Abstract
The present invention relates to a process for producing glycidol from glycerol carbonate as a raw material with a high yield. The process for producing glycidol according to the present invention includes the steps of (1) reducing a content of a salt having a weak acidity in glycerol carbonate to 1500 ppm by mass or less; and (2) obtaining the glycidol from the glycerol carbonate.
Claims6
A process for producing glycidol, comprising the steps of:
- (1) reducing a content of a salt having a weak acidity in glycerol carbonate to 1500 ppm by mass or less;
- and
- (2) obtaining the glycidol from the glycerol carbonate.
A process for producing glycidol, comprising the steps of:
- (1) reducing a content of a salt having a weak acidity in glycerol carbonate to 1500 ppm by mass or less;
- and
- (2) obtaining the glycidol from the glycerol carbonate;
- wherein the glycerol carbonate is subjected to adsorption treatment to reduce the content of the salt having a weak acidity therein.
