Embodiment 1
[0043] Example 1、 Bisphenol A type polysulfate -1 with a degree of polymerization of 10~50 ( PSE-1 )Synthesis
[0044] (1) Synthesis of bisphenol A dioxysulfonyl fluoride: Dissolve 22.8 kg (100 mol) of bisphenol A (scientific name: 2,2-bis(4-hydroxyphenyl)propane) in 5 L of dichloromethane or chloroform Add 10.1 kg (100 mol) of triethylamine, and then carefully and continuously introduce sulfonyl fluoride gas. React at 25°C for 12 hours. After the reaction is complete, simply concentrate and filter to obtain 2,2-bis(4-oxysulfonyl fluorophenyl) propane as a white solid product of dioxysulfonyl fluoride (English) The full name is 4,4'-(propane-2,2-diyl)bis(4,1-phenylene) disulfofluoridate]) 38.5 kg, yield: 98%.
