etherization
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，本文采用williamson合成法運用氯化芐( phch _ 2cl )使-環糊精( - cd )醚化，并由元素分析結果，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。
These years we have developed strongly acidic macroreticular catalysts based on styrene dvb . catalyst resin d006 for mtbe tame etbe , also as catalyst use for producing tba by isobutene hydration and direct producing gasoline with high octane rating by light gasoline etherification . d008 for sba ipa , also can be used for making methyl ethyl ketone by acetone one - stepping process , tert - butanol by isobutene hydration , etherified gasoline by the etherification of isopentene and isohexene in light gasoline with methyl alcohol , high 以上，增強了催化活性，從而延長了使用壽命，提高了周期產量二低溫活性好，選擇性強，提高了mtbe的純度，降低了雜質含量三在同樣裝置中，可增大負荷，提高產量，降低生產成本和費用。
