    • 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 1 where R1, R2 are independently groups of the formula —(B)—(O—A)n—O—CO—R5 or —(A—O)n—(C)—CO—O—R5, R3 is C1— to C30-alkyl or C2— to C30-alkenyl, R4 is an organic radical with 1 to 100 carbon atoms optionally containing heteroatoms, R5 is 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.
    • 本发明涉及通过添加有效量的抑制剂来回收和运输原油回收和加工中的烃的装置的腐蚀抑制的添加剂和方法。 抑制剂包括式1的烷氧基化季铵化合物,其中R 1,R 2独立地是下式的基团 - (B) - (OA)n 或 - (AO)n - (C)-CO-OR 5,R 0 > 3是C 1至C 30 - 烷基或C 2 - 至C 30 - - 烯基,R 4是具有任选含有杂原子的具有1至100个碳原子的有机基团,R 5是烷基或烯基,n是1至20的数 A是亚烷基,B是亚烷基,C是C 1 -C 6亚烷基,X是用作腐蚀抑制剂的阴离子。
