Technology Process of Trimetaphosphoric acid

There total 4 articles about Trimetaphosphoric 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:

phosphonic Acid (13598-36-2) + bromine (7726-95-6) → hydrogen bromide (10035-10-6,12258-64-9) + pyrophosphoric acid (14000-31-8,2466-09-3) + tetrametaphosphoric acid (13598-74-8) + trimetaphosphoric acid (13566-25-1)

Guidance literature:

In neat (no solvent); byproducts: polyphosphoric acid; react. of anhydrous H3PO3 with liquid Br2 on heating; formation of HBr, (HPO3)4, (HPO3)3, H4P2O7 and higher polyphosphoric acids; exothermic react. starting at ambient temp. after an induction period;;

Reference yield:

phosphorous pentoxide → phosphoric acid (86119-84-8,7664-38-2) + pyrophosphoric acid (14000-31-8,2466-09-3) + trimetaphosphoric acid (13566-25-1)

Guidance literature:

With water; In water; hydrolysis; formation of polymer phosphoric acids and a small amont of H3PO4, H4P2O7 and H3P3O9;; products detected by paper chromatography, not isolated;;

Reference yield:

M-P2O5 (monomeric P4O10) (16752-60-6) → iso-tetrametaphosphoric acid (50859-16-0) + phosphoric acid (86119-84-8,7664-38-2) + triphosphoric acid (10380-08-2) + tetrametaphosphoric acid (13598-74-8) + trimetaphosphoric acid (13566-25-1)

Guidance literature:

With water; In water; byproducts: H4P2O7; hydrolysis; a soln. prepared at 0 °C contains after 2 h tetrametaphosphoric acid H4P4O12, triphosphoric acid H5P3O10, H3PO4, trimetaphsophoric acid H3P3O9, H4P2O7, polymer phosphoric acids and a small amount of iso-tetrametaphosphoric acid;; compounds detected by paper chromatography; content after 2 h: 75 % H4P4O12, 15 % H5P3O10, 5 % H3PO4, 2-3 % H3P3O9, 3 % polymer phosphoric acids and 2 % H4P2O7;;
