新型二茂铁甲基季铵盐离子液体的合成与表征

Synthesis and characterization of a novel ionic liquid of (ferrocenylmethyl) trimethyl quaternary ammonium salt

以二茂铁与二甲胺为原料合成了碘化二茂铁甲基季铵盐,再经复分解反应得到乙酸二茂铁甲基季铵盐离子液体;表征了离子液体的结构,测定了其熔点和溶解性.结果表明,合成的乙酸二茂铁甲基季铵盐离子化合物熔点低于100℃,是一种新型的二茂铁甲基季铵盐离子液体.

Iodinated（ferrocenylmethyl）trimethyl quaternary ammonium salt was synthesized by using ferrocene and dimethylamine as the starting materials.Resultant iodinated（ferrocenylmethyl）trimethyl quaternary ammonium salt was then allowed to take part in metathetical reaction,yielding acetic acetate（ferrocenylmethyl）trimethyl quaternary ammonium salt as an ionic liquid.The structure of the ionic liquid was characterized,and its melting point and solubility were measured.It has been found that as-synthesized ionic liquid has a melting point of below 100 ℃,belonging to a novel room temperature ionic liquid.
