Synthesis of triphenyl phosphite
The process of to synthesizing triphenyl phosphite by phenyol and phosphorus trichloride is studied. The optimized conditions are determined by orthogonal design method. When the molar ratio of n(phenyol):n(phosphorus trichloride) is 3.15:1, droping time of phosphorus trich loride is 2 h, agitation is quick, and reaction temperature is 60～(70 ℃), the yield of triphenyl phosphite can reach 84%～86%.
