ABSTRACT:
Process for the production of 2-chlorobuta-1,3-diene (chloroprene) which comprises reacting 3,4-dichlorobut-1-ene and sodium butylate in n-butanol to produce a reaction mixture containing the 2-chlorobuta-1,3-diene and sodium chloride in the n-butanol with the sodium chloride being a suspended solid. The reaction mixture is distilled in a distillation column to separate the 2-chlorobuta-1,3-diene as top product and n-butanol having the sodium chloride suspended therein as sump product. The reaction can be performed in the distillation column.
