(CN107974308) The invention discloses a coal-to-ethanol gasoline metal corrosion inhibitor, which is formed by mixing the following components by mass percentages: bis-imidazoline corrosion inhibitors 6%-15%, octadecylamine 1%-5%, cetylpyridinium chloride 5% to 12%, alkyl dimethyl benzyl ammonium chloride 2% to 9%, morpholine 1.5% to 3.5%, acetone oxime 0.5% to 2.5%, and the balance of cosolvent. The metal corrosion inhibitor of the present invention has the characteristics of easy availability of raw materials, moderate cost and convenience for use, and can effectively solve the corrosion problems existingin coal-to-ethanol gasoline and meet the corrosion resistance requirements (50 DEG C, 3 h, no more than first grade) of a coal-to-ethanol gasoline automotive oil system.
