The smaller the electronegativity is, the higher oxidation activity is. Thus phosphomolybdic acid shows better catalytic oxidation activity than phosphotungstic acid.

由于磷钨酸中的钨可以脱出并少量沉积到催化剂表面，而且从电负性来说Mo-O的键能小于W-O，键能小的杂多酸有较强的氧化性，所以钼系杂多酸催化活性要好于钨系杂多酸。

Highly ordered SBA-15 sieves have been successfully synthesized in a low concentration liquid inorganic acid medium via the addition of small amounts of phosphomolybdic acid.

通过在低浓度无机液体酸介质中添加少量磷钼酸，成功地合成了高度有序的SBA-15介孔分子筛。N2吸附-脱附、XRD、TEM和水热稳定性实验等检测结果表明：用这种方法不仅可以大幅度降低合成SBA-15分子筛所需液体酸的用量和缩短晶化时间，同时反应产物SBA-15在100℃的水中处理72h后仍然保持六方有序的介孔结构

Also the performance of this modified electrode was compared with sodium molybdate modified platinum electrode. The cyclic voltammetry tests show that phosphomolybdic acid modified platinum electrode can increase the catalytic activity for methanol oxidation and it is almost the same as the mono-molybdate (Na2MoO4) modified Pt electrode does. This promote effect mainly comes from the transformation of different valency of molybdenum.

通过循环伏安和计时电流法研究了该修饰电极对甲醇氧化的电催化活性和抗中间产物的毒化作用，并比较了该修饰电极与其单酸盐(Na2MoO4)修饰铂电极的性能，测试结果表明：磷钼酸修饰铂电极能够提高对甲醇氧化反应的催化活性，基本上同其单酸盐Na2MoO4修饰铂电极的催化活性相当，并且这种促进作用主要是由Mo原子价态变化引起的。

This paper reports the study for phosphomolybdic acid H 3[P(Mo 3O 10 4]·xH 2O as catalyst and anhydrous magnesium sulfate as drying agent used in the esterification of hexanoic acid and ethyl alcohol.

报道了以磷钼酸为催化剂，以无水硫酸镁为吸水剂，催化脱水合成己酸乙酯。

Phosphomolybdic acid solution;dodecamolybdophosphoric;dodecamolybdophosphoric acid;dodecamolybdophosphoricacid

性能： 黄色发光的棱形晶体。溶于水、乙醚和乙醇。主要用作分析试剂，也用于制颜料等。由三氧化钼直接与磷酸溶液作用而制得。

钼-氯酸盐体系的催化极谱的研究——II。

In polymolybdate, the initial raw materials's reducing vulnerability and the related intermediate products in the reaction are prerequisite for the growth of crystal.

在多钼酸盐中，分子生长的先决条件是初始原料的易还原性以及在反应混合物中相关中间产物。

Ascorbic acid, ammoniun rhodanate and methyl isobutyl ketone are used to extract Mo form soil sample solution for the purpose of removing matrix interferences.

研完了水相酸度，各试剂用量，不同有机溶剂以及共存干扰离子对萃取和测定的影响，无须去掉水相直接测定有机相中的钼。

Mammography showed multiple serpiginous, tubular calcifications, which are characteristic of calcified filariasis, in both breasts.

钼靶显示双侧乳腺多个匍匐状，管状钙化，具备丝虫钙化的特征。
