Abstract
PROCEDIMIENTO PARA INHIBIR LA DESCOMPOSICION DE FLUIDOS COLAGENOS CLOROFLUORADOS. CONSISTE EN CALENTAR ENTRE 120 Y 180JC A UNA MEZCLA DE N-METIL-PIRROLIDONA DE HIDROCARBUROS CLOROFLUORADOS, EN CONTACTO CON UN METAL Y EN PRESENCIA DE UNA SAL METALICA DE FORMULA (I). SIENDO: AR, RESTO AROMATICO CON UNO O VARIOS NUCLEOS AROMATICOS CONDENSADOS; M, ATOMO DE METAL; R, RADICAL ALQUILO DE CADENA LINEAL O RAMIFICADA DE C 1 A 15; M, 1 A 3 (ENTEROS); Y N, VALENCIA DEL METAL. LA SAL METALICA SE ELIGE ENTRE EL DINONILNAFTALENOSULFONATO DE BARIO, DE ZINC Y EL DODECILBENCENOSULFONATO DE CALCIO Y EL METAL SE ELIGE ENTRE FE, CU Y AL, Y EL HIDROCARBURO CLOROFLUORADO SE ELIGE ENTRE CLORO-1-TRIFLUOR-2,2,2-ETANO O EL CLORO-1-TETRAFLUOR-1,2,2,2-ETANO. SE UTILIZA EN BOMBAS DE CALOR O DE ABSORCION.
