| 摘 要： | 为了解保润剂对卷烟感官质量和有害性的影响,采用正交试验方案研究了热解温度、氮气流量和氧气浓度对丙三醇和丙二醇裂解生成的8种挥发性羰基化合物的影响。结果表明:①氮气流量是丙三醇和丙二醇裂解生成甲醛的主要影响因素,除丙二醇裂解生成丙烯醛和巴豆醛外,其他7种挥发性羰基化合物的主要影响因素都是裂解温度;②相同条件下丙三醇的甲醛、丙烯醛和巴豆醛产生量显著高于丙二醇,800℃下丙二醇裂解产生的丙酮、丙醛和甲乙酮量显著高于丙三醇;③丙二醇和丙三醇热裂解产物甲醛、乙醛、丙烯醛、丙醛和丙酮产生量的不同可能是其分子中的C-O和C-C键能的差别造成的;④就危害性和感官质量而言,丙二醇作卷烟保润剂的效果应好于丙三醇。

| Abstract: | The effects of temperature,flow rate of N2,concentration of O2 on the formation of 8 volatile carbonyl compounds from pyrolysis of glycerol and 1,2-propylene glycol were studied with orthogonal experiments to investigate the influence of the humectants on sensory quality and toxicity of cigarette smoke.The results showed that:1)The flow rate of N2 was a main factor affecting the formation of formaldehyde,and the temperature was a primary factor affecting that of the other carbonyl compounds except for acrol... |
