一般描述

Ammonium phosphate dibasic is a water-soluble ammonium phosphate salt. It is a key component of phosphate fertilizers. It is commonly used as a flame retardant for plywood, paper, and fabrics, as well as a corrosion inhibitor consolidant for degraded carbonatic materials found in old buildings.

应用

磷酸二酸铵可作为催化剂用于:
  • 通过三组分缩合反应合成四氢苯并[b]芘衍生物。
  • 无溶剂 Biginelli 反应。
  • 通过吲哚衍生物与芳香或脂肪醛的无溶剂反应合成吲哚基甲烷。
