- 3 - Ethoxy acrylonitrile and 3, 3 - diethyl dimethoxypropionitrile is treated mixture of synthetic method
-
The invention belongs to the field of medicinal chemistry, in particular to medicinal chemistry of the in the field of organic synthesis, more in particular to 3 - ethoxy acrylonitrile and 3, 3 - diethyl dimethoxypropionitrile is treated mixture of synthetic method. The method uses acetonitrile with a ester alcohol under the action of the alkali metal salt, to obtain the intermediate compound II, then this compound II and then under the action of the phase transfer catalyst, with the sulfuric acid b b obtained by the target mixture compound I, namely 3 - ethoxy acrylonitrile and 3, 3 - diethyl dimethoxypropionitrile is treated mixture. The invention disclosed 3 - ethoxy acrylonitrile and 3, 3 - diethyl dimethoxypropionitrile is treated mixture of the synthetic method has low material cost, relatively mild reaction conditions, the operation is simple, the yield and the like, which is suitable for the industrial production, application of the method.

- Process for producing an acetal
-
An acetal is produced at a high yield and a high selectivity by contacting an olefin and an alcohol with each other in the presence of (a) a nitrite, (b) a platinum group metal or the salts thereof and (c) a halide at a high reaction rate without requirement of any troublesome operations for the separation, recovery and regeneration of the catalyst.
