USE OF A SECONDARY AMINE AS A CORROSION INHIBITING AND ANTIMICROBIAL AGENT AND AN AQUEOUS ALKALINE INDUSTRIAL FLUID CONTAINING SAID AMINE

摘要

Secondary amines having the formula (I): R(Y)sNHX, in which R is an hydrocarbon group having 2-12 carbon atoms, Y is the group -CH(OH)CH2-, -OCH2CH(OH)CH2-, or -O(CH2)3-, X is an alkyl group having 2-3 carbon atoms and substituted with hydroxyl groups in the 2-position or in the 2- and 3-positions, and s is 0 or 1 with the condition that when s is 0, then X is an alkyl group substituted in the 2- and 3-positions, or a salt thereof, are used as anticorrosion and antimicrobial agents. They are suitable to be incorporated in aqueous, alkaline, industrial fluids. An aqueous, alkaline metal working fluid is also disclosed.
