ABSTRACT:
The invention relates to an additive and to a method of corrosion inhibition on devices for the recovery and transportation of hydrocarbons in crude oil recovery and processing by adding an effective amount of an inhibitor. The inhibitor comprises an alkoxylated quaternary compounds of the formula 1where R1, R2are independently groups of the formula —(B)—(O—A)n—O—CO—R5or —(A—O)n—(C)—CO—O—R5, R3is C1— to C30-alkyl or C2— to C30-alkenyl, R4is an organic radical with 1 to 100 carbon atoms optionally containing heteroatoms, R5is an alkyl or an alkenyl, n is a number from 1 to 20, A is an alkylene group, B is an alkylene group, C is a C1— to C6-alkylene group and X is an anion, used as corrosion inhibitors.
