磷系阻燃剂双酚A对二苯磷酸酯（BDP）的工业合成 摘要 本文对磷系阻燃剂双酚A对二苯磷酸酯（BDP）进行在工厂合成介绍。以三氯氧磷、 双酚 A和苯酚为原料, 在催化剂作用下合成四氯双酚 A磷酸酯单体 (中间体) , 再与苯酚缩聚合成双酚 A四苯基双磷酸酯。目前所合成的阻燃剂应该是 BDP 和二聚物为主要成分的混合物。本文简单的介绍了BDP目前的几种生产方法以及市场状况，该中间体的市场巨大，该工艺具有良好的经济效益。本文详细介绍了工厂中生产该产品的操作过程，提及到整个生产工艺流程，以及DCS详细操作的参数信息。通过制品分析，讲述了生产过程中的IPC控制、温度控制、搅拌控制等对生产的影响。工艺改进方面对比了原生产工艺进行了部分设备改进，以及完成了从一次性入料至分段入料的重大改进,减少工程时间（回收氧磷保持时间缩短165min）；大大降低了DIP管的堵塞频率，减少因更换DIP管而造成的工程延误。目前仍采用低TPPO品的摩尔比配方（3.3：1）是对企业产品稳定性的措施。化工生产具备一定的不确定性和危险性，所以生产工艺和设备还需要持续优化和改进。该产品的生产有有毒物质的参与，本文还介绍了工厂生产的安全防范知识，在工厂中操作要提高个人安全素质，避免危险的发生，不能避免的要做好个人防护。 关键字：BDP 工艺流程 DCS 工艺改进 分段入料 The industrial synthesis of phosphorus-based flame retardant bisphenol A diphenyl phosphate (BDP) Abstract In this paper, a phosphorus flame retardant bisphenol A diphenyl phosphate ( BDP ) introduced in the factory synthetic .Phosphorus oxychloride , bisphenol A and phenol as raw materials,Tetrachloro- bisphenol- A in the catalyst synthesis of phosphoric acid ester monomer (Intermediate ),With phenol , polycondensation synthesis bisphenol A 4 - phenyl- bisphosphate .Currently , the synthesis of flame retardants should be BDP and dimer as a main component of the mixture .This paper describes the factory production of the product during the operation , referring to the entire production process , as well as the detailed operation of DCS parameter information.Tells the story of the IPC in the production process control, temperature control , stirring control the impact on production .Process improvement compared the original production process were part of the equipment improved , and the completion of a significant improvement from the one-time feed to the sub- feed ,Reduce engineering time ( recovery of phosphorus oxychloride keep time 165min ) ; greatly reduces the frequency of DIP tube blockage , reducing slippage caused by the replacement of DIP tube.The product involved in the production of toxic substances , the article also describes the plant security knowledge to effectively do a good job
