样品中三唑醇残留物由正己烷饱和的乙腈(含1%冰醋酸)提取，加入无水硫酸镁与无水醋酸钠振荡促使提取液分层后进行固相分散萃取净化，用气相色谱-负化学离子源质谱法进行测定与确证，外标法定量。

Nsted acid ionic liquids were inactive for the alkylation of isobutane with butene.In contrast,the chloroaluminate ioni c liquids were very active for the alkylation.However,the qualities of the alkylate oils using chloroaluminate ionic liquids were unsatisfied and worse than that of the products in the industrial sulfuric acid process obviously.
