研究了四溴双酚A的合成条件,并利用TG-DTA热分析技术研究了其阻燃过程的木炭产量和热动力学参数.结果表明,合成条件由室温改为冰水浴时,四溴双酚A产率由70.7%提高到85.6%,溴含量由54.1%提高到55.4%;溶剂由无水乙醇改为苯时,产率由85.6%提高到93.4%,原料配比由1 ∶ 2改为1 ∶ 2.4时,产率由93.4%提高到94.2%,溴含量由56.1%提高到58.8%,熔程为179.0～181.3 ℃.杉木经四溴双酚A处理后,产炭率由31.2%提高到45.4%.淋洗实验表明,磷酸氢二铵处理杉木的产炭损失率达26.7%,而四溴双酚A处理的产炭损失率只有4.27%.因此,合成四溴双酚A的最佳条件是在冰水浴中,以苯作溶剂,双酚A与溴的原料配比为1 ∶ 2.2～2.4...

The synthetic conditions of tetrabromobisphenol A were studied. Char yield and thermokinetic parameters during pyrolysis of wood treated with tetrabromobisphenol A were studied by TG-DTA method. Results showed that tetrabromobisphenol A yield increased from 70.7% to 85.6%, and bromine content increased from 54.1% to 55.4% as the condition was converted from room temperature to ice-water bath. The yield increased from 85.6% to 93.4% as benzene was used as a solvent to replace alcohol. The yield increased from 93.4% to 94.2%, bromine content increased from 56.1% to 58.8% and melting point reache...
