Abstract

La reaccion de N-alquil-imidazol con sulfonatos de alquilo, a temperatura ambiente, propicia alcano-sulfonatos de 1,3-dialquil-imidazolio como solidos cristalinos en altos rendimientos. Los aniones alcano-sulfonatos pueden ser fácilmente sustituidos por una serie de otros aniones [BF4, PF6, PF3(CF2CF3)3, CF3SO3 y (CF3SO2)2N] mediante la simple reaccion de aniones, sales o ácidos en agua a temperatura ambiente. La extraccion con diclorometano, filtracion y evaporacion del solvente propician los líquidos anionicos deseados en un rendimiento de 80 a 95%. La pureza de estos líquidos ionicos (en algunos casos >99,4%) puede ser determinada por la intensidad de las senales de satélites 13C de los espectros de resonancia magnética del grupo N- metil-imidazolio como un patron interno. Reivindicacion 1: Procedimiento de preparacion de líquidos ionicos exentos de haluros, caracterizado porque comprende las siguientes etapas: i) alquilacion de 1-alquil C1-18-imidazoles con alcano C1-18 - sulfonatos de alquilo C1-18 o con trifluorometanosulfonato de alquilo C1-18; ii) reaccion de metátesis, en solucion acuosa, de los alcano C1-18 -sulfonatos de alquilo C1-18 con sales de metales alcalinos que contienen los aniones PF6, BF4, CF3SO3, (CF3SO2)2N, (CF3CF2)3PF3.
