苯乙酸癸酯的合成及其在卷烟中的应用

Synthesis of Decyl Phenylacetate and its Application in Cigarette

摘要: 以一水合硫酸氢钠作催化剂,苯乙酸和正癸醇为原料合成了苯乙酸癸酯,考察了浓硫酸、对甲苯磺酸、硫酸氢钠作催化剂对酯化率的影响,采用GC/MS、¹H NMR、FTIR、折光率和相对密度对合成产物进行了结构表征,并用合成产物进行卷烟加香试验。结果显示:①以硫酸氢钠作催化剂时,反应的酯化率最高;②合成产物为目标物,纯度95.34%;③合成产物可明显提高卷烟烟气的香气质、透发性和劲头。

Abstract: Decyl phenylacetate was synthesized from phenylacetic acid and 1-decanol with sodium bisulfate as a catalyst.The effects of catalysts(sulfuric acid,p-toluenesulfonic acid and sodium bisulfate) on the esterification ratio were investigated.The composed product was characterized with GC/MS,¹H NMR and FTIR spectroscopies and applied in cigarette as a flavorant.The result showed that the esterification ratio was the highest when sodium bisulfate monohydrate as a catalyst,the product contained decyl phenylacetate up to 95.34%,and the aroma quality,volatility and impact of cigarette smoke were improved by the product.
