Rust inhibitor additive compositions, method of making, and aqueous fluids containing the same

摘要

The anti-rust properties exhibited by the aqueous fluids described herein are provided by one or more of the rust inhibitor additive composition prepared by reacting: (A) at least one aliphatic polycarboxylic acid acylating agent characterized by the presence within its structure of an aliphatic hydrocarbyl-substituent with (B) at least one hydroxy-substituted aliphatic amine, and (C) at least one basically reacting alkali metal compound.
