Abstract

_(PROCEDIMIENTO PARA LA OBTENCION DE UN AGLOMERANTE DE MATERIAL DE MOLDEO ENDURECIBLE EN FRIO . CONSISTE EN CONDENSAR ENTRE SI EN UNA PROPORCION DE 1 A 10 MOLES DE UN COMPUESTO FENOLICO CON AL MENOS DOS ATOMOS DE HIDROGENO ACIDOS CON 2 A 20 MOLES DE FORMOLDEHIDO Y DE 2 A 20 MOLES DE UNA AMINA ALIFATICA PRIMARIA O SECUNDARIA. A CONTINUACION EL AGUA DE REACCION FORMADA SE DESTILA Y ELIMINA. COMO AMINA SE EMPLEA UNA QUE CONTIENE GRUPOS OH PRIMARIOS. COMO COMPUESTO FENOLICO, SE EMPLEA UN PRECONDENSADO DE UN FENOL CON UN ALDEHIDO O CETONA QUE CONTIENE GRUPOS METILOL TERMINALES.
