摘要
研究了合成阻燃剂四溴双酚A双 (2,3 -二溴丙基 )醚的新工艺 ,特点是通过加入表面活性剂TABS、催化剂SB和表面活性剂A的方法 ,提高产品纯度和降低游离酸的含量 ,成品的炭化温度为295℃ ,纯度大于95 %。
A newtechnology for synthesis of flame retardant tetrabromobisphenol A bis(2,3-dibromopropyl)ether is stydied,the technology features is by adding the surface active agent and catalyst.The method could boost purity of the product and decrease content of the free acid,the carbonized temperature of the product from the synˉthesis procedure is295℃and the purity of the product colud reach over95%.
