    摘要： Disclosed herein are additives for petroleum hydrocarbons, e.g., gasoline, oil, and solvents, to inhibit corrosion or rusting of metals. The additives comprise a major amount of a liquid C.sub.21 -dicarboxylic acid having the following structure, the bis-alkanolamide derivative of this material, the mono-alkanolamide derivative of this material, or the salt of the monoalkanolamide derivative of this material: ##EQU1## wherein x and y are integers from 3 to 9, x and y together equal 12 and Z is a member of the group consisting of hydrogen and COOH, with one Z of each moiety. An additional aspect of the subject invention is that the C.sub.21 -dicarboxylic acid of the formula shown above may be blended with up to 80% by weight of such fatty acids as oleic acid, coconut fatty acid, soya fatty acid, tall oil fatty acids and others and still retain significant corrosion inhibiting properties. The alkanolamides are made by reacting the dicarboxylic acid or its sodium or potassium soap and monoethanolamine, diethanolamine or isopropanolamine.

    摘要： A METHOD OF DISPOSING OF CERTAIN PROCESS EFFLUENT WASTE STREAMS BY INJECTING THEM INTO SUBSTERRANEAN FORMATIONS WHICH ENTAILS INHIBITING THE FORMATION OF SOLID PRECIPITATES WHICH PLUG THE SUBTERRANEAN FORMATION. THE METHOD OF INHIBITING THE FORMATION OF PRECIPITATES INVOLVES LOWERING THE PH OF THE MIXED STREAMS AND OPTIONALLY REMOVING ANY ORGANIC PHASE CREATED THEREBY BEFORE INJECTION.
