Abstract
A process for preparing glycol esters such as ethylene glycol diacetate which comprises contacting a monoolefin such as ethylene with an organic monocarboxylic acid such as acetic acid containing a palladous salt and either a nitrate or a nitrite.
Claims15
A process for preparing glycol esters from a monoolefin selected from alpha-monoolefinic aliphatic hydrocarbons having up to 8 carbon atoms and styrene, which consists essentially of contacting said monoolefin with a solution of a palladous salt and at least one compound selected from alkali metal nitrates and nitrites in an organic acid selected from alkanoic acids having not more than 7 carbon atoms and benzoic acid at a temperature ranging from 20.degree. to 150.degree. C.
A process for selectively preparing glycol monoesters which consists essentially of contacting a monoolefin selected from alpha-monoolefinic aliphatic hydrocarbons having up to 8 carbon atoms and styrene with a solution of a palladous salt and at least one compound selected from alkali metal nitrates and nitrites in an organic acid selected from alkanoic acids having not more than 7 carbon atoms and benzoic acid at a temperature ranging from 20.degree. to 80.degree. C.
A process for selectively preparing glycol diesters which consists essentially of contacting a monoolefin selected from alpha-monoolefinic aliphatic hydrocarbons having up to 8 carbon atoms and styrene, with a solution of a palladous salt and at least one compound selected from alkali metal nitrates and nitrites in an organic acid selected from alkanoic acids having not more than 7 carbon atoms and benzoic acid at a temperature ranging from 80.degree. to 150.degree. C.
