Embodiment Construction

[0010] Reference figure 1 , Chlorination reactor (1), first ethyl chloride tower (2), HCI addition reactor (3), compressor (4), second ethyl chloride tower (5), crude ethyl chloride storage tank (6) According to its system function, it is constituted by assembling one piece by connecting pipeline (7).

[0011] When used, ethyl chloride is produced by liquid phase hydrochlorination of ethylene. Ethylene and hydrogen chloride are added to the device of the present invention at a pressure of 0.1~0.3MPa (or 0.1~0.9MPa) and room temperature (or -5~55℃), and then a chloroethane solution containing 2% aluminum trichloride is passed through to react to produce When the chloroethane overflows, flash evaporation, water washing, alkali washing, drying, and distillation obtain a chloroethane product with a purity of more than 99%.

Abstract

The invention discloses technology for producing chloroethane by an ethane hydrochlorination method. A device for producing chloroethane is formed by connecting a chlorination reactor, a first chloroethane tower, an HCl addition reactor, a compressor, a second chloroethane tower and a crude chloroethane storage tank through connecting pipelines according to the system functions thereof. The device has the advantages of reasonable design and convenient use. The technology is ideal chloromethane preparation process technology.

Description

Technical field [0001] The invention relates to a technology for chemically producing ethyl chloride, in particular to a technology for producing ethyl chloride by ethylene hydrochlorination, which is suitable for chemical synthesis of ethyl chloride. Background technique [0002] At present, ethyl chloride is an important raw material in the chemical industry and has a wide range of uses, but the production technology is complex, the cost is high, and the product quality is poor. Summary of the invention [0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a technology for producing ethyl chloride by ethylene hydrochlorination. The technology is not only reasonable in process, simple in preparation, but also easy to obtain raw materials, does not produce HCI by-products, does not discharge high-boiling chlorides, has high product yield and high raw material utilization rate. [0004] The technical scheme adopted by...
