The invention is a morphine derivative gas-phase corrosion inhibitor preparing method, including the steps: mixing morphine with secondary amine, dropping in formaldehyde or aldehyde solution, making them uniformly mix and react, making acid curing reaction on the mixed solution and fatty acid/benzene carbonic acid, stirring, filtering and obtaining the object product. The raw materials such as morphine, secondary amine, formaldehyde/aldehyde, fatty acid and benzene carbonic acid are all easy to obtain and cheap, and suitable for large-scale industrialized production. The preparing course has only three steps and is relative simple, all the reactions can be completed on routine conditions, and the requirements for devices are low, thus further reducing the preparation cost. In addition, all the anticorrosive experiments show that the object product has excellent corrosion inhibiting property.

The invention relates to an amino acid gas-phase corrosion inhibitor and a preparation method and application thereof.The gas-phase corrosion inhibitor comprises amino acid and montmorillonite, the gas-phase corrosion inhibitor comprises, by mass, 60-70% of amino acid and 30-40% of modified montmorillonite, the amino acid is alanine, and the modified montmorillonite is alanine. The modified montmorillonoid is organic montmorillonoid or carbon dot montmorillonoid; the method specifically comprises the following steps: preparing alanine into an alanine aqueous solution, mixing the alanine aqueous solution with organic montmorillonite or carbon dot montmorillonite, heating, stirring, carrying out suction filtration, and drying to obtain the gas phase corrosion inhibitor. Compared with the prior art, the characteristics of abundant pores, large specific surface area, fine granularity and the like of the montmorillonite are utilized, and the montmorillonite is compounded with the green amino ...
