Vinyl Chloride Monomer (VCM) Production and …
2007/11/7· There are two routes commonly used to make EDC: direct chlorination using pure chlorine and ethylene, and oxychlorination in which the ethylene reacts with chlorine in hydrogen chloride. The EDC is then converted to VCM by thermal cracking and the hydrogen chloride by-product can be recycled to an oxychlorination plant to make more EDC.

Revis et al. (1986) exposed white rabbits for 3 months to chlorine in drinking water at a concentration of 15 mg/L (pH 6.5 or 8.5) administered in conjunction with a diet of 300 µg iodide/kg (sufficient) and 950 µg iodide/kg (high) in a reduced-calcium diet (previous
In one of the industrial processes used for manufacture …
In the manufacture of sodium hydroxide, hydrogen gas and chlorine gas (X) are formed as by-products. When chlorine gas (X) reacts with lime water, it forms calcium oxychloride (bleaching powder) Y. The reactions are 2NaCI(aq) + 2H 2 O(l) → 2NaOH(aq) + Cl 2
Chlorination and the Law of Unintended Consequences
However, chlorine also reacts with any organic matter present in the water. Among the products formed are chloroform and a variety of other trihalomethanes ( THM s). Although these substances are normally present only in the range of parts per billion (ppb), they nevertheless have caused considerable anxiety because several of them are known or suspected carcinogens .
