The dark green bis-anion obtained from treatment of 10-hydroxy-5, 10-dihydrophenophosphazine 10-oxide with NaH reacted with MeI at about 120℃ in anhydrous DMF to give N-methyl phosphinic acid.

在无水DMF中，用NaH处理5，10-二氢磷杂吖嗪环系次膦酸，得到黯绿色双负离子钠盐，该钠盐与MeI在约120℃下反应，得到N-甲基-5，10-二氢磷杂吖嗪环系次膦酸。

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。

Monododecylphosphate was prepared by esterification of lauryl alcohol with phosphoric acid(mass fraction 85%) on cesium phosphotungstate catalyst.
