Technology Process of Hypophosphoric acid

There total 26 articles about Hypophosphoric acid which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 42.0%

phosphorous → phosphonic Acid (13598-36-2) + phosphoric acid (86119-84-8,7664-38-2) + hypophosphorous acid (6303-21-5) + hypophosphoric acid (7803-60-3)

Guidance literature:

With sodium chlorite; In not given; a soln. of sodium chlorite is converting 42% of the red P into H4P2O6;;

DOI:10.1021/ja01175a041

Reference yield:

I(x)O(x)P(x) → phosphonic Acid (13598-36-2) + phosphoric acid (86119-84-8,7664-38-2) + hydrogen iodide (10034-85-2) + hypophosphoric acid (7803-60-3)

Guidance literature:

With water; In water; byproducts: H4P2O5, PH3; easy hydrolysis;;

Reference yield:

diphosphorus tetraiodide (13455-00-0) + water (7732-18-5) → phosphonic Acid (13598-36-2) + subdiphosporous acid (20267-10-1) + phosphoric acid (86119-84-8,7664-38-2) + phosphan (7803-51-2) + hypophosphoric acid (7803-60-3)

Guidance literature:

In carbon disulfide; water; hydrolysis of a sol. of P2I4 in CS2 in acidic, neutral or alkaline soln.at 0°C leads to formation of small amt. of subdiphosporous acid;; sepn. as Ba-salt;;
