ANALOGOUS
COMPOUNDS OF PCB's - POLYCHLORINATED TERPHENYLS (PCT's)
The analogous
compounds of PCB's are alkylated chlorobiphenyls and polychlorinated terphenyls
and higher phenyls. The properties of these compounds are very close to PCB's
and depend on degree of chlorination. The
Polychlorinated Terphenyls (PCT's) can be represented as C18H14-nCln in which
`n' is the number of chlorine atoms, which can range from 1 to 14. The physical
and chemical properties of PCT's are similar to whose of PCB's and depend on the
degree of chlorination. Similar to the PCB's the Polychlorinated terphenyls are
not marketed as composition specification, but based on their physical properties,
which depend on degree of chlorination. The trade names of PCT's are generally
similar to those given for PCB's. However, in the Aroclor series, terphenyls are
indicated by 54 at the first two places of the four-digit code. The PCT's are
commercially known as Kaneclor in Japan.
