Abstract
Process for the purification of 1 1 1-trichloro-2 2-bis (4-chlorophenyl) ethane comprising the material to be purified at a centrifugal force while progressively heating it to a temperature not exceeding the melting point of 1 1 1-trichloro-2 2-bis (4-chlorophenyl) ethane which causes the liquefied impurities to be released from the desired purified material by the applied centrifugal force.
