催化劑分離、回收與再生

內容概要

　　本書提出了新的辦法來解決從均相催化中分離反應產物的難題。新流程涉及低浸出負載型催化劑，可溶性支持措施，如聚合物和樹枝狀大分子，不常用的溶劑，例如水，含氟有機物，離子液體和超臨界流體。不同于其他書籍，除了所涉及的化學，本書著眼于流程的設計，并與現有流程進行了比較，并給出了實例。內容主要包括：新工藝分離的產品解決方案，含有均相催化劑；催化劑對不溶性或可溶性支持-固定床催化劑-連續(xù)流或超濾；雙相系統(tǒng)：水-有機氟-有機液體，離子液體-有機液體，超臨界流體（單相或雙相與水，有機或離子液體）；對比當前的流程，涉及大氣或低溫蒸餾；考察化學與工藝設計；每種方案的利弊等?！　”緯晒┐呋瘜W專業(yè)研究生，化工、醫(yī)藥工業(yè)科研人員參考使用。
