US Patent:

50736639, Dec 17, 1991

Filed:

Jan 31, 1990

Appl. No.:

7/472844

Inventors:

Gustavo Cerri - Boonton NJ
Robert C. Michaelson - Kinnelon NJ

Assignee:

Exxon Chemical Patents Inc. - Linden NJ

International Classification:

C07C 523

US Classification:

585668

Abstract:

A method for increasing the ratio of 2-methyl-2-butene (2MB2) to 2-methyl-1-butene (2MB1) in isoamylenes involves fractionating a feedstream containing tertiary amyl methyl ether (TAME) and isoamylenes including 2MB2 and 2MB1 in a ratio of about 2:1 to effect a separation between an overhead hydrocarbon fraction of isoamylenes including 2MB2 and 2MB1 in a ratio of about 1:1, a bottoms fraction including TAME, and a sidestream hydrocarbon fraction consisting essentially of isoamylenes including 2MB2 and 2MB1 in a ratio of about 6 to 12:1, recovering the sidestream hydrocarbon fraction, and recycling the overhead hydrocarbon fraction of isoamylenes to form a mixture which is subsequently reacted to form the feedstream. Prior to fractionation, the feedstream is formed by passing isoamylene, and optionally TAME, in a vapor phase over an ether cracking catalyst which isomerizes isoamylene and converts 2MB1 to 2MB2, i. e. , the feedstream for fractionating, which contains 2MB2 and 2MB1 in a ratio of 2 to 5:1.

Assignee:

Exxon Chemical Patents Inc. - Linden NJ

International Classification:

C07C 4106
C07C 4144

US Classification:

568697

Abstract:

In a process for separating C. sup. 4 to C. sup. 7 tertiary mono-olefins(s) present in a C. sup. 4 to C. sup. 7 hydrocarbon mixture containing diolefins which comprises selectively reacting said tertiary mono-olefin mixture with a primary alcohol in the presence of an acid catalyst to convert it to tertiary ether(s), separating the tertiary ether(s) from the unreacted hydrocarbon mixture and containing said tertiary ether(s) in the presence of a catalyst to decompose it to tertiary olefin(s) and a primary alcohol, the improvement which comprises hydrogenating the tertiary ether(s) after it has been separated from the unreacted hydrocarbon mixture and prior to decomposition to saturate the unsaturated ether(s) formed from the diolefins present in the hydrocarbon mixture.
