Assignee:

Petro-Tex Chemical Corporation - Houston TX

International Classification:

C07C 5327

US Classification:

585658

Abstract:

Filed:

Aug 12, 1983

Appl. No.:

6/522603

Inventors:

Donald A. Keyworth - Houston TX
Cecil G. McFarland - League City TX

Assignee:

Petro-Tex Chemical Corporation - Houston TX

International Classification:

C07C 100
C07C 700
C07C 712
C07C 408

US Classification:

585312

Abstract:

MTBE can be dissociated with high selectivity to isobutene and methanol over acid action exchange resin catalysts using very high LHSV, e. g. of 7 to 35 at pressure drops of 0. 5 to 50 psig through the fixed bed at reaction pressure of 0. 5 to 4 atmospheres and bed temperatures in a fixed bed tubular-reactor in the range of 90. degree. C. to 160. degree. C. Good conversions are obtained and undissociated MTBE and by-products of the dissociation may be recycled to a liquid phase MTBE synthesis.

Filed:

Jun 8, 1989

Appl. No.:

7/363591

Inventors:

Cecil G. McFarland - Houston TX

Assignee:

Texas Petrochemicals Corporation - Houston TX

International Classification:

C07C 509
C07C 5327

US Classification:

585658

Abstract:

Cofeeding butylenes with amylenes in a catalytic oxidative dehydrogenation reaction substantially improves the conversion of the amylenes. The approved amylene conversion is obtained by the oxidative dehydrogenation of mixtures of amylenes and from 10 to 95 mole % butylenes.

Petro-Tex Chemical Corporation - Houston TX

International Classification:

C07C 204

US Classification:

585520

Abstract:

Conversions of over 80 mole % of n-butenes to oligomers can be obtained with less than 15 mole % C. sub. 12 or higher oligomers by passing a predominantly C. sub. 4 stream containing at least 40 mole % n-butenes through an acidic cation exchange resin at LHSV 2 to 5 at temperatures in the range of 80. degree. C. to 130. degree. C. , in liquid phase by cofeeding from 1 to 5 weight %, based on the C. sub. 4 stream, of methyl tertiary butyl ether, secondary butyl methyl ether, toluene or mixtures thereof.
