摘要
The synthesis, properties and flame retardation of two kinds of flame retardants, mono(1 chloride 2 hydroxy propyl) phosphate and antimony mono(1 chloride 2 hydroxy propyl)phosphate were reported. Mono(1 chloride 2 hydroxy propyl) phosphate was synthesized from epichlorohydrin and phosphoric acid at molar ratio of 1∶1.2 in the solvent of methyl benzene with AlCl 3 catalyst under the conditions of reaction temperature of 90 ℃ and reaction time of 2 h, its total yield is 82.5%. Antimony mono(1 chloride 2 hydroxy propyl)phosphate was synthesized from mono(1 chloride 2 hydroxy propyl)phosphate and antimony trioxide in the solvent of dimethyl sulfoxide with oxalic acid catalyst under the conditions of reaction temperature of 92 ℃ and reaction time of 4 h, the total yield is 85.6%. The physical chemical properties of the products were determined. When adding 15% of mono(1 chloride 2 hydroxy propyl) phosphate and antimony mono(1 chloride 2 hydroxy propyl)phosphate in polyethylene respectively, the oxygen indexes (OI) are 31.4 and 33.7 respectively.

The synthesis, properties and flame retardation of two kinds of flame retardants, mono(1-chloride-2-hydroxy propyl)phosphate and antimony mono( 1-chloride-2-hydroxy propyl)phosphate were reported. Mono(l-chloride2-hydroxy propyl) phosphate was synthesized from epichlorohydrin and phosphoric acid at molar ratio of 1:1.2 in the solvent of methyl benzene with AlCl3 catalyst under the conditions of reaction temperature of 90 degrees C and reaction time of 2 h, its total yield is 82.5%. Antimony mono( 1-chloride-2-hydroxy propyl)phosphate was synthesized from mono(l-chloride2-hydroxy propyl)phosphate and antimony trioxide in the solvent of dimethyl sulfoxide with oxalic acid catalyst under the conditions of reaction temperature of 92 degrees C and reaction time of 4 h, the total yield is 85.6 %. The physical-chemical properties of the products were determined. When adding 15% of mono( 1-chloride-2-hydroxy propyl) phosphate and antimony mono(1-chloride-2-hydroxy propyl)phosphate in polyethylene respectively, the oxygen indexes (OI) are 31.4 and 33.7 respectively.
