摘要
Abstract
Phenethyl alcohol microcapsules were prepared by complex coagulation method with phenethyl alcohol as core material as well as gelatin and carboxyl methyl cellulose as wall materials. The microcapsule embedding rate achieves 92%. Effects of temperature and time on thermal releasing behavior of the phenethyl alcohol microcapsules as well as their storing stability on cigarette paper were examined. Results show that the phenethyl alcohol microcapsules can adhere on the paper fibers,and basically maintain no change at 120℃ for 10 min;so it can satisfy the main technological requirement for the cigarette paper. Basically,the core material of the microcapsules can volatilize completely at 180 ℃ for 40 min;while after storing under close and room temperature for 60 d,the retention rate of micro-capsulated phenethyl alcohol reaches 65%. It shows that the storing stability of the microcapsules is good.关键词
