摘要
在氢氟酸溶液中,混合亚磷酸、4,4’-联苯二膦酸和锆离子反应生成4,4’-联苯二膦酸锆/亚磷酸锆(简称MCZP),改变有机酸和亚磷酸的比例,可以合成具有相同组分但结构不同的一系列化合物。通过磺化反应,在苯环上接上磺酸基团后,它具有类似强酸性阳离子交换树脂特性.该文首次对这类化合物催化酯化、醚化等典型的酸催化有机反应进行了研究,结果表明其催化转化率高、催化剂可重复使用和再生,是一种很有发展前途的新型固体酸催化剂.
A series of mixed component zirconium phosphite/4, 4'-diphenyl bisphosphate (MZCP) are synthesized with ZrOC128H2O and a mixture of phosphorous acid and 4, 4'-diphenyl bisphosphoric acid.They have catalytic activity when the phenyl groups in MCZP are sulfonate. Some organic reactions such as esterfication,acetal formation and preparation of alklene by alcohol dehydration have been studied via using the catalyst.
