技术领域
背景技术
碳酸二苯酯(DPC)是一种用途十分广泛的有机碳酸酯,可用来合成许多有机中间体。DPC本身无毒、无污染,是一种重要的绿色环保化工产品,可通过卤化、硝化、水解、氨解等反应来合成许多有机化合物和高分子材料,如单异氰酸酯、二异氰酸酯、聚碳酸酯、聚对羟基苯甲酸酯、聚芳基碳酸酯等。还可以作为聚酰胺和聚酯的增塑剂、高沸点有机溶剂和载热体等。近年来,随着环境友好的以DPC和双酚A为原料合成高品质的聚碳酸酯新工艺的开发,使DPC成为特别引人注目的化合物。
合成DPC传统的方法以光气和苯酚为原料,在碱性介质中进行反应,如CN8610765所公开的方法。但光气有剧毒且腐蚀性大,安全及环境问题突出,而且所生产的DPC中会残留氯离子,影响了由该碳酸二苯酯与双酚A反应所得的聚碳酸酯的质量。因此采用非光气法合成DPC备受关注,在非光气法合成DPC的制备方法中,目前研究的重点是氧化羰基化法和酯交换法。
氧化羰基化法以苯酚、一氧化碳、氧气为原料,在催化剂作用下反应生成碳酸二苯酯。该工艺具有无污染、不需溶剂、无有毒盐生成的优点,但是由于催化剂体系比较复杂,包括主催化剂、助催化剂和助剂等,而且活性较低,同时反应生成的水难于除去。如在EP0350700中,反应5小时苯酚转化率仅为14%,加入一定量的3A分子筛以除水,5小时后转化率升至34%。Ho Young Song等[Journal of Molecular Catalysis A:Chemical 154,2000,243~250]开发的羰基钯催化剂在300K下反应7小时,苯酚的转化率为30%,DPC产率为21.1%。CN1391985公开了用负载型Cu(OAc)2/沸石作为催化剂,碳酸二苯酯的收率为14.2%。CN1391986进一步改进催化剂,用双组分负载型PdCl2-Cu(OAc)2/沸石作为催化剂,碳酸二苯酯的收率也才提高到53.7%。
为此,国内外研究者又开发了苯酚和碳酸二甲酯(DMC)为原料直接合成碳酸二苯酯的酯交换工艺路线。
目前苯酚与碳酸二甲酯在催化剂下的酯交换反应是唯一工业化的非光气合成路线。该方法有两种工艺路径可以选择,一种是一步法,在一个反应器中碳酸二甲酯和苯酚通过酯交换反应直接合成,产物中包括碳酸二苯酯、碳酸苯甲酯(或称甲基苯基碳酸酯)以及苯甲醚等,再通过进一步分离得到碳酸二苯酯;另一种方法是两步法,即碳酸二甲酯和苯酚先酯交换反应得到中间体碳酸苯甲酯,然后把中间体碳酸苯甲酯分馏出来单独进行歧化反应,或再次与苯酚酯交换反应,得到碳酸二苯酯。目前,该工艺已开发出了有机锡化合物、茂钛类络合物、钛酸酯类化合物等新型催化剂,使碳酸二苯酯的收率有所提高。但由于碳酸二甲酯的羰基化反应活性低于光气,能产生副产物苯甲醚,因此能否开发出高转化率、高选择性的催化剂是该路线的关键。现有催化剂体系主要有多相催化剂和均相催化剂两种,多相催化剂具有催化剂容易分离的特点,但存在催化剂活性差、苯酚转化率低,产物选择性差等缺点,如CN1803282采用了钒-铜的复合氧化物作为催化剂,碳酸二苯酯的收率为30%。CN1915504采用了钼-铜的复合氧化物作为催化剂,碳酸二苯酯的收率达到了40.6%;在CN1128664中,采用了PbO-ZnO的复合金属氧化物作为催化剂,碳酸二苯酯的收率达到了45.6%,但酯交换选择性只有72%。在CN101905155A中,采用了钼-钛复合氧化物为催化剂,酯交换总选择性也只达到96%左右。均相催化剂的活性较高,但存在催化剂与产物分离困难、催化剂不稳定等缺点。在高俊杰等人的论文中(催化学报,2001,22(4):405-407),采用了钛酸丁酯和钛酸苯酯作为催化剂,催化苯酚和碳酸二甲酯的反应,但苯酚的转化率小于30%,而且钛酸酯类的稳定性较差,在空气中易吸湿潮解,生成TiO2,在工业应用中收到了一定的限制。
综上所述,研究开发高活性、高选择性和高稳定性的催化剂是提高碳酸苯甲酯或碳酸二苯酯生产效率的关键。
