Abstract

LOS 3 ESTERES DE ACIDO DE OXOCARBONO SE ELABORAN MEDIANTE LA ACILACION DE MAGNESIOMENOLATE DE ESTERES DE ACIDO ACETACETICO CON CLORIDOS DE ACIDO DE CARBONO Y SU DIVISION DE GRUPOS DE ACETILO DE LOS ESTERES DE ACIDO ACETACETICO DE ACILO, FORMADOS POR PRODUCTOS INTERMEDIOS. DEBIDO AL AÑADIDO DE UNA MINA TERCIARIA EN LA ACILACION, SE CONSIGUE UNA MEJOR LIMPIEZA Y RENDIMIENTO DE LOS PRODUCTOS.
