Assignee:
Eastman Chemical Company - Kingsport TN
International Classification:
C07C 51/16
US Classification:
562412, 562416, 562480
Abstract:
Methods and apparatus for producing a carboxylic acid employing a solvent from esterification of lignocellulosic materials.

Filed:
Mar 27, 2012
Appl. No.:
13/431358
Inventors:
Scott Donald Barnicki - Kingsport TN, US
Robert Thomas Hembre - Johnson City TN, US
Stephen Neal Falling - Kingsport TN, US

Assignee:
EASTMAN CHEMICAL COMPANY - Kingsport TN
International Classification:
C07C 51/12
US Classification:
562518
Abstract:
Disclosed is a process for the production and purification of glycolic acid or glycolic acid derivatives by the carbonylation of formaldehyde in the presence of a solid acid catalyst and a carboxylic acid. This invention discloses hydrocarboxylations and corresponding glycolic acid separations wherein the glycolic acid stream is readily removed from the carboxylic acid and the carboxylic acid is recycled.
