Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
C07C 6996
US Classification:
558277

Integrated Process For Preparing Dialkyl Carbonates And Diols

US Patent:
6407279, Jun 18, 2002
Filed:
Nov 19, 1999
Appl. No.:
09/444231
Inventors:
J. Scott Buchanan - Trenton NJ
Zhaozhong Jiang - Thorofare NJ
Jocelyn A. Kowalski - Sewell NJ
Jose G. Santiesteban - West Chester PA
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
C07C 6996
US Classification:
558277, 558260
Abstract:
An integrated process for the production of a dialkyl carbonate and a diol from an alkylene oxide, carbon dioxide and an aliphatic monohydric alcohol is described in which an alkylene oxide is first reacted with carbon dioxide in the presence of a carbonation catalyst to provide a corresponding cyclic carbonate and impurities and the cyclic carbonate, which contains the impurities, is then reacted with an aliphatic monohydric alcohol in the presence of a transesterification catalyst to provide a corresponding dialkyl carbonate and diol.

Co-Production Of Dialkyl Carbonates And Diols With Treatment Of Hydroxy Alkyl Carbonate

View page
US Patent:
6573396, Jun 3, 2003
Filed:
Oct 12, 2001
Appl. No.:
09/976608
Inventors:
J. Scott Buchanan - Lambertville NJ
Jose G. Santiesteban - Bethlehem PA
Zhaozhong Jiang - Edison NJ
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
C07C 6996
US Classification:
558277, 568840
Abstract:
A process for the production of a dialkyl carbonate and a diol from a cyclic carbonate and an aliphatic monohydric alcohol wherein the cyclic carbonate and aliphatic monohydric alcohol are reacted in the presence of a transesterification catalyst to form a crude product stream which contains a dialkyl carbonate, a diol, a hydroxy alkyl carbonate, which is formed as an intermediate of the two step transesterification reaction, unreacted aliphatic monohydric alcohol and unreacted cyclic carbonate. The dialkyl carbonate and unreacted aliphatic monohydric alcohol are separated from the crude product stream and then the hydroxy alkyl carbonate is diminished, reduced or eliminated from the crude product stream, prior to the separation and purification steps needed to recover the diol, resulting in improved yields and product purity.

Process For The Production Of Unsymmetric And/Or Symmetric Dialkyl Carbonates And Diols

View page
US Patent:
6620959, Sep 16, 2003
Filed:
Apr 16, 2002
Appl. No.:
10/123717
Inventors:
J. Scott Buchanan - Lambertville NJ
Zhaozhong Jiang - Edison NJ
Jose Guadalupe Santiesteban - Bethlehem PA
William A. Weber - Burlington NJ
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
C07C 6996
US Classification:
558277
Abstract:
A process for the production of a dialkyl carbonate and a diol, such as dimethyl carbonate and ethylene glycol, by reacting a feed containing a cyclic carbonate, a hydroxy alkyl carbonate and an aliphatic monohydric alcohol in the presence of a transesterification catalyst is described. In another aspect, a process is described which is particularly useful for producing unsymmetric dialkyl carbonates, such as ethyl methyl carbonate.

Low Corrosive Integrated Process For Preparing Dialkyl Carbonates

US Patent:
6774256, Aug 10, 2004
Filed:
Mar 25, 2002
Appl. No.:
10/105550
Inventors:
Richard H. Schlosberg - Bridgewater NJ
J. Scott Buchanan - Lambertville NJ
Jose Guadalupe Santiesteban - Bethlehem PA
Zhaozhong Jiang - Edison NJ
William A. Weber - Burlington NJ
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
C07C 6996
US Classification:
558277
Abstract:
An integrated process for the production of a dialkyl carbonate and a diol from an alkylene oxide, carbon dioxide and an aliphatic monohydric alcohol is described in which an alkylene oxide is first reacted with carbon dioxide in the presence of a halogen-free carbonation catalyst to provide a corresponding cyclic carbonate and the cyclic carbonate is then reacted with an aliphatic monohydric alcohol in the presence of the carbonation catalyst and/or a transesterification catalyst and recycling the carbonation catalyst to provide a corresponding dialkyl carbonate and diol, wherein the dialkyl carbonate product exhibits a halogen concentration of about 5 ppm or less.

International Classification:
C07C 69/96
US Classification:
558277
Abstract:
An integrated process for the production of a dialkyl carbonate and a diol from an alkylene oxide, carbon dioxide and an aliphatic monohydric alcohol is described in which an alkylene oxide is first reacted with carbon dioxide in the presence of a homogeneous carbonation catalyst to provide a corresponding cyclic carbonate and the cyclic carbonate is then reacted with an aliphatic monohydric alcohol in the presence of the homogeneous carbonation catalyst and/or a heterogeneous transesterification catalyst and recycling the homogeneous carbonation catalyst to provide a corresponding dialkyl carbonate and diol.
