GLYCIDOL PREPARATION |
| 摘要 |
This invention relates to an improved one-pot synthetic process for the preparation of glycidol from the reaction of glycerol and dimethyl carbonate. More specifically, the invention relates to a one-pot synthetic process for the preparation of glycidol comprising the reaction of glycerol and dimethyl carbonate in the presence of an ionic liquid catalyst having the formula: [Cat+][X] wherein: [Cat] represents one or more cationic species, and [X] represents one or more anionic species; wherein the reaction is conducted at a temperature of from 100° C. to 160° C. and wherein the molar ratio of glycerol to dimethylcarbonate is from 1:4 to 1:10. |

1. A one-pot synthetic process for the preparation of glycidol comprising the reaction of glycerol and dimethyl carbonate in the presence of an ionic liquid catalyst having the formula:
[Cat+][X−] wherein: [Cat+] represents one or more cationic species, and
[X−] represents one or more anionic species;wherein the reaction is conducted at a temperature of from 100° C. to 160° C. and wherein the molar ratio of glycerol to dimethylcarbonate is from 1:4 to 1:10. |
