A review of the available information shows that C2C16 production by thermal decomposition of CC14 is the simplest. Results are presented to show that thermal decomposition at 750°, gives, under suitable conditions, quantitative formation of C2C16 from CC14 decomposed. The decomposition of CC14 is, however, about 50%; but the undecomposed CC14 itself can be easily obtained from natural gas. With abundance of natural gas in both wings of Pakistan, it would be feasible for some of it to be chlorinated to CC14. Besides being a starting material for C2C16, CC14 itself has great importance as a commercial solvent which has particular advantage in being free from fire hazards.
