As calciners they are used in tin mines and for the chlorination of silver ores.
Long-continued treatment with halogens may, in some cases, result in the formation of aromatic compounds; thus perchlorbenzene, C 6 C1 6, frequently appears as a product of exhaustive chlorination, while hexyl iodide, C 6 H 13 I, yields perchlorand perbrom-benzene quite readily.
Effective avoidance of chlorination byproducts could therefore require major changes in behavior.
Simple chlorination units using sodium hypochlorite (bleach) help to ensure potability to point of use.
Chlorination of this substance gave a monochloracetic acid; we will assume the chlorine atom to replace the b hydrogen atom.
