Abstract
Λ method of controlling corrosion in cooling water systems is disclosed which includes introducing into the cooling water system certain alkylalkanolamine compounds having the general formula: Rx-NHz-(CH2CH2OH)y wherein R is a C3 to C8 alkyl group either linear or branched, x and y are 1 or 2, z is 0 or I, x+y is not greater than 3, z = 3-x-y and the R groups are either the same or different C3 to C8 alkyl groups.
