Abstract

1464161 Purification of pentachlorophenol DOW CHEMICAL CO 2 Oct 1974 42776/74 Heading C2C A process for the purification of pentachlorophenol comprises distilling the pentachlorophenol at subatmospheric pressure in the presence of a stabilizing amount of water and salicylaldehyde. The invention also relates to a fungicidal composition, which may also be used to preserve wood, comprising as the active ingredient a pentachlorophenol purified by the process according to the invention in association with a carrier therefor.
