Preparation method of low-triphenyl phosphate engineering plastic halogen-free flame retardant

The invention belongs to the technical field of applied engineering plastics, and in particular, relates to a preparation method of a low-triphenyl phosphate engineering plastic halogen-free flame retardant. The method comprises the steps: under the action of a Lewis catalyst, carrying out a reaction of phenol with phosphorus oxychloride, reducing the pressure and distilling out excess phosphorusoxychloride, to obtain a mixture intermediate; carrying out a condensation reaction of the mixture intermediate and p-dihydroxybenzene, carrying out a reaction of the mixed intermediate with a properamount of p-dihydroxybenzene firstly, after a part of p-dihydroxybenzene is completely reacted, carrying out high vacuum dehydrochlorination, then adding triethylamine and the remaining p-dihydroxybenzene at relatively low temperature, and carrying out a reaction, wherein increase of the content of triphenyl phosphate is greatly reduced, toxicity to human bodies is reduced, and at the same time, the purity and the yield of the product are improved; and the preparation method has the advantages of simple process operation, short production cycle, economy and environmental protection, can satisfy the requirements of industrial scale production, and is suitable for industrialized popularization and application.

Catalytic synthesis of O-aryl methyl(phenyl)phosphonochloridates

The reaction of methyl- and phenyldichlorophosphonates with phenols in the presence of anhydrous magnesium chloride (catalyst) or magnesium metal (procatalyst) has been used as a simple, efficient, and industrially feasible method for the synthesis of the

(Diphenylphosphinoyl)oxyl: An Extremely Reactive Oxygen-Centered Radical

The title radical, Ph2P(O)O., has been generated by laser flash photolysis (LFP) of the peroxide 2 (1) in CH3CN solution.It has a broad, structureless absorption extending from 400 to beyond 800 nm.Absolute bimolecular rate constants k for its reactions with various organic substrates have been measured by LFP.It has been found that Ph2P(O)O. is more reactive in hydrogen abstraction (e.g., cyclohexane, k= 2.4x1E8 M-1s-1) and addition (e.g., benzene, k= 9.1x1E8 M-1s-1) than any other organic oxygen-centered radical.Only HO. is (generally) more reactive.Although Ph2P(O)O. could not be directly detected by EPR spectroscopy , it was successfully spin-trapped with a nitrone and with alkenes and alkynes.The formation of Ph2P(O)O. in the photodecomposition but not in the thermal decomposition of 1 is supported by 31P NMR analyses of reaction products.Semiempirical AM1-PM3 calculations on H2P(O)O. are also reported.
