Abstract
LOS DIMEROS DE CETENA DE CADENA LARGA SE PREPARAN SEGUN UN PROCESO EN QUE, EN AUSENCIA DE UN SOLVENTE ORGANICO, SE ALIMENTA CLORURO DE ACIDO CARBOXILICO, MEZCLANDO INTENSAMENTE, EN UN RECIPIENTE DE TRIETILAMINA A UNA VELOCIDAD NO SUPERIOR A 3 MOLES/HORA POR MOL DE LA TRIETILAMINA PRESENTE Y LA MEZCLA, ALIMENTACION E INTERCAMBIO DE CALOR SE LLEVAN DE UNA MANERA TAN ARMONIZADA ENTRE SI QUE LA VISCOSIDAD DE LA MEZCLA SIEMPRE ES MENOR DE 250 MPA.S, MEDIDA A 60 (GRADOS) C (VELOCIDAD DEL ESFUERZO CORTANTE SUPERIOR A 100 L/SEG) Y LA RELACION MOLAR DE LA CANTIDAD TOTAL DE ACIDO CARBOXILICO ALIMENTANDO RESPECTO A LA CANTIDAD DE AMINA EN EL RECIPIENTE ES DE 1 : 1,025 A 1 : 2 Y DESPUES DE LA CONVERSION LA MEZCLA DE REACCION SE TRATA CON UN ACIDO HIDROCLORICO ACUOSO, DILUIDO O CON UNA SOLUCION ACUOSA DE HIDROCLORURO DE TRIETILAMINA Y ACIDO HIDROCLORICO Y SE SEPARA EL DIMERO DE CETENA. LAS CETENAS SON MUY ADECUADAS PARA UTILIZARLAS EN EL DIMENSIONAMIENTO DE PAPEL.
