| titleOfInvention | A process for the production of cyclic diesters of alpha-hydroxy acids |
| abstract | Process for the synthesis of a cyclic diester of an alpha-hydroxy acid, comprising the following steps: - a Mg, Ca, Zn, Al or Fe salt of the corresponding alpha-hydroxy acid is mixed with said alpha-hydroxy acid and water; - the mixture is treated by evaporation-crystallization, to precipitate a hydrate from the salt of Mg, Ca, Zn, Al or Fe of the linear dimer of the corresponding alpha-hydroxy acid; - the hydrated salt is dehydrated to give the corresponding anhydrous salt; and - the anhydrous salt is pyrolyzed, releasing the cyclic diester of the corresponding alpha-hydroxy acid and leaving the hydroxide of Mg, Ca, Zn, Al or Fe in the form of a solid residue. |
