phosphotungstic acid meaning in English
磷钨酸
Examples
- Study on the photochromism of phosphotungstic acid polyviny pyrrolidone nanocomposite films
聚乙烯基吡咯烷酮纳米复合膜的光致变色性能 - Synthesis of benzaldehyde dihexyl mercaptal catalyzed by phosphotungstic acid immobilized on ion exchange resin
树脂固载磷钨酸催化合成苯甲醛正己硫醇缩醛 - Activity of the phase transition oxidation catalyst prepared by phosphotungstic acid - metal salt composite and its optimum reaction condition
杂多金属盐制备相转移催化氧化剂的活性及其优化反应条件 - Using the phosphotungstic acid immobilized on active carbon as catalyst , the iso - amyl gallate was synthesized directly by esterifying isoamyl alcohol and gallic acid
摘要以活性炭固载磷钨酸作为催化剂，用没食子酸与异戊醇直接酯化合成了没食子酸异戊酯。 - Because the tungsten from the phosphotungstic acid could pull out and deposit on the surface of catalyst , and the electronegativity of mo - o is smaller than that of w - o . 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。
