Abstract
A process for producing chloroprene from 3,4-dichlorobutene-1 and sodium hydroxide solution wherein a dehydrated mixture of n-butanol and aqueous sodium hydroxide solution is reacted with 3,4-dichlorobutene-1 to form chloroprene and solid sodium chloride.
Claims5
A process for producing chloroprene which comprises dehydrating a mixture of an aqueous alkali metal hydroxide solution and n-butanol by azeotropic distillation, then reacting resulting dehydrated mixture with 3,4-dichlorobutene-1, removing insoluble alkali metal chloride from resulting reaction mixture and distilling resulting liquid reaction product to separate chloroprene and n-butanol.
