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 re-alkanes in the core material, filter and mainstream smoke particulate matter of heated tobacco products was established. The transfer behavior of re-alkanes in heated tobacco products was studied by measuring the content, release and mouth-to-mouth release of re-alkanes in heated tobacco products. The results showed that: 1) The particle phase transfer rates of 13 re-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 re-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 re-alkanes ranged from 0. 28 to 0. 44. The coefficient of variation of the puff-by-puff release of tridecane ( boiling point 235°C) and tetradecane ( boiling point 254 °C) was small, and the puff-by-puff release stability was good. Based on the evaluation data of the retention rate of re-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 of additives suitable for heated tobacco products was proposed to be about 250 °C.
