    摘要: Amine derivatives which are compounds of the formula (I): ##STR1## in which R is a C.sub.6-20 hydrocarbon; Y is --CO--NH-- and n is an integer of 1 to 6; or ##STR2## in which X is an alkylene group of 2 to 6 carbon atoms and n is an integer of 0 to 6;each R.sub.1 is independently H, --(CH.sub.2).sub.1-4 COOH, a C.sub.6-20 hydrocarbon or C.sub.6-20 hydrocarbon-carbonyl;R.sub.2 is H, (CH.sub.2).sub.1-4 COOH or C.sub.6-20 hydrocarboncarbonyl;the compound containing at least one (CH.sub.2).sub.1-4 COOH group; or a salt thereof are useful in inhibiting corrosion of metals in oil- and gas-field applications, and also show low toxicity to marine organisms.
