Abstract
UN PROCESO PARA LA PRODUCCION DE SEMICARBAZIDAS QUE CONSISTE EN HACER REACCIONAR UN COMPUESTO DE LA FORMULA (I) CON AMONIACO ANTE LA PRESENCIA O AUSENCIA DE UN CATALIZADOR QUE CONTIENE UN COMPLEJO DE CLORURO, HIDROXIDO, SULFATO, CARBONATO, ACETATO, SALICILATO Y AMINA O UN COMPLEJO DE ETILENODIAMINA DE CINC O CADMIO O UNA MEZCLA DE LOS MISMOS. ESTE PROCESO ES VENTAJOSO PORQUE NO EXISTE EL PROBLEMA DE TENER QUE UTILIZAR UNA GRAN CANTIDAD DE HIDROXIDO SODICO Y DE GENERAR UN SUBPRODUCTO DE CARBONATO SODICO.
