Title: Solvent-free Synthesis of 2,4,6-Tri(O,O-dimethyphosphoryl)-1,3,5-triazine
Abstract: A phosphorus-containing triazine was synthesized from trimethyl phosphite and cyanuric chloride.The chemical structures of the product was characterized by means of()~1H NMR,FT IR and TG.The optimal conditions for preparation of 2,4,6-tri(O,O-dimethyphosphoryl)-1,3,5-triazine were as follows: dropping addition of trimethyl phosphite at room temperature,n(trimethl phospite):n(cyanuric chloride)=3.2∶1,reaction at 70 ℃ for 4 h.The yield was 91.3%.The product with high thermal stability can be used as a intumescent flame retardant.
