Use of complex polyester amines and polyester quaternary ammonium compounds as corrosion inhibitors for metal surfaces, and a method for protecting a metal surface from corrosion by contacting the metal surface with said corrosion inhibitor.

A hydrocarbon tank system environment corrosion inhibitor includes use of inert gas, preferably Nitrogen, to blanket ullage and interstice through the tank system. Blanket gas is provided is controller into coupling to access ullages. Blanket gas is provided upon fueling events to stabilize the pressure m the system and prevent entry of atmospheric air and water (vapor). Blanket gas may be continuously run into the ullage and/or other spaces in tank system. A controlled system allows for monitoring of pressures in the tank, and thereby identifies pressure events and even leaks in system due to unusual events, or general loss of pressure.

An embodiment provides a method for measuring amines in a solution, including: preparing an indicator-metal complex, wherein the indicator-metal complex comprises an indicator and a metal; introducing the indicator-metal complex to a solution, wherein the solution contains an amount of amine, wherein the amine activates the indicator-metal complex causing a change in fluorescence intensity of the indicator-metal complex; and measuring the amount of amine in the solution by measuring the change in fluorescence intensity of the indicator-metal complex. Other aspects are described and claimed.

A surface protection composition which is hard to deform or flow even placed under environments of a large temperature change with an external physical load such as pressure, and which stably protects a metal surface. A terminal fitted electric wire coated with the composition. The surface protection composition contains a high-consistency material (A) containing a lubricant base oil and an amide compound, and a phosphorus composition (B). The phosphorus composition (B) contains a composition (b1) containing one or more compounds represented by the general formulae (1) and (2) and one or more metals and/or one or more amines. The phosphorus composition (B) also contains one or more compounds (b2) represented by the general formula (3).
