钨锗酸催化苯乙烯与福尔马林的Prins反应研究

Study on the Prins Reaction of Styrene with Formalin Catalyzed by Tungstogermanic Acid

研究了以钨锗酸为催化剂的苯乙烯与福尔马林的液相Ｐｒｉｎｓ反应。考察了催化剂用量、物料配比及反应时间的影响。得到了该反应的适宜条件，在此条件下，福尔马林的转化率可达５４．５％。

Tungstogermanic acid has ben studied as catalyst for the Prins reaction of atyrene with formalin in liquid phase. Effects of the amount of the catalyst used,the reaction time and the ratio of reactants were investigated. The suitable condition of the reaction was obtained. Under the condition,the conversion of formalin could reach 54. 4%.
