Abstract
At present, tetra-hydroxymethyl phosphonium chloride (THPC) is widely used in flame retardant finishing, industrial water treatment and leather manufacture industry etc., and its decomposition which was caused by pH changing will influence on the actual application. So acid-alkali decomposition of THPC was studied by 31P Nuclear Magnetism Resomance (31P NMR), spectrophotometry and titration respectively. The results show that THPC solution is stable when pH9.0, all of the phosphorus compounds converts to TrHPO. Consequently, THPC content decreases when pH of the THPC solution rising, which could give a favorable guide in THPC application.
