摘要: 为了解香料在加热卷烟中的热解特性,以12种醛酮类单体香料为研究对象,采用非等温热重法(TG)、差示扫描量热法(DSC)以及Coats-Redfern法和Šatava-Šesták法2种动力学分析方法对其熔融行为和热解行为进行分析。结果表明:(1)12种醛酮类单体香料的热重微分(DTG)曲线均表现出1个明显的失重峰,在其对应的DSC曲线上均表现出明显的吸热现象;(2)12种醛酮类单体香料均能在300℃前完成热解;(3)基于Coats-Redfern法和Šatava-Šesták法的分析结果显示,三维扩散模型D3可以较好地描述12种醛酮类香料的热解反应机制,12种醛酮类香料热解过程的活化能在89.51~236.99 kJ/mol,指前因子(A)在2.07×108~2.02×1023min-1,其中胡椒醛、邻甲氧基肉桂醛、乙基香兰素、甲基环戊烯醇酮和山楂花酮熔融过程的活化能在239.07~412.24 kJ/mol,lgA 在24.66~30.54;(4)对12种醛酮类香料的热解特性进行聚类分析发现,在平方欧式距离为10时聚为3类。综上,12种醛酮类香料的热解特性具有较大差异,但均能在加热卷烟的加热温度下完成热解。

Abstract: In order to understand the pyrolysis characteristics of flavors in heated cigarettes,with twelve aldehydes and ketones as the research objects,non⁃isothermal thermogravimetry(TG),differential scanning calorimetry(DSC)and two kinetic analysis methods(Coats⁃Redfern method and Šatava⁃Šesták method)were used to analyze their melting behavior and pyrolysis behavior. The results showed that:(1)TheDTG curves of twelve aldehyde and ketone monomer flavors all showed an obvious weight loss,and the corresponding DSC curves showed obvious endothermic phenomenon.(2)Twelve aldehyde and ketone monomer fragrances could complete pyrolysis before 300℃.(3) Coats⁃Redfern and Šatava⁃Šesták method analysis showed that the three⁃dimensional diffusion model(D3)could well describe the pyrolysis reaction mechanism of twelve aldehyde and ketone fragrances. The activation energy of the pyrolysis process of the twelve aldehyde and ketone fragrances was between 89.51 and 236.99 kJ/mol,which meant the prefactor(A)was between 2.07×108and2.02×1023min-1.The activation energy of the melting process of piperonal,o⁃methoxycinnamaldehyde,ethyl vanillin,methylcyclopentenolone and hawthorn ketone was between 239.07 and 412.24 kJ/mol,and lgA between 24.66 and 30.54;(4)Cluster analysis was carried out on the pyrolysis characteristics of twelve aldehyde and ketone flavors,and it was found that when the square euclidean distance was 10,they were clustered into three categories.In conclusion,the pyrolysis characteristics of 12 aldehydes and ketones were different,but all of them could complete pyrolysis at the heating temperature of heated cigarette.
