Vinyl Chloride

Ⅰ. Overview

Vinyl chloride is also recognized as vinyl chloride and has the structural formula H2C=CHCl. Anesthetic, colorless, easy to turn into a liquid and at normal room temperature. It dissolves a bit in water and mixes well in alcohol and ether. The mixture with air is explosive and has a limit from 3.6% to 26.4% (volume).

Ⅱ. Production Method

The first common name is the calcium carbide method.

Vinyl chloride is made first by heating coke and calcium oxide and then mixing this with water to form acetylene from the previous step. Acetylene and hydrogen chloride react above the surface to give vinyl chloride. Since the catalyst is easily deactivated at high temperatures, the temperature during the reaction is generally controlled at 100-180℃.

2）Balanced oxychlorination method

During balanced oxychlorination, ethylene is divided in two directions: one is immediately chlorinated to make ethylene dichloride and the other is mixed with air and hydrogen chloride and then processed to form ethylene dichloride. After that, ethylene dichloride is broken down to form vinyl chloride. Hydrogen chloride made in the cracking process is sent back to the part where it is oxychlorinated. Ethylene is converted to ethylene chlorohydrin mainly by copper as catalyst and this is done at a temperature of 240℃. Ethylene production of ethylene dichloride and water can be seen when ethylene chlorination and oxychlorination are introduced by chlorine and oxygen.

Ⅲ. Usage

Most of the uses for vinyl chloride are connected to its importance as a raw material in the plastics industry, especially for producing PVC resin. More than any other material, PVC is the leading general-purpose plastic globally. Because of its low boiling point, vinyl chloride can serve as a refrigerant in refrigerators. In dye and fragrance extraction, using vinyl chloride helps to pull out and separate the valuable ingredients from the mix.

Other organic reactions are possible when vinyl chloride is used as a starting material.
