C102大孔强酸性阳离子交换树脂催化剂的制备与应用

Preparation and Application of C102 Macroporous Strongly Acidic Cation Exchange Resin Catalyst

以ＮＢ－ １ 型弱极性溶剂为致孔剂合成的ＳＴ－ ＤＶＢ 共聚体为骨架，经氯化、磺化制得Ｃ１０２ 大孔阳离子交换树脂。在绝热反应器中将其用作壬烯与苯酚的烷基化反应催化剂，在空速９ ｈ － １ 、反应温度８８ ～１３０ ℃的条件下，６００ ｈ连续反应后壬烯转化率≥９４ ％ ，壬基酚选择性达９５ ％ ；在等温反应器中用作二甘醇分子内脱水环化反应的催化剂，在空速为０－４ ｈ － １ 、平均床温１５５ ℃下，连续反应３８０ ｈ 后二甘醇的单程转化率≥６２－９ ％ 。

The authors reported the synthesis of C102 macroporous cation exchange resin from ST-DVB copolymer via chlorination and sulfonation,with NB-1 weak polar solvent as pore formation agent.The resin was used as a catalyst for the alkylation reaction of nonylene and phenol in an adiabatic reactor.Under the conditions of space velocity 9 h -1 ,reaction temperature,88～130 ℃ and reaction time,600 h,the conversion of nonylene is over 94% and the selectivity of nonyl phenol is over 95%.The resin was used as catalyst for the cyclization reaction of diethylene glycol intramolecular dehydration in an isothermal reactor.Under the conditions of space velocity,0 4 h -1 ,average bed temperature,155 ℃ and reaction time,380 h,the per pass conversion is over 62 9%
