溴代叔丁烷的合成

Synthesis of 2-bromo-2-methylpropane

报道用叔丁醇和氢溴酸在浓硫酸作催化剂的条件下 ,合成溴代叔丁烷的实验研究 ,讨论了各种因素对其产率的影响。得到了其最佳合成条件 :叔丁醇∶氢溴酸∶浓硫酸为 8∶1 4∶7(体积比 )时 ,温度控制在3 0℃～ 3 5℃ ,其产率达到 67%。

bromo-2-methylpropane was synthesized using 2-methyl-2-propanol and hydrogen bromide in the presence of oil of vitriol.The effect of expermental condition on productionty were discussed,and the optimize comditions are as following:the volumn of 2-methyl-2-propanol ∶hydrogen bromide ∶oil of vitriol is 8 ∶14 ∶7 and the temperature ranges from 30℃～35℃,then the productivity can achieve 67%.
