Although the grouping of chemical substances according to atomic substances according to their atomic components and their structural arrangement must be arbitrary, particularly when a correlation of biologic effects must be considered also, certain of the halogenated compounds have similar characteristics. One group includes the di-, tri- and tetrachloro methanes, ethanes, ethylenes and propane. Another, the chlorobenzenes, has importance, as has epichlorhydrin. However, for these solvents, the group is made up principally of chlorinated aliphatic compounds and, of these, the principal economically important members are closely related. Essentially, the group is made up of chloroform, carbon tetrachloride, ethylene dichloride, tetrachloroethane, trichloroethylene, methylene chloride, dichloropropane, methyl chloride, isopropyl chloride, chlorobenzene, o-dichlorobenzene and trichloroethane.
