Filed:

Aug 27, 2009

Appl. No.:

12/583871

International Classification:

C07C 51/42
C07C 53/10

US Classification:

562608, 562607

Abstract:

A method for reducing aldehydes in an acetic acid production process is disclosed. The acetic acid is produced by reacting methanol and carbon monoxide in the presence of a carbonylation catalyst. The method comprises reacting an aldehyde-containing stream with an alcohol to form an acetal-containing stream. An acetal-enriched stream is separated from the acetal-containing stream and then hydrolyzed to form a hydrolysis mixture comprising the alcohol and the aldehydes. The alcohol is isolated from the hydrolysis mixture and used to react with the aldehyde-containing stream to form the acetal-containing stream. The invention reduces aldehydes in the acetic acid produced.

Filed:

Dec 19, 2012

Appl. No.:

13/720539

Inventors:

Michael E. Fitzpatrick - League City TX, US
Miraj S. Patel - Sugar Land TX, US

International Classification:

C07C 51/44
C07C 51/12

US Classification:

562519, 203 67, 203 87

Abstract:

The phase separation in the decanter of a process for producing acetic acid by carbonylating methanol in the presence of a catalyst under low water-high acid conditions is facilitated and expedited by forming a liquid mixture (D) which has a water content of at most 10% by weight, based on the weight of the liquid mixture, an acetic acid content of at least 10% by weight, based on the weight of the liquid mixture, and a weight ratio of methyl iodide to methyl acetate of at least 1.5:1, and partitioning the liquid mixture at a temperature of from 0 to 35 C.

International Classification:

C07C 51/44

US Classification:

568909

Abstract:

The phase separation in the decanter of a process for producing acetic acid by carbonylating methanol in the presence of a catalyst under low water-high acid conditions is improved by forming a liquid mixture (D) which has a water content of at most 20% by weight, based on the weight of the liquid mixture, and a weight ratio of acetic acid to water of at least 1:1, and partitioning the liquid mixture by providing for an alkane(s) content of D of from 0.1 to 15% by weight, based on the weight of D, to obtain a light, aqueous phase and a heavy, organic phase.

International Classification:

C07C 51/12
B01J 31/02
B01J 31/10
C07C 51/44

Abstract:

The present technology relates to the production and recovery of acetic acid. The recovery processes may include providing a first process stream including acetic acid and greater than 250 ppm of propionic acid; separating at least a portion of the propionic acid from the acetic acid within the first process stream to provide an acetic acid stream including acetic acid and less than 250 ppm of propionic acid and a bottoms stream including propionic acid and acetic acid; reacting the bottoms stream to form a product stream including components of respectively lower boiling points than corresponding components in the bottoms stream; and separating components of the product stream to form an overhead stream including one or more acetates and a bottoms stream including one or more propionates.
