Abstract: The invention relates to a method for separating a C4 hydrocarbon mixture containing essentially 1,3 butadiene, butenes, butanes and other C4 hydrocarbons into at least 4 fractions as follows: a) fraction (a) consisting essentially of 1,3 butadiene; b) fraction (b) consisting essentially of butenes; c) fraction (c) consisting essentially of butanes; and d) one or more fractions (d) consisting essentially of 1,3 butadiene and the other C4 hydrocarbons. According to said method, the C 4 hydrocarbon mixture is separated by extractive distillation using N-methyl-2-pyrrolidinone or an aqueous solution of N-methyl-2- pyrrolidinone (NMP).

Abstract: A C4-hydrocarbon mixture essentially containing 1,3-butadiene, butenes, butanes and other C4-hydrocarbons is separated into at least 4 fractions,a) the fraction (a) essentially comprising 1,3-butadiene,b) the fraction (b) essentially comprising butenes,c) the fraction (c) essentially comprising butanes andd) one or more fractions (d) essentially comprising 1,3-butadiene and the other C4-hydrocarbons,by extractive distillation by means of N-methyl-2-pyrrolidinone or an aqueous solution of N-methyl-2-pyrrolidinone (NMP).
