  • FEMA:2781
  • 方法一:γ壬内酯天然存在于番茄、朗姆酒、桃、大麦中,但工业上由丙二酸与庚醛为原料制得。 在500mL烧瓶中加入70g三乙胺和52g(0.5mo1)丙二酸,缓缓搅拌使其溶解,在40~50℃下在30min内滴加57g(0.5mo1)新蒸馏过的庚醛。然后在75~85℃下继续搅拌反应1h,直至不再有CO2气体放出。冷却后加入180mL20%的盐酸,静置分层,水层用50mL苯萃取2次。合并苯萃取液和有机层,水洗至中性后用无水硫酸钠干燥。先常压蒸馏回收苯,减压蒸馏,收集130~135℃(666.5Pa)馏分即为壬烯酸,折射率n D 20 1.446~1.447,产率约75%。 将32.2g壬烯酸(0.2mol)和4g HY型分子筛置于250mL烧瓶中,在170℃下搅拌反应3h,冷却后滤去分子筛,减压蒸馏,收集123~128℃(800Pa)馏分,即为γ-壬内酯。也可以80%硫酸作为内酯化剂,反应后用水洗涤,再用碳酸钠溶液中和、水洗,最后减压蒸馏得成品。
  • 用途一:用于调配食用香精、饲料香精等
  • Sigma Aldrich:104-61-0(sigmaaldrich)
  • TCI Shanghai:γ-戊基丁内酯 gamma-Nonanolactone,>;98.0%(GC)(104-61-0)
  • 方法二:1.由β,γ-壬烯酸在硫酸作用下内酯化制得。壬烯酸由庚醛与丙二酸反应制得。将80%的硫酸与壬烯酸一起搅拌,内酯化反应完成后,用水洗涤反应物,以油层用碳酸钠溶液中和,再经水洗,将油状物减压蒸馏即得γ-壬内酯。2.由7-羟基正壬酸与硫酸共热脱水而得。3.用铈、钒等高价醋酸盐或醋酸锰(+3)作氧化剂,由α-庚烯与醋酸反应而得
  • 用途三:本品用于配制果香型饮料香精,如椰子香精、苦杏仁香精等,还用作高级化妆品调香用的香料。也是一种有机合成的原料。
  • 具有强烈椰子香气溶于乙醇(1ml溶于5mL60%乙醇)、丙二醇、大多数非挥发性油和矿物油,几不溶于甘油,不溶于水。天然品存在于桃子、杏子、番茄、朗姆酒和炒大麦等中。
