    摘要： Methods and cleaning compositions are provided for more effectively removing oil, grease, paint, varnish and other organic coatings from metallic surfaces in industrial equipment, oil well tubular goods and the like. The metallic surfaces are contacted with a cleaning composition comprised of an aqueous solution of an alkaline material, a nonionic surface active agent and a wetting agent for a period of time sufficient to remove the organic materials therefrom. The nonionic surface active agent is an alkylarylpolyether alcohol having an ethylene oxide content in the range of from about 10 to about 13 units of ethylene oxide per molecule, and the wetting agent is selected from the group consisting of aromatic phosphate esters of the formulae: ##STR1## and mixtures of such phosphate esters wherein x has a value in the range of from about 4 to about 6.

    摘要： Iron containing scale is removed from a metallic substrate by contacting the scale with a composition which is an aqueous solution consisting essentially of at least 0.5 weight percent of a polyphosphonic acid, or an alkali metal or amine salt of such acid, with the acid being selected from the group of acids having the formulae: ##STR1## where R.sub.1 is selected from the class consisting of C.sub.1 -C.sub.12 alkyl groups, and the group ##STR2## and ##STR3## where R.sub.2 is selected from the class consisting of --H, --PO.sub.3 H.sub.2, C.sub.1 -C.sub.12 alkyl groups, and the group ##STR4## The scale is removed from the metallic substrate by contacting THE DESCRIBED SCALE-BEARING SUBSTRATE WITH THE DESCRIBED COMPOSITION AT SELECTED TEMPERATURE AND PH conditions, and over a controlled time period and iron concentration in the composition so that the formation of an undesirable polymeric precipitate in the cleaning solution is avoided. Formation of the precipitate is also avoided by adding ammonium bifluoride to the composition.

    摘要： This application discloses a composition for and a method of using the composition to disperse hydrocarbon based components into a liquid carrier. The composition is comprised of a lower alkyl ester of a fixed oil, such as a modified vegetable oil, in combination with at least one other compound which enhances the ability of the ester to form an aqueous emulsion which can separate and which can alter the wetting character of the ester. The method comprises contacting a material comprised of hydrocarbon based components with an effective amount of composition for a time and a temperature sufficient to disperse the material into a liquid carrier.
