The invention provides an ammonium benzoate gas-phase slow-release rust preventive oil which is prepared from the following raw materials by weight: 150 parts of No. 120 solvent naphtha, 5 to 8 parts of rosin, 2 to 5 parts of zinc dust, 3 to 5 parts of sodium laureth sulfate, 15 to 18 parts of liquid paraffin, 3 to 5 parts of 3-aminopropyltrimethoxysilane, 10 to 15 parts of triethylenediamine, 10 to 13 parts of epoxidized soybean oil, 10 to 15 parts of xylene, 5 to 8 parts of a cross-linking agent TAIC, 1 to 3 parts of ferrocene, 4 to 6 parts of polyisobutylene, 1 to 2 parts of ammonium benzoate, 1 to 2 parts of benzotriazol, 1 to 2 parts of 2-aminoethyl-heptadecenyl-imidazoline, 1 to 2 parts of triethanolamine, 2 to 4 parts of zinc dialkyl dithiophosphate, 1 to 2 parts of sodium dodecyl benzene sulfonate, 6 to 8 parts of dimethicone, 10 to 12 parts of epoxidized triglyceride, 5 to 6 parts of a film forming resin and 1 to 2 parts of modified attapulgite. The gas-phase rust preventive oil has good antirust performance and an excellent contact antirust effect, so the rust preventive oil can be widely applicable to antirust action on inner cavities or other contact or non-contact metal positions of mechanical equipment.

A corrosion inhibitor composition includes between about 95 and about 99 percent by weight ammonium benzoate, and between 1 and about 5 percent by weight of silica. The composition may be water soluble for use in solution-based applications.

An environmental-friendly volatile corrosion inhibitor for carbon steel comprises sodium silicate with the mass-volume concentration of 0.8 g / L-1.2 g / L, alanine with the mass-volume concentration of 1.8 g / L-2.3 g / L, sodium benzoate with the mass-volume concentration of 6.8 g / L-8.3 g / L, and ammonium benzoate with the mass-volume concentration of 3.8 g / L-4.5 g / L, dissolved in distilled water. A preparation method of the environmental-friendly volatile corrosion inhibitor comprises the following steps: respectively weighing the sodium silicate, alanine, sodium benzoate and ammonium benzoate according to the mass-volume concentrations; respectively dissolving in distilled water with the volumes of 1 / 4 of those of the solutes, and uniformly stirring; after the four solutions are stilled, mixing and uniformly stirring. The environmental-friendly volatile corrosion inhibitor is formed by compounding the sodium silicate, alanine, sodium benzoate and ammonium benzoate, is environmental-friendly and efficient, has little pollution to the environment, has a good synergistic effect, and solves the problems that the conventional volatile corrosion inhibitor is poor in corrosion-inhibition performance and generates more pollution, adopts the simple preparation method, is convenient to use, and can prolong the service life of the carbon steel.

The invention relates to a method for preparing a hydrogen sulfide corrosion inhibitor used in an offshore oilfield produced oil pipeline and belongs to the technical field of petroleum additives. The method comprises the following steps: uniformly mixing an imidazoline compound, SPAN-80, rosin amine polyoxylethylene ether, sodium alga acid, methyl propanediol and ethanol, thereby obtaining a mixture I; uniformly mixing sodium chromate, sodium nitrite, sodium pyrrolidone carboxylate, hydroxyl ethyl benzoate, zinc borate, magnesium borate, dipentaerythritol, hydrogenated soya bean lecithin, triethylamine and propyl alcohol, thereby obtaining a mixture II; and uniformly mixing the mixture I, the mixture II, sodium benzoate, ammonium benzoate, sodium gluconate, sodium acrylate, thiosemicarbazide, carboxymethyl chito-oligosaccharide vanillic aldehyde Schiff base, thereby obtaining the hydrogen sulfide corrosion inhibitor. The corrosion inhibitor provided by the invention can effectively achieve a corrosion inhibition effect on the hydrogen sulfide in the pipeline under high salt conditions.

The invention provides a gaseous antirust material with a long-acting antirust effect. The gaseous antirust material comprises the following materials in parts by weight: 2.2-6.5 parts of ammonium benzoate, 15.5-25.5 parts of sodium nitrite, 72.5-81.5 parts of distilled water, 0.2-0.6 part of an emulgator, 5.5-8.5 parts of an enhancer and 3.5-5.5 parts of antirust microcapsules. The invention also provides a preparation method for the gaseous-phase antirust material with the long-acting antirust effect. The gaseous antirust material prepared in the manner of adding a gaseous slow-release material into the microcapsule according to the invention is capable of slowly releasing the stored gaseous slow-release material and has controllability. According to the invention, the enhancer is added in the process of preparing the gaseous antirust material, so that the adhesion of the antirust material on a thin oil film is greatly promoted, the antirust material is difficult to dry, crack, becomes crispy and falls off, the influence that the antirust effect become poor due to outdoor exposure and cold temperature can be reduced and the antirust effect is promoted.
