Condensed methyl phosphates. Separation by molecular distillation
Pentamethyl triphosphate and hexamethyl tetraphosphate were isolated with small amounts of analogous polymers as by-products. It was found that the triphosphate reorganized to form the tetraphosphate and diphosphate esters with an apparent second-order reaction rate having an approximate half-life of 1.00 × 107 sec.
