Abstract
Procedeu pentru obtinerea tricloracetonitrilului, care în scopul asigurarii unui randament marit de ordinul a 85...95% precum si a unei puritati îmbunatatite efectueaza clorurarea acetonitrilului cu un amestec de clor si oxigen la un raport molar clor : oxigen de 1,5 : ...2:1 si un raport molar clor: acetonitril de 3...4:1, la temperatura de 350...450 degree C, utilizînd drept catalizator halogenura de argint depusa pe piatra ponce.The process for obtaining trichloroacetonitrile, which in order to ensure an increased efficiency of 85 ... 95%, as well as improved purity, performs the acetonitrile chlorination with a mixture of chlorine and oxygen at a chlorine: oxygen ratio of 1.5: 1. 2: 1 and a chlorine: acetonitrile molar ratio of 3 ... 4: 1, at a temperature of 350 ... 450 ° C, using silver halide catalyst deposited on the pumice stone as the catalyst.
