Abstract
9,9-Bis (4-hydroxyphenyl) fluorene is synthesized with heteropoly acid instead of inorganic acid as the catalyst, which has great significance for environmental protection. In this experiment, the synthesis of 9,9-bis (4-hydroxyphenyl) fluorene is studied by using fluorenone and phenol as raw materials, using homemade heteropoly acid 11-tungsten-titanium titanium (molecular formula H4Ti(H2O)TiW11O39) as the catalyst and 3-mercaptopropionic acid as the cocatalyst. The structure of the catalyst was characterized. The effect of the molar ratio of raw material, reaction temperature, reaction time, and the dosage of catalyst and cocatalyst on the purity and yield of 9,9-bis(4-hydroxyphenyl) fluorene are investigated, and the best reaction conditions are obtained. The results show that the new catalyst has a good catalytic effect, and the product has good quality and a high yield.
