Research on Synthesis Process of BHPF Catalyzed by Thiohydracrylic Acid

The new synthesis process of bisphenol fluorene(BHPF)with thiohydracrylic acid as catalyst was introduced in this paper.The mol ratio between phenol and fluorene,reaction time,temperature,catalyst consumption were investigated.The optimized process conditions were as follows:when the amount of fluorenone is set to be 0.5 mol,the mol ratio between phenol and fluorenone is 5:1,consumption of thiohydracrylic acid 18 g and maintained at 80°C for 5 hrs.Under such conditions the yield of BHPF can be as high as 93.4% with purity over 99.3%.The structure and characterization of the produce was also analyzed.
