NOVELTY - Methanol fuel additive comprises (pts.wt.) modifier (15.9-20), oxidant (8-12), activator (12-8), anti-knock (15-17), detergent (0.54-2.48), catalyst (40.5-34.5), corrosion inhibitor (8-6) and anti-friction lubricant (0.06-0.02). The modifier is mixture of (pts.wt.) di-tert-butyl peroxide (3.3-6), pure benzene (3.3-6), propyl alcohol (6-2) and xylol (3.3-6); catalyst comprising (pts.wt.) solvent oil (22-18), acetone or acetylacetone (17-13) and diisopropylamine (1.5-3.5); and anti-friction lubricant comprising (pts.wt.) potassium permanganate (0.03-0.1) and potassium chloride (0.03-0.1).    USE - Methanol fuel additive.    ADVANTAGE - The methanol and gasoline can be soluble or instant in methanol gasoline configured by additive, and the appearance is bright and clear, no separation and no impurity; and methanol gasoline has no corrosion and swelling reaction to the present burning gasoline vehicle materials, and can be mixed or directly used with now-used unleaded gasoline in premise of non-change present burning gasoline vehicle engine and fuel supply system.    DETAILED DESCRIPTION - Methanol fuel additive comprises (pts.wt.) modifier (15.9-20), oxidant (8-12), activator (12-8), anti-knock (15-17), detergent (0.54-2.48), catalyst (40.5-34.5), corrosion inhibitor (8-6) and anti-friction lubricant (0.06-0.02). The modifier is mixture of (pts.wt.) di-tert-butyl peroxide (3.3-6), pure benzene (3.3-6), propyl alcohol (6-2) and xylol (3.3-6); oxidant comprising tert-butyl methyl ether (8-12 pts.wt.); activator comprising naphtha (12-8 pts.wt.); antiknock comprising (pts.wt.) hydroquinone (7-8) and isopropyl alcohol (8-9); detergent comprising (pts.wt.) propyl alcohol (0.12-1.74) and dicyclopentadiene (0.42-1.74); catalyst comprising (pts.wt.) solvent oil (22-18), acetone or acetylacetone (17-13) and diisopropylamine (1.5-3.5); corrosion inhibitor comprising methylbenzotriazole (8-6 pts.wt.); and anti-friction lubricant comprising (pts.wt.) potassium permanganate (0.03-0.1) and potassium chloride (0.03-0.1).
