产品应用： 羟乙二磷酸一水合物又称1-羟基亚乙基二膦酸，是一种有机膦酸，可用于表面官能化NaY分子筛。HEDP/NaY可作为酯化法生产正乙酸丁酯的催化剂。 它还可在金属-配体配合物的合成中用作螯合剂。 Product Application: Etidronic acid monohydrate also known as 1-hydroxyethylidenediphosphonic acid (HEDP) is an organophosphonic acid that can be used to surface functionalize NaY molecular sieves. HEDP/NaY can be used as a catalyst for n-butyl acetate production via esterification. It can be also employed as a chelating agent in the synthesis of metal-ligand complexes.
