1.丁酸钠与氯化苄在水中加热回流反应，反应结束后，冷却分层、减压蒸馏得丁酸苄酯。C3H7COONa+C6H5CH2C1→C3H7COOCH2C6H5+NaCl由苯甲醇与丁酸在硫酸催化下加热酯化而得成品。C3H7COOH+C6H5CH2OH[H2SO4] →C3H7COOCH2C6H5+H2O | |
主要用于增塑剂，香料。用作香叶天竺葵、铃兰、玫瑰、金合欢、百合、茉莉、素馨等花香型香精及果实型香精的调和香料。丁酸苄酯是我国允许使用的食用香料，常用于调制奶酪、奶油、杏子、李子、椰子、桃子、香蕉、菠萝、草莓等香型食用香精和玫瑰、葡萄酒香精，用量按正常生产需要。一般在口香糖中310mg/kg；糖果 7mg/kg；烘烤食品中 9mg/kg；冷饮中 9mg/kg。也可用作香皂的香料。 |
