Title:
【発明の名称】ポリオールポリエステル製造のための連続エステル交換法
Document Type and Number:
Japanese Patent JPH11506735
Kind Code:
A
Abstract:
Polyol polyesters can be made by a transesterification reaction of a polyol with a lower alkyl fatty acid ester. A by product of that reaction are the alcohols from the lower alkyl esters. These are usually removed from the transesterification reaction by inert gas stripping. The process herein links the transesterification reaction with a lower alkyl ester formation reaction. The transesterification reaction acts as a the source of the lower alkyl alcohols for the formation of the lower alkyl esters used in the polyol fatty acid polyester synthesis. A preferred method for both reactions uses a reactive absorption column.
