Title:
PROCESSES FOR PURIFICATION OF SUCCINIC ACID VIA DISTILLATION OR SUBLIMATION
Document Type and Number:
WIPO Patent Application WO/2013/088239
Kind Code:
A3
Abstract:
Processes for removing color bodies from crude succinic acid comprising distillation of crude succinic acid and collecting the distillate in a water-containing receiver. The color bodies substantially remain in the distillation bottoms and the purified succinic acid in the water-containing receiver is substantially free of color bodies. Alternatively, the color bodies can be removed using sublimation.
