A continuous method for destroying polyhalogenated biphenyls by reacting a solution of the biphenyls in an inert liquid at a concentration of from about 1% to about 5% by weight with a dispersion of sodium in a hydrocarbon oil.

Method for destruction of polyhalogenated biphenyls

A field method for removing polychlorinated biphenyls (PCB's) and similar halogenated aromatic hydrocarbons from silicone based oils and hydrocarbon fluids such as transformer oils contaminated with them by contacting the contaminated oil with a hydrocarbon dispersion of sodium, reacting the mixture of oil and sodium dispersion at a temperature above about 75.degree. C., and passing the treated oil through a filter medium or other separating means to remove particulate and other contaminating material.

Method of destruction of polychlorinated biphenyls

A process for the preparation of terephthalic acid which comprises electrolyzing disodium terephthalate in the anode compartment of an electrolytic cell whereby terephthalic acid product is precipitated and subsequently separated. In a preferred embodiment the disodium terephthalate is obtained by the aqueous hydrolysis of terephthalonitrile in the presence of a stoichiometric excess of sodium hydroxide.

Terephthalic acid process

A process for stabilizing lignitic and sub-bituminous coal against spontaneous combustion which comprises mixing as-mined lignitic or sub-bituminous coal with said hot, completely or partially dried lignitic or sub-bituminous coal in an amount to produce a weight ratio of dried coal to as-mined coal of from about 1:2 to about 10:1.
