Phosphonium salt formula
WebThe phosphonium structure is converted to phosphine oxide as the result of this reaction. [5] [P (CH 2 OH) 4 ]Cl + NH 2 CONH 2 → (HOCH 2) 2 POCH 2 NHCONH 2 + HCl + HCHO + H 2 + H 2 O This reaction proceeds rapidly, forming insoluble high molecular weight polymers. The resulting product is applied to the fabrics in a "pad-dry process."
