Abstract

1,265,029. Isophorone. ESSO RESEARCH & ENG. CO. 2 June, 1969, No. 27736/69. Heading C2C. Isophorone is purified by subjecting a crude isophorone stream comprising isophorone, betaisophorone, phorone, beta-phorone, lighter boiling impurities and heavier boiling impurities to distillation in a first distillation column to separate heavier boiling impurities as a bottoms product and recovering an overhead product comprising isophorone, beta-isophorone, phorone, beta-phorone, and lighter boiling impurities, subjecting the overhead product to distillation in a second distillation column, and recovering a substantially purified isophorone from a point in the second column below that at which the feed is introduced. If desired the feed to the second column may be heated prior to the entry thereto to isomerize beta-isophorone to isophorone.
