Abstract

PROCEDIMIENTO PARA LA OBTENCION DEL ACIDO B-HIDROXIBULTIRICO O DE SUS OLIGOCONDENSADOS A PARTIR DE SUS PRODUCTOS DE POLICONDENSACION. CONSISTE EN SOMETER LOS PRODUCTOS DE POLICONDENSACION A HIDROLISIS A UNA TEMPERATURA ENTRE 25 Y 150 C, EN UNA MEZCLA CON UN DISOLVENTE ORGANICO HALOGENADO Y AGUA, EN PRESENCIA DE UN CATALIZADOR ACIDO CUYO PKA ES INFERIOR A 4, TAL COMO ACIDO SULFURICO O DERIVDOR SULFONICOS. LA MEZCLA DE REACCION SE CONCENTRA A MEDIDA QUE PROGRESA LA HIDROLISIS, POR DESTILACION DEL DISCOLVENTE HASTA SU ELMINACION, PROSIGUIENDO LA HIDROLISIS EN MEDIO ACUOSO. EL ACIDO B-HIDROXIBUTIRICO TIENE APLICACIONES COMO INTERMEDIARIO EN LA SINTESIS ORGANICA Y LOS PRODUCTOS DE OLIGOCONDENSACION COMO RESERVA ENERGETICA EN NUTRICION ANIMAL.
