  1. As to the separation of p - xylene / m - xylene, in order to blend polymer hydrophobe with p - cd which is preferential to adsorb p - xylene, etherified p - cd was synthesized using benzyl chloride ( phch2cl ). the influences of etherification conditions on the reaction conversion and the degree of substitution of etherified p - cd were investigated. the reaction conversion increases with the increasing of molar ratio of phcr ^ cl : p - cd and the concentration of p - cd

    對于px mx體系的分離，為使對px具有優先絡合能力的一環糊精（ cd ）能夠與油溶性高分子共混，本文採用williamson合成法運用氯化芐（ phch _ 2cl ）使-環糊精（ - cd ）醚化，並由元素分析結果，計算出醚化產物的取代度和轉化率，系統地考察了反應條件對轉化率和取代度的影響。
