4,4' -dihydroxy-diphenyl sulphone(BPS) was synthesized with phenol and sulturic acid as the mw materials, using benzene as water-moving agent. And the properties of the product were characterized by IR and XRD. Meanwhile, the influences of reactant ratio and reaction temperature on the product yield were discussed.The experiment results indicated that the product yield could reach 86％ after the purification with the reactant temperature was 160 ℃ and the reactant mole ratio of sulfuric acid to phenol was 0.6：1.%本文以苯酚和98%浓H2SO4为原料,苯为除水剂合成了显色剂4,4'-二羟基二苯砜(BPS),并利用FTIR、XRD等分析手段对产品性能进行了表征.同时,探讨了反应物配比和反应温度等条件对BPS产率的影响.实验表明:在160℃反应条件下,H2SO4与苯酚摩尔比为0.6:1时,合成产物经精制后产率达86%.
