Abstract

1365351 Vinyl acetate HALCON INTERNATIONAL Inc 21 Oct 1971 [22 Oct 1970] 49017/71 Heading C2C Vinyl acetate is prepared by the vapour phase pyrolysis of ethylene glycol diacetate. The feedstock is passed at a mass velocity of at least 200 lbs./hr./sq. foot of pyrolysis zone cross-sectional area. A temperature of 435‹ to 560‹ C. with a residence time of between 0À1 and 200 seconds is used. The ethylene glycol diacetate is prepared by esterification or by the reaction of ethylene, oxygen and acetic acid in the presence of halogen in the presence of a metal cation such as tellurum, manganese, copper, cobalt or chromium. Catalysts such as activated alumina, vanadia, molybdena, magnesia, alkaline earth pyrophosphates, zinc oxide and cobalt molybdate may be present during the pyrolysis. By-product acetic acid and acetone can be separated and acetic acid may be recycled to the diacetate preparation.
