Abstract

SE PRESENTAN METODOS PARA PRODUCIR METILOLHIDANTOINAS ANHIDROSAS SOLIDAS. INICIALMENTE, SE DESHIDRATA UN MEDIO DE AGITACION ACUOSO Y SE CALIENTA PARA PRODUCIR UNA FUSION DE AGITACION SUSTANCIALMENTE ANHIDROSA. EL MEDIO DE AGITACION ANHIDROSO COMPRENDE (A), UN SOLUTO ELEGIDO ENTRE EL GRUPO QUE CONSISTE EN (I) UNA DIMETILOLDIMETILHIDANTOINA, (II) UN REACTANTE DE HIDANTOINA, (III) UN REACTANTE DE FUENTE DE FORMALDEHIDO, O (V) UNA COMBINACION DE CUALQUIER DE LOS ANTERIORES: Y (B) OPCIONALMENTE UN CATALIZADOR.SE PRESENTA UN SISTEMA DE FUNDICION AÑADIENDO, A LA FUSION DE AGITACION, UNA MEZCLA REACTANTE QUE COMPRENDE (A)(I) EL MISMO REACTANTE DE HIDANTOINA U OTRO DISTINTO, (II) UN REACTANTE DE FUENTE DE FORMALDEHIDO SUSTANCIALMENTE ANHIDROSO QUE PUEDE SER IGUAL O DISTINTO DEL REACTANTE DE FUENTE DE FORMALDEHIDO, 0 (II) UNA COMBINACION DE ESTOS; Y (B) OPCIONALMENTE, EL MISMO O UN CATALIZADOR DISTINTO; EN EL QUE EL SISTEMA DE FUNDICION INCLUYE (I) AL MENOS UN REACTANTE DE HIDANTOINA Y (II) AL MENOSUN REACTANTE DE FUENTE DE HIDANTOINA DESHIDRATA O SU REACTANTE DE FUENTE DE FORMALDEHIDO SUSTANCIALMENTE ANHIDROSA. EL AL MENOS REACTANTE DE HIDANTOINA Y EL AL MENOS REACTANTE DE FUENTE DE FORMALDEHIDO DESHIDRATADO O REACTANTE DE FUENTE DE FORMALDEHIDO SUSTANCIALMENTE ANHIDROSO EN EL SISTEMA DE FUNDICION SON REACCIONADOS, MIENTRAS SE ELIMINA EL AGUA DE REACCION, PARA PRODUCIR METILOLHIDANTOINA FUNDIDA ANHIDROSA. FINALMENTE, LA METILOLHIDANTOINA FUNDIDA SE SOLIDIFICA. ALTERNATIVAMENTE, SE PRODUCE METILOLHIDANTOINA ANHIDROSA SOLIDA REACCIONAN, EN UN MEDIO DE AGITACION ACUOSO COMO ANTERIORMENTE, UNA MEZCLA DE REACTANTE (1) EL MISMO O DISTINTO REACTANTE DE HIDANTOINA, (II) UN REACTANTE DE FUENTE DE FORMALDEHIDO SUSTANCIALMENTE ANHIDORSA QUE PUEDE SER LA MISMA O UNA DISTINTA DEL REACTANTE DE FUENTE DE FORMALDEHIDO, O (III) UNA COMBINACION DE ESTOS Y (IV) OPCIONALMENTE, EL MISMO CATALIZADOR U OTRO DISTINTO; DONDE ESTA PRESENTE (I) AL MENOS UN REACTANTE DE HIDANTOINA Y (II) AL MENOS UN REACTANTE DE FUENTE DE FORMALDEHIDO O UN REACTANTE DE FORMALDEHIDO SUSTANCIALMENTE ANHIDROSO; MIENTRAS TANTO SE CALIENTA A AL MENOS LA TEMPERATURA DE FUSION DE LA METILOLHIDANTOINA Y SE ELIMINA SUSTANCIALMENTE EL AGUA; PARA PRODUCIR UNA METILOLHIDANTOINA FUNDIDA; Y A CONTINUACION SE SOLIDIFICA LA METILOLHIDANTOINA FUNDIDA: ESTOS METODOS PUEDEN SER PUESTOS EN PRACTICA COMO PROCESO INTERMITENTES O COMO PROCESOS SEMICONTINUOS.
