Abstract
PURPOSE: To obtain high-purity butene-1 in high yield, by polymerizing a butane- butene fraction containing isobutylene and butene-1 under specific conditions in two reaction steps to a low polymer with a slight loss of the butene -1, and distilling the resultant reaction mixture.
CONSTITUTION: A butane-butene fraction containing 0.1W15wt% isobutylene and 10W50wt% butene-1 is continuously passed from a pipe 1 through the first reactor (R1) packed with particles of a strongly acidic cation exchange resin having an average particle diameter of 0.2W10mm at 30W100°C, a liquid space velocity of 0.1W50(1/hr) and a pressure of 1W50 atm, and the mixture at the outlet is then divided into two. One of them is circulated through the reactor (R1) and the other is passed from a pipe 4 through the second reactor (R2) packed with the same ion exchange resin particles as in the reactor (R1) under the same conditions as in the first reactor (R1) The bottoms are distilled in a distilling column (D1) to give an isobutylene low polymeric fraction from a pipe 6. The overhead fraction is then distilled in distilling columns (D2) and (D3) to afford the aimed high-purity butene-1.
