摘要：Inhibitive composition for prevention of corrosion and scaling of metallic surfaces in installations using water as the energizing or thermal fluid, comprises a dicarboxylic component (DC) and a fatty amine (AF). An inhibitive composition comprises: (a) a dicarboxylic compound (DC) of formula (I) and its mixtures; and (b) a fatty amine (AF) of formula (II). Z1OOC-(CH2)n-COOZ2 (I) R-(-NH-(CH2)m-)n'-NH2 (II) Z1, Z2 = H, Na, K, NH4+) or 1-4C alkyl; n = 5-12; R = 12-22C aliphatic hydrocarbyl, saturated or unsaturated; m = 2-8; n' = 0-7.
