Abstract

The invention discloses a device and a process for producing high-purity parachlorophenol. The device comprises a reaction kettle, a storage tank, a distillation tower, a collecting tank, a condensation tank, a pressure reducing tower, a separator and a product tank. The device and the process have the advantages that the high-purity parachlorophenol can be produced by the aid of the device and is high in yield; reaction causes little pollution; a gas flow meter is arranged on a chlorine flowing pipeline of the device, accordingly, the inlet quantity of gas can be effectively controlled, and deep reaction can be prevented; a temperature measuring opening is formed in the top of a reactor and can bring convenience for measuring the temperatures, and accordingly side reaction due to excessively high temperatures and influence on the purity and the quality of products can be prevented.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a production device of high-purity p-chlorophenol and a production process thereof. Background technique [0002] p-Chlorophenol is used to make dyes and medicines, and also used as a denaturant for alcohol and a selective solvent for refined mineral oil. It can also be used in microscopic analysis, pharmaceutical industry, plant growth promoter, and can be used in various fields such as medicine, pesticides, dyes and other organic synthesis raw materials, and has a wide range of applications. In the prior art, many impurities are involved in the production of p-chlorophenol, and high-purity p-chlorophenol cannot be extracted, and a lot of waste gas is discharged during the process of extracting p-chlorophenol, causing environmental pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-purity p-...
