Synthesis study of the antioxidant of tetrakis(2,4-di-tert-butyl phenyl)-4,4-biphenylenediphosphonite esters

摘要：

　　The antioxidant of tetrakis(2,4-di-tert-butylphenyl)-4,4-biphenylenediphosphonate (TBBPP) was synthesized using biphenyl,PCl3,AlCl3,and 2,4-di-tert-butylphenol as raw materials.Phosphite esters were selected as the novel decomplex agent to isolate the intermediate of 4,4-biphenylbisphosphorus dichloride complex from the complex it formed with AlCl3 during the reaction.The separate factors such as the mole ratio of the decomplex agent used,the decomplex temperature,and effect of decomplex agent were studied.The specifications of melting point,thermal stability and transmittance of the target compound synthesized were compared with the commercial product,and the results showed that the TBBPP synthesized in the study showed fairly better quality than the commercial one.
