Dibiphenol A pentaerythritol diphosphite was synthesized by using pentaerythritol,phosphorus trichloride and bisphenol A as raw material.The effects of reaction solvent,reaction time and molar ratio of the raw material on yields were analyzed.The experimental results show that the optimum conditions were as follows:molar ratio of pentaerythritol to phosphorus trichloride to bisphenol A was 1.0∶2.8∶2.0,the first and the second reaction held for about 3 h on the conditions of refluxing.The product,under this conditions,was...

Dibiphenol A pentaerythritol diphosphite was synthesized by using pentaerythritol,phosphorus trichloride and bisphenol A as raw material.The effects of reaction solvent,reaction time and molar ratio of the raw material on yields were analyzed.The experimental results show that the optimum conditions were as follows:molar ratio of pentaerythritol to phosphorus trichloride to bisphenol A was 1.0∶2.8∶2.0,the first and the second reaction held for about 3 h on the conditions of refluxing.The product,under this conditions,was a white flour solid and the melting point was 146 ℃—148 ℃,the yield of the product was about 93%.Elemental analysis,IR,and(()~1HNMR) were performed to characterize the structure of the product.

以季戊四醇、三氯化磷和双酚A作为原料合成了抗氧剂二亚磷酸二(双酚A)季戊四醇酯。探索了物料配比、反应溶剂的种类及用量和反应时间等反应条件对产率的影响,并通过正交试验法确定了适宜工艺条件。试验结果表明:反应溶剂为苯,用量为50 mL;物料配比〔m(季戊四醇):m(三氯化磷):m(双酚A)〕为1.0∶2.8∶2.0;第一步和第二步均回流反应3 h。在适宜工艺条件下所制得的产品为白色粉末状固体,熔点为146℃~148℃,产率约为93%。此外,通过元素分析、红外谱图和核磁共振对产品进行了物性和结构表征。
