This invention relates to a process for preparing ethylene glycol esters by intimately contacting a mixture of ethylene, bromine or chlorine (or a bromine or chlorine containing compound) and oxygen, in the presence of a carboxylic acid and a variable valent metal cation. It also relates to a process for preparing vinyl acetate from ethylene, by pyrolysis of ethylene glycol diacetate prepared as above noted, and to the preparation of ethylene glycol monoester as well as ethylene glycol by the hydrolysis of the ethylene glycol di-ester as prepared above. |
