三氟乙酸(76-05-1)生产方法和用途

用途:

一,该品是许多有机化合物的良好溶剂,与二硫化碳合用,可溶解蛋白质。也是有机反应的优良溶剂。可获得在一般有机溶剂中难以获得的结果。三氟乙酸用于合成含氟化合物、杀虫剂和染料。是酯化反应和缩合反应的催化剂;羟基和氨基的保护剂,用于糖和多肽的合成。还用作选矿剂。

二,三氟乙酸是重要的有机合成试剂,由它可以合成各种含氟化合物、杀虫剂和染料。三氟乙酸也是酯化反应和缩合反应的催化剂;还可作为羟基和氨基的保护剂,用于糖和多肽的合成。

三,三氟乙酸 (TFA) 是一种化学实验室常用的有机酸,由于羧基的邻位碳上连有3个比较强的电负性基团氟原子,使羧酸根的亲核性大为降低,因此三氟乙酸常用来作溶剂,来研究反应的溶剂效应。三氟乙酸的沸点比较低,挥发性好,并且酸性强,因此它可以催化很多酸催化的化学反应,并且后处理比较容易,可以通过减压蒸馏而除去。此外,三氟乙酸可以参与氧化反应、还原反应、重排反应和去保护基团等。

四,用作试验试剂、溶剂、催化剂及用于有机合成。

生产方法:

一,以2,3-二氯六氟-2-丁烯氧化制取;

二,以氟为催化剂对2,3-二氯六氟-2-丁烯进行氧化以制取之;

三,由3,3,3-三氟丙烯经高锰酸钾氧化、或由三氯乙腈与氟化氢反应生成三氟乙腈继而水解、或将乙酸(或乙酸酐)进行电化学氟化,都可制得三氟乙酸。精制方法:在氮气流下蒸馏精制。或加五氧化二磷回流后蒸馏。进一步纯化可分步结晶后再蒸馏。

四,三氟乙酸可由3,3,3,-三氟丙烯经高锰酸钾氧化制得;或由三氯乙腈与氟化氢反应,首先生成三氟乙腈,继而水解制得;也可用乙酸或乙酸酐进行电化学氟化制得。
