Abstract

MéTODO DE PREPARAçãO DE LìQUIDOS IÈNICOS ISENTOS DE HALOGENETOS E LìQUIDOS INÈNICOS ASSIM PREPARADOS A reação de N-alquil-imidazol com sulfonatos de alquila, na temperatura ambiente, propicia alcano-sulfonatos de 1,3-dialquil imidazólio como sólidos cristalinos em altos rendimentos. Os ânions alcano- sulfonatos podem ser facilmente substituídos por uma série de outros anions (BF~4~, PF~6~, PF~3~(CF~2~CF~3~)~3~, CF~3~SO~3~ e (CF~3~SO~2~)~2~N! mediante simples reação de ânions, sais, ou ácidos em água na temperatura ambiente. A extração com diclorometano, filtração, e a evaporação do solvente, propiciam os desejados líquidos iónicos em rendimento de 80-95%. A pureza desses líquidos iónicos (em alguns casos >99,4%) pode ser determinada pela intensidade dos sinais de satélites ¬13¬C dos espectros de ressonância magnética do grupo N-metil imidazólio como um padrão interno.
