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/MS1、H 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。
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.
