[0002] Chlorocyclohexane is a chemical with the molecular formula C6H11Cl. It is a colorless liquid with a suffocating odor. It is insoluble in water but soluble in ethanol. It is used as a pharmaceutical intermediate and is used to prepare the anti-epileptic and anticonvulsant drug benzhexol hydrochloride.

[0003] In the preparation method of chlorocyclohexane, the cyclohexane method uses cyclohexane and chlorine as raw materials, and the chlorine atom replaces a hydrogen atom on the cyclohexane ring to generate chlorocyclohexane and hydrochloric acid gas. The hydrochloric acid gas and a small amount of overflowed chlorine are discharged as tail gas, and the excess small amount of chlorine gas and the generated hydrochloric acid gas that have been introduced into the reaction tower need to be cleaned. Generally, clean water or a special cleaning liquid is used to flush and clean through a nozzle. However, it is not convenient to effectively clean the inner wall of the reaction tower.
