Preparation and properties of 9,9-bis(methoxymethyl)fluorene

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(hydroxy-methyl) 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 the three-phase transfer catalysis method.The Ziegler-Natta catalyst is prepared by 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-bis(methoxymethyl) fluorene.
