Abstract
SE DESCRIBE UN NUEVO AGENTE SEPARADOR ACUOSO QUE CONTIENE COMO SUSTANCIAS DE EFECTO SEPARADOR ACEITE Y/O CERAS EMULSIONADAS EN AGUA COMO MEDIO DE DISOLUCION Y SE CARACTERIZA PORQUE COMO OTRA SUSTANCIA DE EFECTO SEPARADOR CONTIENEN UNA O VARIAS AMINAS ALIFASTICAS PRIMARIAS, SECUNDARIAS Y/O TERCIARIAS CON AL MENOS UN RESIDUO DE ALQUIL C12 - C14 Y COMO EMULSIONADOR PARA LA O LAS AMINAS UNA O VARIAS SALES DE AMONI. EL INVENTO ALUDE A LA SORPRENDENTE VERIFICACION DE QUE LAS AMINAS HIDROFOBAS (LLAMADAS AMINAS GRASAS) PRESENTAN SUSTANCIAS DE EFECTOS SEPARADORES. ADEMAS SEGUN EL INVENTO SE MUESTRA SORPRENDENTEMENTE QUE LA DESMOLDEABILIDAD AL UTILIZAR LAS SALES DE AMONIO COMO EMULSIONADOR AL CONTRARIO DE LAS EXPERIENCIAS CON EMULSIONADORES TRADICIONALES NO EMPEORA SINO QUE MEJORA FRECUENTEMENTE. EL AGENTE SEPARADOR SEGUN EL INVENTO ES ADECUADO ESPECIALMENTE PARA UTILIZACION EN PROCEDIMIENTOS PARA LA FABRICACION DE OBJETOS DE ESPUMA DE POLIURETANO.
