马来酰肼残留在卷烟燃烧过程中的转移行为

Transfer Behavior of Maleic Hydrazide Residue in Cigarette During Smoking

摘要: 通过对烟支进行加标,研究了马来酰肼在卷烟燃烧过程中的转移行为,并采用热裂解技术研究了马来酰肼的裂解规律。结果表明:①马来酰肼整体转移率较低,其中向主流烟气转移率在1.41%~3.67%之间,向侧流烟气转移率在0.24%~0.86%之间,向烟蒂转移率在1.19%~1.87%之间,烟灰中无转移。②马来酰肼的热裂解产物主要是CO₂。

Abstract: The transfer behavior of maleic hydrazide (MH) in cigarette during smoking was studied by adding internal standard. The pyrolysis mechanism of MH was studied with pyrolysis technology. The results showed that:1) The transfer rate of MH into mainstream cigarette smoke was from 1.41% to 3.67%, into sidestream cigarette smoke was from 0.24% to 0.86%, and into cigarette butts was from 1.19% to 1.87%; no MH was found in ash. 2) The main pyrolysate of MH was carbon dioxide.
