Abstract

The invention discloses a method for synthesizing bisphenol F from phenol and formaldehyde with a phosphotungstic acid modified metal organic frame catalyst. In the method, through selection of different metal source and modification amount of phosphotungstic acid, the phosphotungstic acid modified metal organic frame catalyst is prepared in a one-step manner. The catalyst is simple in preparation method, is convenient to separate and recycle and can be reused and is free of corrosion to devices. When being used for catalyzing the phenol and the formaldehyde to synthesizing the bisphenol F, the catalyst can regulating distributions of three isomers of a product of the bisphenol F. The invention provides a new method for catalytically synthesizing the bisphenol F.

Description

technical field

[0001] A kind of method that phosphotungstic acid modified metal-organic framework catalyzes the synthesis of bisphenol F Background technique

[0002] Bisphenol F, also known as dihydroxydiphenylmethane, has three isomers of 2,2'-, 2,4'- and 4,4'-dihydroxydiphenylmethane, which can be used to prepare low Viscosity modifier for epoxy and phenolic resins. Due to its chemical structure characteristics, the performance of the finished epoxy resin synthesized with bisphenol F is better than that of bisphenol A in many aspects, especially its characteristics of easy injection and casting flow, and can add less or even no diluent, which is especially suitable for The processing and molding of epoxy resin for large wind power blades also greatly reduces environmental pollution and improves the processing environment.

[0003] Few of the reported methods for the synthesis of bisphenol F involve the distribution of bisphenol F isomers. Patent JP6340565 introduces t...
