Styrenated phenols are usually synthesized by the reaction of styrene and phenol under acid catalysts. Styrenated phenol involving high content of di-styrenated phenol (DSP) was synthesized, which can be used to prepare styrenated phenol alkoxylate. The solid catalyst used in this study was prepared by impregnation method. SO4 2- on SO4 2-/ZrO2 catalyst was introduced from an aqueous 1M-H2SO4 solution. The catalysts were characterized by SEM images, XRD patterns, and FT-IR spectra. The catalytic activity was examined by measuring the conversion of phenol and styrene in a liquid-phase batch reactor. Almost 100% conversion of both phenol and styrene over 15-SO4 2-/ZrO2 catalyst were obtained at reaction temperature of 100 °C and reaction time of 6 hr. Amount of catalyst to the reactants was 15 wt%. At same reaction conditions, selectivity of MSP, DSP, and TSP were 23.6%, 52.1%, and 5.4%, respectively. It was known that the selectivity to DSP was increased as IR absorption peak of 1236 cm-1 corresponding to O–S–O bonds was increased.
苯乙烯化苯酚通常是在酸催化剂作用下通过苯乙烯与苯酚反应合成的。合成了含有高含量二苯乙烯化苯酚（DSP）的苯乙烯化苯酚，其可用于制备苯乙烯化苯酚烷氧基化物。本研究中使用的固体催化剂通过浸渍法制备。SO4 2-/ZrO2催化剂上的SO4 2-是从1M硫酸水溶液中引入的。通过扫描电子显微镜（SEM）图像、X射线衍射（XRD）图谱和傅里叶变换红外光谱（FT-IR）对催化剂进行了表征。在液相间歇反应器中通过测量苯酚和苯乙烯的转化率来考察催化活性。在反应温度为100℃、反应时间为6小时的条件下，15%-SO4 2-/ZrO2催化剂上苯酚和苯乙烯的转化率几乎均达到100%。催化剂与反应物的用量比为15wt%。在相同反应条件下，间苯乙烯化苯酚（MSP）、二苯乙烯化苯酚（DSP）和三苯乙烯化苯酚（TSP）的选择性分别为23.6%、52.1%和5.4%。已知随着对应于O–S–O键的1236 cm-1处红外吸收峰增加，DSP的选择性提高。
