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.

Allyl acetate purification

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.

Process for producing allyl alcohol

A process for producing allyl acetate is disclosed. The process comprises reacting propylene, acetic acid, and oxygen in the presence of a supported palladium catalyst in an adiabatic reactor.

Process for producing allyl acetate

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.

Purification of N-(2-hydroxyethyl)-2-pyrrolidone

A propylene oxide/styrene monomer aqueous purge stream is contacted with a catalyst at conditions effective to decompose peroxides contained therein, and oxygen formed by the decomposition swept from the decomposition with a nitrogen vapor stream from ethylbenzene oxidation.

Peroxide impurities removal

Ethylbenzene hydroperoxide suitable for epoxidizing an olefin using a heterogeneous titanium catalyst is provided by the sequence of:

Process stream purification

A tertiary alkanol such as tertiary butyl alcohol is converted in one step to an oligomer of the olefin corresponding to the alkanol by reacting a homogeneous solution of the alkanol and an acid catalyst at conditions effective to form the oligomer.

Production of iso olefin oligomers

In the Oxirane process for epoxide production, at least part of the alcohol formed during isobutane or isopentane peroxidation is replaced by an inert solvent such as decane.

Olefin epoxidation process

The present invention relates to a process for the oxidation of isobutane in the liquid phase to produce TBA and TBHP wherein at least a portion of the oxidation product mixture is obtained as distillate from fractional distillation of vapors from the oxidation zone.

Oxidation of isobutane to tertiary butyl hydroperoxide

The present invention relates to a process for the oxidation of isobutane in the liquid phase to produce TBA and TBHP wherein at least a portion of the oxidation product mixture is obtained from the condensate of vapors from the oxidation zone.

A process for the hydrogenation of ACP to MBA over a supported palladium catalyst wherein a solvent comprised of ethylbenzene and/or MBA is employed and a small amount of water effective to suppress catalyst deactivation is incorporated in the feed. A further improvement comprises maintaining hydrogen pressure on the catalyst during and between hydrogenation runs.
