摘要:采用热失重分析仪及热裂解-气相色谱/质谱联用仪对自制茉莉微胶囊及微胶囊卷烟纸进行热失重和热裂解产物分析。结果表明,微胶囊在235℃以上发生主要质量损失,囊芯物质从壁材分解的孔洞中逐步释放出来,整个质量损失过程比较平缓,未出现突释;茉莉微胶囊卷烟纸热裂解产物以易挥发的小分子醛类、酮类化合物为主,随裂解温度的升高,其热裂解产物在600℃时增加明显,而在900℃时增幅不如空白卷烟纸。茉莉微胶囊卷烟纸在300℃时裂解产生具有茉莉特征的二氢茉莉酮酸甲酯,对卷烟烟气成分和感官质量产生一定的影响。
Abstract:The thermogravimetric and pyrolysis products of homemade microcapsules and cigarette paper containing microcapsule were analyzed by thermogravimetric analyzer and pyrolysis gas chromatography-mass spectrometry. The results showed that the main loss of microcapsule mass occurred above 235℃, the core material was gradually released from the holes where the wall material was decomposed, The whole process of mass loss was relatively smooth without sudden release; The pyrolysis products of cigarette paper containing jasmine microcapsule were mainly volatile small molecule aldehydes and ketones. With the increase of pyrolysis temperature, the products of pyrolysis increased obviously at 600℃, but the increase was not as high as the control at 900℃. Cigarette paper containing jasmine microcapsule pyrolysis at 300℃ produced methyl dihydrojasmonate with characteristics of jasmine, which created a certain impact on the composition and sensory quality of cigarette smoke.
