matrix pH on the transfer rates of fatty acids to mainstream cigarette smoke were investigated.The results showed that:1)The transfer rates of these fatty acids in their original form were higher than 90%under pyrolysis conditions,and the pyrolysis of fatty acid sodium did not produce any fatty acids.2)The tested fatty acids and the coresponding fatty acid sodium had similar transfer rates(by fatty acids)to mainstream cigarette smoke.3)The transfer rates of the fatty acids to mainstream cigarette smoke were related to the tobacco matrix's pH,and the tobacco matrix with a lower pH was more conducive to the transfer of the fatty acids to mainstream cigarette smoke.
