摘　　要：按照正常生产条件,在芯材薄片生产环节加入13种正构烷烃类化合物制备加热卷烟,建立了适用于加热卷烟芯材、滤嘴和主流烟气粒相物中正构烷烃类化合物的GC-MS分析方法,通过测定加热卷烟中正构烷烃类化合物的含量、释放量和逐口释放量,研究了正构烷烃类化合物在加热卷烟中的转移行为。结果表明:1)13种正构烷烃类化合物主流烟气粒相转移率为0~53.5%、滤嘴截留率为12.6%~50.0%、烟支持留率为0.2%~35.4%、烟芯残留率为6.4%~29.3%、散失率为0.6%~81.5%;随着相对分子质量增大及沸点升高,正构烷烃类化合物主流烟气粒相物转移率、滤嘴截留率均呈先升高后降低趋势,烟芯残留率逐渐升高,烟支持留率先升高后趋于稳定;烟支持留率和滤嘴截留率与化合物沸点在一定范围内呈现较好的正相关关系。2)正构烷烃类化合物随抽吸口数增多,其逐口释放量呈先增大后减小趋势,但释放量最大值出现的口序不一致,化合物沸点越低,其释放量最大值出现的口序越早。3)正构烷烃类化合物逐口释放量的变异系数范围为0.28~0.44,十三烷(沸点235℃)和十四烷(沸点254℃)的逐口释放量变异系数较小,逐口释放稳定性较好。综合正构烷烃类化合物在加热卷烟中的烟支持留率、主流烟气粒相物转移率、逐口释放稳定性等评价数据,提出了适用于加热卷烟的添加剂沸点范围为250℃左右的建议。According to the normal production conditions,13 kinds of n-alkanes were added to the core material sheet production process to prepare heated tobacco products,and a GC-MS analysis method suitable for n-alkanes in the core material,filter and mainstream smoke particulate matter of heated tobacco products was established.The transfer behavior of n-alkanes in heated tobacco products was studied by measuring the content,release and mouth-to-mouth release of n-alkanes in heated tobacco products.The results showed that:1)The particle phase transfer rates of 13 n-alkanes in mainstream smoke were 0~53.5%,the filter interception rate was 12.6%~50.0%,the smoke support retention rate was 0.2%~35.4%,the smoke core residue rate was 6.4%~29.3%,and the loss rate was 0.6%~81.5%;With the increase of relative molecular mass and boiling point,the transfer rate of particulate matter and the interception rate of filter in mainstream smoke of n-alkane compounds increased first and then decreased,the residual rate of cigarette core increased gradually,and the retention rate of cigarette support increased first and then stabilized.The smoke retention rate and filter rejection rate showed a good positive correlation with the boiling point of the compound within a certain range.2)With the increase of the number of suction ports,the release amount of n-alkanes increased first and then decreased,but the order of the maximum release amount was inconsistent.The lower the boiling point of the compound,the earlier the order of the maximum release amount.3)The coefficient of variation of the puff-by-puff release of n-alkanes ranged from 0.28 to 0.44.The coefficient of variation of the puff-by-puff release of tridecane(boiling point 235℃)and tetradecane(boiling point 254℃)was small,and the puff-by-puff release stability was good.Based on the evaluation data of the retention rate of n-alkanes in heated tobacco products,the transfer rate of particulate matter in mainstream smoke,and the stability of puff-by-puff release,the boiling point range
