Abstract

PROCEDIMIENTO DE OBTENCION DE RESINA DE FENOL FORMALDEHIDO. CONSISTE EN CONDENSAR UN FENOL, TAL COMO FENOL PROPIAMENTE DICHO, ALQUIFENOL, METILFENOL ODIMETILFENOL, CON UN FORMALDEHIDO PREFERIBLEMENTE EN FORMA DE PARAFORMALDEHIDO O FORMALINA, EN PRESENCIA DE UN AZUCAR REDUCTOR, TAL COMO LA LACTOSA Y/O GALACTOSA, PUDIENDO EMPLEARSE TAMBIEN SUERO DE LECHE SECA POR ATOMIZACION EN LUGAR DE LACTOSA PROPIAMENTE DICHA. SE EMPLEA UN CATALIZADOR ACIDO OXADICO, SALICILICO CLORHIDRICO O MEZCLA DE ESTOS, EN UNA CANTIDAD COMPRENDIDA ENTRE 0,05 Y 5 POR 100 SOBRE EL PESO TOTAL DE LOS INGREDIENTES DE REACCION. LA CONDENSACION DE FENOL SE EFECTUA A TEMPERATURAS PROXIMAS A 100GC O MAS DURANTE 1 HORA COMO MINIMO; LA RELACION DE FENOL A FORMALDEHIDO ES SUPERIOR A 1:1 E INFERIOR A 6:1.
