Phosphinic acid Use and Manufacturing
Used in the formulation of pharmaceuticals, discoloration of polymers, water treatment, retrieval of precious or non-ferrous metals. Its main use is for electrodless plating. 1. Used as a reducing agent for electroless plating; 2. Used to prevent the discoloration of phosphoric acid resin; 3. Used as a catalyst and refrigerant for esterification; 4. Used to make hypophosphite, its sodium salt, manganese salt, iron salt, etc. are usually used as tonic drugs; 5. Used in medicine and as a reducing agent, as a reagent for the determination of arsenic and tellurium and the separation of tantalum and niobium.
