Sodium hypophosphite (NaPO 2 H 2, also known as sodium phosphinate) is the sodium salt of hypophosphorous acid and is often encountered as the monohydrate, NaPO 2 H 2 ·H 2 O. It is a solid at room temperature, appearing as odorless white crystals. It is soluble in water, and easily absorbs moisture from the air.

Hypophosphite, also known as phosphonate, is an ion. Its chemical formula is H 2 PO 2-. It contains phosphorus in its +1 oxidation state. It is made by disproportionation of phosphorus in warm alkali. Phosphine is also produced. It is a strong reducing agent. Chemical compounds that contain the hypophosphite ions are called hypophosphites.

Phosphinates or hypophosphites are a class of phosphorus compounds conceptually based on the structure of hypophosphorous acid. IUPAC prefers the term phosphinate in all cases, however in practice hypophosphite is usually used to describe inorganic species (e.g. sodium hypophosphite), while phosphinate typically refers to organophosphorus species.

Hypophosphite is a type of ion (H2PO2-) that can act as a ligand in certain materials. It exhibits unique structural properties different from formate ions, including various configurations and off-centering of organic cations in frameworks.

详细研究了以黄磷、氧化钙和碳酸钠为原料，采用一步法制备次磷酸钠的最佳条件和有关工艺。 [1] hypophosphite，英语单词，主要用作为名词，意为 [无化] 次磷酸盐。

1990年6月1日 · Sodium hypophosphite has good potential as an antimicrobial food ingredient and it is Generally Recognized As Safe (GRAS). This review summarizes SHP chemistry, history, toxicology, regulatory status, applications, and antimicrobial properties.

Sodium hypophosphite decomposes when heated, forming phosphine, a spontaneously flammable gas.

Free hypophosphorous acid, H 3 PO 2, is prepared by acidifying aqueous solutions of hypophosphite ions, H 2 PO 2−. For example, the solution remaining when phosphine is prepared from the reaction of white phosphorus and a base contains the H 2 PO 2− ion. If barium hydroxide (BaOH) is used as…
