Abstract
Los productos que contienen 3-hidroxilactona cristalina se pueden preparar en alto rendimiento y pureza en un proceso que se desarrolla en un unico reactortratando el 3,5-dihidroxi ácido correspondiente con un ácido mineral fuerte en un solvente frío , aprotico, miscible con agua, para efectuar la formacion delactonas, seguido por el agregado de exceso de ácido para efectuar la cristalizacion del producto lactonizado a partir de la mezcla de reaccion.Products containing crystalline 3-hydroxylactone can be prepared in high yield and purity in a process that is developed in a single way by re-treating the corresponding 3,5-dihydroxy acid with a strong mineral acid in a cold, aprotic, water-miscible solvent. to effect the formation of the lactones, followed by the addition of excess acid to effect the crystallization of the lactonized product from the reaction mixture.
