| titleOfInvention | Green synthesis method of chlorocyclohexane |
| abstract | The invention discloses a green synthesis method of chlorocyclohexane, which comprises the following steps: cyclohexane and chlorine are used as raw materials, and cyclohexane, chlorocyclohexane and polychlorinated cyclohexane are separated from chlorination products through distillation; absorbing hydrogen chloride by a falling film absorption method, and recovering the hydrogen chloride as industrial hydrochloric acid; hydrolyzing the byproduct polychlorinated cyclohexane by using alkali liquor to generate a cyclohexene substance, separating the hydrolysate to obtain 2-cyclohexenol, and carrying out catalytic hydrogenation reaction on the residual cyclohexene substance to obtain cyclohexane. The invention has fast reaction rate, adopts light as initiator and has no problem of catalyst recovery. The method has the advantages that the difficultly-treated polychlorinated cyclohexane is converted into the important chemical raw materials 2-cyclohexene alcohol and cyclohexane, so that the production cost is reduced, the cyclic utilization of resources is realized, the requirements of green environmental protection and sustainable development are met, the carcinogen dioxin generated by the incineration of the polychlorinated cyclohexane is avoided, the chemical production is cleaned, and the method has important practical significance. |
