Abstract |
Industrial use of chlorine is growing at a rapid rate. About 3.0 percent of the total is used for water sanitation and 16.0 percent is consumed in the pulp and paper industry. The balance of 81.0 percent is used in the production of chlorinated hydrocarbon products. Because of the apparent potential for atmospheric pollution with chlorine, hydrochloric acid and various hydrocarbon compounds, a survey of the processes employed for the production of the sixteen most important chlorinated hydrocarbon products was undertaken. Past, present and projected production figures for these materials are shown and an analysis of processes is reported. The sixteen major products studied include: Carbon tetrachloride; Chloroform, Epichlorohydrin; Ethyl chloride; 1, 2 - dichloroethane; Allyl chloride; Hydrogen chloride; Methyl chloride; Methylene chloride; Monochlorobenzene; Phosgene; Propylene oxide; Tetrachloroethylene; 1, 1, 1 - trichloroethane; 1, 1, 2 - trichloroethylene; and Vinyl chloride. |
