31. As of 1994, not all the byproducts had been identified, but identified compounds include chloroform and carbon tetrachloride . 32. They later invented a carbon tetrachloride model called the " Petrolex " which was marketed toward automotive use. 33. The reduction of chlorinated chemical pollutants, such as vinyl chloride and carbon tetrachloride , also occurs through anaerobic respiration. 34. At elevated temperatures, it reacts with chlorine in the presence of graphite or carbon tetrachloride to give hafnium tetrachloride. 35. In the original triphasic protocol, the chalcone substrate is soluble in the organic phase, generally toluene or carbon tetrachloride . 36. Many of its applications previously used carbon tetrachloride ( which was banned in US consumer products in 1970 ). 37. For instance, carbon tetrachloride ( CCl4 ) etches silicon and aluminium, and trifluoromethane etches silicon dioxide and silicon nitride. 38. One specialty use of carbon tetrachloride was in stamp collecting, to reveal watermarks on postage stamps without damaging them. 39. These categories include toxicants such as polycyclic aromatic hydrocarbon ( PAHs ) and carbon tetrachloride ( CCl 4 ). 40. Unlike carbon tetrachloride , another energy.
