Title:
METHOD FOR PRODUCING FATTY ACID ESTER AND METHOD FOR PRODUCING GLYCEROL
Document Type and Number:
Japanese Patent JP2006342328
Kind Code:
A
Abstract:

To provide a simple method for production with which a high-purity product (a fatty acid ester or glycerol) is obtained at a low cost/high reaction efficiency without requiring a step of separating a catalyst.

The method for producing the fatty acid ester from oils and fats and a monohydric alcohol comprises using a chemical catalyst. In the method, the excessive monohydric alcohol in a state of superheated vapor is continuously fed to a reaction system and subjected to a transesterification with the oils and fats. The resultant reaction product containing the fatty acid ester in a state of a vapor phase or a mixed phase accompanying a droplet-like phase thereof is continuously taken out together with the superheated vapor of the monohydric alcohol. Thereby, the fatty acid ester is separated and recovered.
