Title:
METAL OXIDE CATALYSTS FOR ETHERIFICATION, METHOD FOR ITS PREPARATION THEREOF, AND METHOD FOR THE PRODUCTION OF LINEAR POLYGLYCEROL USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/044531
Kind Code:
A3
Abstract:
The present invention relates to a metal oxide catalyst represented by the following Formula 1, which is useful for the production of linear polyglycerol via etherification of glycerol, and a method for its preparation thereof: [Formula 1] (CaO)a˙Ca12Al14O33)100-a wherein a refers to a weight ratio of CaO based on 100 parts by weight of the total catalyst. When the alkaline binary metal oxide catalyst according to the present invention is used in the glycerol etherification, it can produce a large amount of linear polyglycerol glycerol. Therefore, the metal oxide catalyst prepared according to the present invention can be effectively used in the production of polyglycerol suitable as cosmetic or food additives.
