41. Best yields are achieved with " N "-bromosuccinimide in carbon tetrachloride solvent. 42. This method involved heating silicon and oxygen by running silicon tetrachloride gas through an oxygen flame. 43. Unlike carbon tetrachloride , another energy. 44. I mean, those were the days when the maids scrubbed the floors with carbon tetrachloride ! 45. This was treated on the spot with carbon tetrachloride , and later with an ethylene oxide treatment. 46. Poisons, like carbon tetrachloride found in insecticides and lead can also cause headaches with repeated exposure. 47. "' Vanadium tetrachloride "'is the inorganic compound with the formula VCl 4. 48. Unlike the corresponding vanadium tetrachloride , the tetrafluoride is not volatile because it adopts a polymeric structure. 49. A laboratory route involves the reaction of benzene with carbon tetrachloride followed by hydrolysis of the resulting diphenyldichloromethane. 50. The hafnium tetrachloride remains substantially unchanged during the reduction and may be recovered readily from the zirconium subhalides.
