扁桃酸

The HPW/M-SiO2 catalyst is characterized by means of infrared-ray spectrum, X-ray diffraction and n-C4H9NH2 Potentiometric titration. The effects of amount of the catalyst, molar ratio of acid and alcohol, reaction temperature and reaction time on synthesis of methyl mandelate have been investigated.

运用IR， XRD和n-C4H9NH2电位滴定法测试技术表征HPW/M-SiO2催化剂，考察了催化剂用量、物料配比、反应温度和反应时间等对扁桃酸甲酯合成的影响。
