摘要：
Highly pure butene-1 and butene-2 are sepd. from isobutane, n-butane, butene-1, butene-2, diolefinic hydrocarbons and acetylenic hydrocarbons. The process comprises (i) 1st extn. stage: separate rafinate(contg. isobutane, n-butane) and extracts(contg. butene-1, - 2, diolefinics, acetylenics) in the 1st extn.-distn. column by use of polar solvent, (ii) 1st distn. stage: obtain crude oil(butene-1, diolefinics, acetylenics) from upper column and refined butene-2 from lower column, (iii) 2nd extn. distn. stage: for highly pure butene-1 and (iv) 2nd distn. stage: for butene-2.
