Filed:

Jun 26, 2001

Appl. No.:

09/892177

Inventors:

Saleh Elomari - Fairfield CA, US
Richard Reynolds - Point Richmond CA, US
Steven Herron - Houston TX, US

International Classification:

C07C007/00

US Classification:

585/867000, 585/864000, 585/866000

Abstract:

A process for the separation of conjugated olefins from monoolefins in a fluid comprising such conjugated olefins and monoolefins using a Diels-Alder reaction to provide a fluid comprising a Diels-Alder adduct and monoolefins. The fluid comprising such Diels-Alder adduct and monoolefins can be subjected to a separating means to thereby recover a resulting monoolefin-containing fluid containing less than about 50 parts per million conjugated olefins. The process is particularly useful for purification of fluids containing normal alpha olefins.

International Classification:

C07C007/00

US Classification:

585/810000

Abstract:

A method for removing conjugated olefins from a composition comprising contacting the composition with a Diels-Alder dienophile to convert conjugated olefins to a Diels-Alder adduct and arresting the Diels-Alder adduct. A method comprising confining a Diels-Alder dienophile to a first side of a selectively permeable barrier wherein the barrier is more permeable to conjugated olefins and less permeable to Diels-Alder dienophile and Diels-Alder adduct, and contacting a composition comprising mono-olefins and conjugated olefins with the Diels-Alder dienophile to form Diels-Alder adduct, wherein the contacting reduces the concentration of conjugated olefins in the composition. A method for removing conjugated olefins from a composition comprising bubbling the composition through a liquid comprising Diels-Alder dienophile to form a liquid comprising Diels-Alder adduct. A method for removing conjugated olefins from a non-solid composition comprising contacting the composition with a solid comprising Diels-Alder dienophile to form a solid comprising Diels-Alder adduct.

US Classification:

2603436

Abstract:

A process for producing a lactone-substituted aniline wherein an alpha-halo-gamma-butyrolactone is reacted with an aniline in the presence of water at a temperature between 80. degree. and 160. degree. C. Thus, 3-(N-2,6-dimethylphenylamino)-gamma-butyrolactone is prepared by reacting an alpha-halo-gamma-butyrolactone with 2,6-dimethylaniline in the presence of water and an inert organic solvent at a temperature between 80. degree. and 160. degree. C. This process is advantageously combined with a subsequent acylation step to provide a continuous means for making materials such as 3-(N-chloroacetyl-N-2,6-dimethylphenylamino)-gamma-butyrolactone.

US Classification:

549 63

Abstract:

A process for making a compound of the formula ##STR1## which process comprises contacting, in the absence of an acid acceptor, an acyl halide with an aniline substituted gamma-butyrolactone in the presence of a non-basic solvent and at a temperature between 65. degree. and 150. degree. C. Thus, 3-(N-chloroacetyl-N-2,6-dimethylphenylamino)-gamma-butyrolactone is prepared by a process comprising contacting, in the absence of an added acid acceptor, chloroacetylchloride with 3-(N-2,6-dimethylphenylamino)-gamma-butyrolactone in the presence of a non-basic organic solvent and at a temperature between 65. degree. and 150. degree. C. Preferably, the 3-(N-2,6-dimethylphenylamino)-gamma-butyrolactone is formed by reacting alpha-bromo-gamma-butyrolactone with dimethylaniline in the presence of water and in a non-basic organic solvent, and the 3-(N-2,6-dimethylphenylamino)-gamma-butyrolactone in the organic solvent is phase separated and fed straight through to the acetylation step.
