Reagent pure phosphato-tungstic acid was prepared by reacting sodium tungstate with dis-odium hydrogen phosphate and acidifying with hydrochloric acid. 由钨酸钠与磷酸氢二钠反应，再经盐酸酸化制得了试剂级的磷钨酸。
The reaction of the synthesis of dibutyl adipate catalyzed by phosphotungstic acid supported on activated carbon was studied. 研究了用活性炭固载磷钨酸催化合成己二酸二丁酯的反应。
