Abstract
The present invention generally relates to methods and compounds for preventing metal corrosion. More specifically, the method comprises contacting a hydrocarbon-containing liquid with a composition in an effective amount to prevent metal corrosion.
Claims19
A method for preventing metal corrosion, the method comprising contacting an effective amount of an anticorrosion composition with a hydrocarbon-containing liquid, the hydrocarbon-containing liquid being in contact with a metal, the anticorrosion composition comprising a solvent and a compound of Formulae I or II:
- wherein
- R1 and R2 are independently substituted alkyl or unsubstituted alkyl;
- R3 is hydrogen, substituted alkyl, or unsubstituted alkyl;
- R4 is substituted alkyl, unsubstituted alkyl, substituted aryl, or unsubstituted aryl;
- R5 is hydrogen, substituted alkyl, or unsubstituted alkyl;
- and
- R6 is hydrogen, substituted alkyl, unsubstituted alkyl, or —S-heterocyclo.
The method of 1, wherein R3 and R5 are independently hydrogen or unsubstituted C1 to C6 alkyl.
A method for preventing metal corrosion, the method comprising contacting an effective amount of an anticorrosion composition with a hydrocarbon-containing liquid, the hydrocarbon-containing liquid being in contact with a metal, the anticorrosion composition comprising a solvent and a compound of Formula IIA:
- wherein R7 and R8 are independently hydrogen or alkyl.
