由阾-羟甲基苯酚和亚磷酸三烷基酯容易地得到膦酰基甲基取代酚。结合到酚-醛树脂上的游离酸,起着一种对不同金属离子具有奇特的选择性的阳离子交换剂的作用。
Phosphonomethyl-substituted phenol is readily obtained from limonene-hydroxymethylphenol and trialkylphosphite. The free acid bound to the phenol-aldehyde resin acts as a cation exchanger with a unique selectivity for different metal ions.
