This invention provides a series of novel acrylated, substituted imidazoline corrosion inhibitors of the formula:wherein Ris an alkyl radical having from 2 to 8 carbon atoms; Ris a radical derived from a fatty acid; and Ris a radical derived from an unsaturated acid and a method for inhibiting corrosion in metallic flow lines through the introduction of such inhibitors into a system wherein corrosion is sought to be precluded.

Imidazoline corrosion inhibitors

An alkoxylated alkylphenol-formaldehyde-diamine polymer prepared by alkoxylating an alkylphenol-formaldehyde-diamine polymer and use of the alkoxylated alkylphenol-formaldehyde-diamine polymer to resolve water-in-oil emulsions, especially emulsions of water in crude oil.

Alkoxylated alkylphenol-formaldehyde-diamine polymer

The present invention relates to a process for making and a method for using a corrosion inhibitor composition to reduce the corrosion rate of a metal by a fluid containing a corrosion agent. The corrosion inhibitor composition comprises at least a quaternized compound. Examples of the quaternized compound are quaternized imino imidazolines and quaternized amido imidazolines.

Corrosion inhibitor compositions

The present invention relates to a process for making and a method for using a corrosion inhibitor composition to reduce the corrosion rate of a metal by a fluid containing a corrosion agent. The corrosion inhibitor composition comprises at least a quaternized compound having an amido moiety. An example of the quaternized compound is a quaternized amido imidazoline.

Rust of ferrous metal surfaces that are in contact with gasohol or alcohol fuels is inhibited by the addition of a corrosion inhibiting amount of the combination of (A) a substituted imidazoline and (B) an alkenyl succinimide of a mixture of alkylenepolyamines.

Corrosion inhibitor for alcohol and gasohol fuels

Detergents for hydrocarbon fuels, and hydrocarbon fuels containing detergents are provided wherein the detergent is comprised of an alkenylsuccinimide prepared by reacting an alkenylsuccinic acid or anhydride with a mixture of amines. The alkenyl substituent is substantially derived from an olefin having a carbon chain of from 8 to 10 carbons or mixtures thereof.

Hydrocarbon fuel detergent

A corrosion inhibitor composition for hydrocarbon fuels comprising a C.sub.10 -C.sub.24 alkenyl succinic anhydride esterified with between 0.5-1.5 moles of a water-soluble glycol and then neutralized with an amine. The invention also contemplates improved hydrocarbon fuels which comprise a major portion of such fuels which contain small quantities of the above described composition.
