Traditionally benzylation of phenol is carried out with benzyl chloride which is corrosive and difficult to handle, and the resultant reaction is not atom economical. Benzyl alcohol is an alternative to benzyl chloride which is safe and easy to handle. Benzyl phenols are industrially important products particularly in plastic, rubber and petroleum industries. In present study, cesium salt of dodecatungstophosphoric acid (Cs_2.5H_0.5PW₁₂O₄₀, Cs-DTP) supported on mesocellular foam (MCF) silica was used as catalyst among others. The activity of prepared catalyst, 20% (w/w) Cs-DTP/MCF was compared with Amberlyst-15, montmorillonite clay K10, S-ZrO₂ and unsupported Cs-DTP catalyst. The supported catalyst showed better performance because of even distribution of acidic sites on MCF. The effect of reaction parameters were studied in detail and it was found that reaction follows second order kinetics. The activation energy was found to be 15.94 kcal/mol. The catalyst was found reusable.

传统上，苯酚的苄基化是用苄基氯进行的，该苄基氯具有腐蚀性且难以处理，并且所得反应在原子上也不经济。苄醇是安全且易于处理的苄基氯的替代物。苄基酚是工业上重要的产品，特别是在塑料，橡胶和石油工业中。在本研究中，十二烷基磷酸二氢铯盐（Cs _2.5 H _0.5 PW ₁₂ O ₄₀，Cs-DTP）负载在介孔泡沫（MCF）二氧化硅上用作催化剂。将制备的催化剂20％（w / w）Cs-DTP / MCF的活性与Amberlyst-15，蒙脱土K10，S-ZrO _{2进行比较}和不支持的Cs-DTP催化剂。负载的催化剂表现出更好的性能，因为酸性位在MCF上均匀分布。详细研究了反应参数的影响，发现反应遵循二级动力学。发现活化能为15.94kcal / mol。发现该催化剂可重复使用。
