CAS: 431-47-0
分子式: C3H3F3O2
分子量: 128.05
沸点: 43-43.5℃
熔点: -78-44℃
中文名称: 
三氟醋酸甲酯
甲基三氟乙酯
三氟乙酸甲酯
英文名称: 
Trifluoroacetic acid methyl ester
trifluoro-acetic acid methyl ester
trifluoro-acetic aci methyl ester
methyl trifluoroacetate
性质描述: 无色液体。沸点43-43.5℃,相对密度1.273(20/4℃),折光率1.2907,闪点-7℃。溶于乙醇、乙醚,不溶于水。
生产方法: 由三氟乙酸与甲醇酯化而得。将甲醇、三氟乙酸混合,添加浓硫酸,回流反应5h后进行高效分馏,收集50℃以前的馏分。再分馏一次,收集40-43℃馏分即为三氟乙酸甲酯。收率80%。
用途: 用于有机合成。

应用
Useful reagent for trifluoroacetylation of amines under mild conditions. In the presence of 1,1,3,3-Tetramethyl?-guanidine, has also been used for the N-acylation of amino acids. It is used as an intermediate in the synthesis of pharmaceutical and agricultural chemicals. The chemical reactions usually involve nucleophilic substitution of the ester and are useful for the preparation of trifluoroacylated compounds.

备注
Moisture sensitive. Store away from strong bases, water/moisture and oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition. Store under inert gas. Protect from humidity.
