ABSTRACT:
The decomposition of chlorinated phenols, especially pentachlorophenol, during exposure to high temperatures (e.g., storage and distillation) is markedly reduced by incorporating into the molten chlorinated phenol at least about 0.25 percent by weight of said impure chlorinated phenol of at least one monohydric primary alcohol having at least 14 carbon atoms, one hydroxyl group, and devoid of any other heteroatoms or ether linkages; selected from the group consisting of straight-chain or branched monohydric primary alcohols or a mixture of said straight-chain or branched monohydric primary alcohols.
