Abstract:Mono(2-hydroxy propyl)phosphate was synthesized from 1, 2-epoxy propane and phosphoric acid in the propanone solvent under the conditions of reaction temperature 30 ℃, reaction time 2 h. The total yield of mono(2-hydroxy propyl) phosphate was 72%. Antimony mono(2-hydroxy propyl) phosphate was synthesized from mono(2-hydroxy propyl) phosphate and antimony trioxide in dimethyl sulfoxide solvent, the reaction time was 4 h. The total yield of antimony mono(2-hydroxy propyl) phosphate was 82%. These two kinds of products can be used as flame retardants.
Key words: antimony phosphate flame retardants
