Prospects for development of a technology for production of butene-1

Industrial technologies for production of butene-1 are described, including the most promising process for recovery of butene-1 of polymerization purity from C4 fractions formed in pyrolysis and catalytic cracking of hydrocarbons. It is shown that this technology can be improved and suggested to use as a raw material the recycle butene fraction formed from these C4 fractions upon isolation of 1,3-butadiene and isobutene. A technological scheme for recovery of butene-1 of polymerization purity is suggested.
