Abstract: A process for purifying allyl acetate is disclosed. An acetoxylation mixture is distilled at elevated pressure to remove propylene and generate a first bottoms mixture comprising allyl acetate, acetic acid, acrolein, allyl diacetate, and 3-acetoxypropionaldehyde. The first bottoms mixture is flash vaporized, and the resulting vapor is contacted with a solid acidic catalyst under conditions effective to decompose allyl diacetate and 3-acetoxypropionaldehyde. The flashed product, which comprises allyl acetate, acetic acid, and acrolein, is then distilled to remove acrolein and generate a second bottoms mixture comprising allyl acetate and acetic acid. The second bottoms mixture can be used to manufacture allyl alcohol.

Abstract: A process for producing allyl alcohol is disclosed. The process comprises reacting propylene, acetic acid, and oxygen to produce a reaction mixture. The reaction mixture is distilled to produce a vapor stream comprising propylene and a liquid stream comprising allyl acetate, acetic acid, acrolein, and allyl diacetate. The liquid stream is distilled to produce a lights stream comprising acrolein; a side draw comprising allyl acetate, acetic acid, and water; and a bottoms stream comprising acetic acid and allyl diacetate. The bottoms stream is distilled to remove a heavies stream comprising allyl diacetate. The side draw is hydrolyzed to produce allyl alcohol.

Abstract: A process comprising reacting a feed comprising isobutene and a modifier in the presence of an acidic solid catalyst to produce diisobutene is disclosed. The amount of the modifier in the feed is reduced as the catalyst ages. Lower reaction temperature is maintained throughout the catalyst life, which is less likely to corrode the reactor. When an alcohol is used as a modifier, a lower reaction temperature causes lower degree of dehydration of the modifier, thus lower water concentration is maintained, which in turn reduces the likelihood of reactor corrosion.

Abstract: N-(2-hydroxyethyl)-2-pyrrolidone (HEP) is purified by a distillation sequence in which the purified HEP is recovered as a side stream without being separated as an overhead at any point in the procedure.

Abstract: This invention is a process for producing diisobutylene from isobutylene. The process comprises contacting isobutylene with a solid adsorbent to remove sulfur and/or nitrogen impurities from the isobutylene, followed by oligomerizing the isobutylene to diisobutylene using a sulfonic acid-type ion exchange resin. The solid adsorbent removes sulfur and/or nitrogen impurities from the isobutylene and surprisingly increases both catalyst activity and catalyst life of the sulfonic acid-type ion exchange resin.
