摘要:
以N,N-二甲基甲酰胺(DMF)和N,N-二甲基乙酰胺为主溶剂(DMAC)、环糊精(CD)为助剂,复配获得萃取剂DMF+CD(DMFM)和DMAC+CD(DMCM),同时以正己烷和环己烷模拟链/环烷烃混合物,实验测定了常压和283.15~303.15 K下正己烷+环己烷+DMFM和+DMCM液液相平衡(LLE)数据。借助分配系数和选择性,评价了两种复配萃取剂对链/环烷烃混合物的分离效果,并进一步实验测定了复配溶剂的黏度以考察其流动性。结果表明:复配萃取剂对环己烷的选择性随萃取剂中CD含量增加而增加,且选择性DMFM<DMCM,分配系数DMFM<DMCM;复配萃取剂的黏度同样随CD含量增加而增大,且DMCM>DMFM;实验LLE和混合物黏度数据分别由NRTL和VTF模型进行关联,获得了新的模型参数。研究结果可为石脑油中链/环烷烃分离及过程设计提供基础数据及理论支撑。
