废氢溴酸用于制备溴十二烷的研究

Synthesis of bromododecane by waste hydrobromic acid

在有机溴化物的生产过程中 ,往往副产大量氢溴酸废液。由于这种废液成分复杂 ,大多数厂家没有很好的利用 ,为了使这些副产品的氢溴酸废液能够得到有效地利用 ,我们进行了一系列实验 ,找到了利用工业副产品氢溴酸废液生产溴十二烷的回收利用途径。以正十二醇和氢溴酸为原料 ,在浓硫酸的催化下 ,生产溴十二烷。对影响反应收率的各种因素进行了研究 ,确定了反应的最佳条件。

In organic bromide turn thing production line,it is usually by-product large quantity discard hydrobromic acid。Because the composition of this discard liquid is complicated,there is no good exploitation in majority factory out the way to synthesis bromohydrocarbon(bromododecane)with industry vice-producing hydrobromic acid。Ethyl lauryl alcohol respectively react with hydrobromic acid to product bromohydrocarbon,sulfuric acid for catalyst。The factors effecting on the ratio was investigated and the iptimum reaction conditions were obtained.
