| titleOfInvention | Method for manufacturing (2,2-dimethyl-1,3-dioxolan-4-yl)methanol |
| abstract | The present invention relates to a method for manufacturing solketal ((2,2-Dimethyl-1,3-dioxolan-4-yl)methanol) that comprises at least the following steps: (1) milling the following reagents, called starting reagents, comprising at least: glycerol, a catalyst selected from a hard Lewis acid comprising at least one transition metal, and acetone, the molar ratio (glycerol):(acetone) being less than or equal to 0.8; preferably less than or equal to 0.7, at an ambient temperature greater than or equal to 50°C, preferably greater than or equal to 56°C, in a three-dimensional microbead mill in a liquid phase for a residence time less than or equal to 15 minutes, preferably less than or equal to 10 minutes, and in particular less than or equal to 5 minutes; (2) recovering, as output from the mill, a final composition comprising solketal and, where appropriate, one or more sub-products corresponding to the starting reagents that have not reacted and/or to 1,3-O-isopropylidene-glycerol, and (3) optionally, separating the solketal from said one or more sub-products. |
