Abstract
UN PROCEDIMIENTO PARA LA OBTENCION DE LA VITAMINA K 1}, QUE CONSISTE EN QUE SE OXIDA UNA SAL DE METAL ALCALINO, EN PARTICULAR LA SAL DE SODIO O DE POTASIO, DE LA DIHIDROVITAMINA K{SUB,1} CON PEROXIDO DE HIDROGENO EN PRESENCIA DE UNA SAL DE HIERRO-(III), EN PARTICULAR EL SULFATO DE HIERRO-(III), Y A UN PH DE APROXIMADAMENTE 13,7 A APROXIMADAMENTE 14,3. PARA LA OBTENCION DE LA SAL DE METAL ALCALINO DE LA DIHIDROVITAMINA K{SUB,1} SE SAPONIFICA UN DIESTER DE LA DIHIDROVITAMINA K{SUB,1}, EN PARTICULAR EL BENZOATO DE ACETATO CON HIDROXIDO DE SODIO O DE POTASIO. POR CONVENIENCIA, SE PONE EN CONTACTO EL PRIMER PROCEDIMIENTO CON EL SEGUNDO, SIN QUE SE AISLE EL PRODUCTO DE SAPONIFICACION DIHIDROVITAMINA K{SUB,1}-SAL DE SODIO O POTASIO. CADA PROCEDIMIENTO SE REALIZA PREFERENTEMENTE EN UNA MEZCLA ACUOSA-ORGANICA DE DOS FASES DE DISOLVENTES, QUE SE COMPONE PREFERIBLEMENTE DE METANOL ACUOSO Y ETER DE PETROLEO.
