ABSTRACT:
Liquid dehalogenating agents containing (a) 30 to 70% by weight of an alkali metal alcoholate having 6 to 20 carbon atoms; (b) up to 12% by weight of an alcohol having 6 to 20 carbon atoms; (c) 5 to 40% by weight of a polyether; and (d) 10 to 65% by weight of a halogenfree hydrocarbon oil are efficient for the dehalogenation of waste oil while at the same time exhibiting improved resistance to hydrolysis and oxidation. In addition the present dehalogenating agents are homogeneous, stable for storage at room temperature, pumpable, and readily measurable, and they may be used in unheated pipes and pumps without causing deposits or plugging.
