[0061] The preparation method of above-mentioned anti-vanadium composition comprises the steps:
[0062] Step S110: preparing maleic anhydride grafted α-olefin.
[0063] In this embodiment, α-olefin, maleic anhydride and organic solvent are mixed and reacted at 140°C to 200°C for 2 hours to 6 hours to obtain a solution of maleic anhydride grafted α-olefin.
[0064] In one embodiment, the mass ratio of maleic anhydride to α-olefin is 1:1.2˜1:5.1.
[0065] In one embodiment, the grafting ratio of maleic anhydride to α-olefin is 90%-99%.
[0066] In one embodiment, the operation of step S110 is performed in a protective gas atmosphere. A protective gas atmosphere prevents the oxidation of α-olefins.
[0067] Preferably, the protective gas is nitrogen, argon or other inert gases.
[0068] In one embodiment, the α-olefin is at least one selected from α-olefins with a carbon chain length of 8-36.
[0069] Preferably, the α-olefin is at least one selected from α-olefins with a c...
Embodiment 1
[0108] The preparation process of the vanadium-inhibiting composition of the present embodiment is as follows:
[0109] (1) In an argon atmosphere, 23 parts of hexadecene-1, 10 parts of maleic anhydride and 380 parts of mixed trimethylbenzene (manufacturer: Ningbo Guangchangda New Material Co., Ltd.) were mixed and heated at 140°C After reacting for 4 hours, a solution of maleic anhydride grafted α-olefin was obtained.
[0110] (2) Add 5 parts of polymethacrylic acid, 75 parts of light magnesium oxide and 10 parts of ethanol to the obtained solution of maleic anhydride grafted α-olefin, stir and microwave under 915MHz, 60°C After reacting for 60 minutes, a dilute solution of the vanadium inhibitor was obtained, which was an off-white translucent liquid.
[0111] (3) Add 4 parts of p-toluenesulfonyl isocyanate to the dilute solution of the obtained vanadium inhibitor and mix and distill under reduced pressure at 100° C. to 180° C. and 100 Pa for 1.5 hours to obtain the vanadiu...
Embodiment 2
[0113] The preparation process of the vanadium-inhibiting composition of the present embodiment is as follows:
[0114] (1) In a nitrogen atmosphere, 34 parts of tetradecene-1, 10 parts of maleic anhydride and 540 parts of mineral oil (manufacturer: Total) were mixed and reacted at 200° C. for 3 hours to obtain horse A solution of anhydride-grafted α-olefins.
[0115] (2) Add 8 parts of α-terpene resin, 80 parts of active magnesium oxide and 35 parts of ethylene glycol to the obtained maleic anhydride grafted α-olefin solution and mix them under microwave conditions of 915MHz and 70°C The reaction was carried out for 40 minutes to obtain a dilute solution of the vanadium inhibitor, which was a light gray translucent liquid.
[0116] (3) Add 5 parts of orthoformic acid triester to the obtained dilute solution of the vanadium inhibitor, mix and distill under reduced pressure at 80°C to 150°C and 100Pa for 1 hour to obtain the vanadium inhibitor composition, which is a gray Tra...
