Abstract:
The invention relates to antifreeze concentrates which are based on alkylene glycols or derivatives thereof or on glycerin, containing 0.05 to 10 wt. % of one or more cathoxylic acid amides and/or sulfonic acid amides in relation to the total quantity of concentrate.
Abstract:
A metal article is protected from corrosion under prolonged exposure to normal ambient atmospheric conditions which cause such corrosion by coating the metal article, optionally in the presence of an adherent organic resinous coating, which comprises treating the metal with an effective amount of effective amount of one or more hydrocarbyl-substituted sulfonyl amido diphenylamine compounds for the corrosion protection of the metal article. These compound(s) are of the formula p-(R--SO.sub.2 --NH--C.sub.6 H.sub.4 --NH)--C.sub.6 H.sub.5, where R is a substituted or unsubstituted hydrocarbyl group selected from the group consisting of alkyl, aryl, alkaryl, aralkyl, alkenyl, and cycloalkyl. A particularly preferred compound is p-(p-toluene sulfonyl amido)-diphenylamine.

Abstract:
Methods of employing corrosion inhibitors with oxidizing and/or non-oxidizing biocides, such as peroxycarboxylic acids, to provide corrosion protected compositions are disclosed. Various corrosion inhibitors further provide biocidal efficacy in addition to the corrosion protection providing further benefits for application of use. Methods of employing corrosion protected biocide compositions, such as peroxycarboxylic acid compositions, for corrosion protection are particularly well suited for treating fluids intended to flow through pipes, namely in the energy industry, water and paper industries, etc. Methods providing suitable corrosion protection in comparison to untreated systems and corrosion protected systems using conventional corrosion inhibitors, such as quaternary amines and imidazolines commonly used in the industry, are disclosed.
