Abstract

PROCEDIMIENTO PARA PREPARAR ACIDO B-HIDROXI-B-METILGLUTAR ICO.CONSISTE EN OXIDAR 3-METIL-1,3,5-PENTANOTRIOL CON UNA SAL DE PERMANGANATO EN UN MEDIO ACUOSO, A UNA TEMPERATURA COMPRENDIDA ENTRE 10 Y 110 GRADOS. DESPUES DE VERIFICADA LA REACCION SE RECUPERA EL ACIDO B-HIDROXI-B-METILGLUTARI CO. LA SAL DE PERMANGANATO SE SELECCIONA DEL GRUPO FORMADO POR PERMANGANATO DE SODIO Y PERMANGANATO DE POTASIO. EN DICHA REACCION SE DEBEN EVITAR EN LO POSIBLE LAS CONDICIONES DE REACCION FUERTEMENTE ACIDAS DEBIDO A LA SUSCEPTIBILIDAD DE DESHIDRATACION DEL ACIDO B-HIDROXI-B-METILGLUTARICO.
