摘　　要：研究9,9-双(甲氧甲基)芴的制备反应及其性能.9,9-双(甲氧甲基)芴的合成分两步:首先,芴与多聚甲醛反应合成9,9-双(羟甲基)芴;接着采用三相相转移催化法由9,9-双(羟甲基)芴制备9,9-双(甲氧甲基)芴.用9,9-双(甲氧甲基)芴做给电子体制备Ziegler-Natta催化剂催化丙烯聚合,催化剂的活性为每g催化剂催化130 kg丙烯,聚合物等规度为97%.提出一条清洁生产的工业合成工艺,并建立了生产装置,生产出了合格的9,9-双(甲氧甲基)芴.The preparation and properties of 9,9-bis （methoxymethyl） fluorene are studied. There are two steps in the synthesis of 9,9-bis（methoxymethyl） fluorene. Firstly, 9,9-bis（hydroxymethyl） fluorene is prepared through the reaction between fluorene and paraformaldehyde. Secondly, 9,9-bis（hydroxymethyl） fluorene is turned into 9,9-bis（methoxymethyl） fluorene with three-phase transfer catalysis method. The Ziegler-Natta catalyst is prepared by the 9, 9-bis（methoxymethyl） fluorene as electron donor. Propene is polymerized in good effect, the activity is 130 kg PP per g catalyst and the isotacticity of the polymer exceeded 97% with the Ziegler-Natta catalyst. A novel synthesis technology for producing 9,9-bis（methoxymethyl） fluorene is presented, and an equipment is also constructed successfully, which can manufacture high quality of 9, 9-his （methoxymethyl） fluorene.
