Examples
Embodiment 1
[0028] In terms of mass percentage, prepare 40% heptadecyl hydroxyethyl imidazoline, 5% dimerized oleic acid, 5% polyaspartic acid, 10% benzotriazole, 3% hexadecane amine, 3% N-methylpyrrole, 0.1% N,N'-disalicylidenediamine, and the balance is isopropanol.
[0029] First add the dispersant to the blending kettle, then add imidazoline derivatives, dimer acid, polyaspartic acid, benzoxazole, organic amine, nitrogen-containing heterocyclic compounds, metal ion deactivator while stirring, fully Stir evenly to form a transparent liquid to obtain the multi-metal corrosion inhibitor for vehicle methanol fuel of the present invention.
Embodiment 2
[0031] In terms of mass percentage, prepare 30% heptadecenylamine ethyl imidazoline, 10% dimerized linoleic acid, 7% polyaspartic acid, 3% benzotriazole, 5% decane Octamine, 6% of 2,5-dimethylpyrrole and 0.05% of N,N'-disalicylidenediamine, and the balance is isobutanol.
[0032] First add isobutanol into the blending kettle, then add heptadecenylamine ethyl imidazoline, dimer linoleic acid, polyaspartic acid, benzotriazole, octadecylamine, pyrrolidone and N , N'-disalicylidene propylenediamine, fully stirred until the mixed solution becomes transparent, and the multi-metal corrosion inhibitor for vehicle methanol fuel of the present invention is obtained.
Embodiment 3
[0034] In terms of mass percentage, prepare 35% oleic imidazoline, 8% dimerized oleic acid, 7% polyaspartic acid, 5% benzotriazole, 3% hexadecylamine, 2% 2,5-dimethyl-1-phenylpyrrole, 0.08% N,N'-disalicylidenediamine, and the balance is isoamyl alcohol.
[0035] First add isoamyl alcohol into the mixing tank, then add oleic imidazoline, dimer oleic acid, polyaspartic acid, benzotriazole, hexadecylamine, 2,5-dimethyl- 1-phenylpyrrole and N,N'-disalicylidene propylenediamine are fully stirred until the mixed solution becomes transparent, and the multi-metal corrosion inhibitor for vehicle methanol fuel of the present invention is obtained.
