TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The modified methanol comprises (in parts weight): methanol (70-96), hexadecyl modifier (3-10), flash point improver (1-7), additive (0.01-1), lubricant (0.001-1), anti-wear agent (0.001-1), antioxidant (0.001-1) and anti-corrosive agent (0.001-1). The hexadecyl modifier is prepared by mixing isooctyl nitrate, isoamyl nitrate, diethylene glycol nitrate and triethylene glycol dinitrate. The flash point improver is prepared by mixing water, glycol and pentaerythritol. The additive is prepared by mixing butyl acetate, vinyl acetate, cyclopentenyl ferrocene, dibutyl oxalate and methyl tertiary butyl ether. The lubricant is prepared by mixing alcohol lubricant, vegetable oil, trimethylolpropane ester, diesel engine lubricant CD30, CD40 and CD50. The anti-wear agent is prepared by mixing chlorinated paraffin, propylene glycol, triethanolamine, oleic acid, linoleic acid and ricinoleic acid. The antioxidant is prepared by mixing 2,6-di-tert-butyl-p-cresol, N,N-di-sec-butyl-p-phenylenediamine and Harout Krikorian (HN-K)101 antioxidant. The anticorrosive agent is prepared by mixing one or more of benzotriazole, N-methyl morpholine, corrosion inhibitor EC1023A and corrosion inhibitor NET114. The surfactant is prepared by mixing Tween 20 (RTM: Polysorbate 20), Tween 21 (RTM: Polysorbate 21), Tween 40 (RTM: Polysorbate 40), Tween 60 (RTM: Polysorbate 60), Tween 61 (RTM: Polysorbate 61), Tween 80 (RTM: Polysorbate 80), Tween 81 (RTM: Polysorbate 81), Tween 85 (RTM: Polysorbate 85), Span (RTM: Sorbitan fatty acid ester), Span 20 (RTM: Sorbitan fatty acid ester), Span 60 (RTM: Sorbitan fatty acid ester), Span 65 (RTM: Sorbitan fatty acid ester), Span 80 (RTM: Sorbitan fatty acid ester), Span 85 (RTM: Sorbitan fatty acid ester), Opadry 4 (RTM: Aqueous film coating system), Opadry 7 (RTM: Aqueous film coating system), Opadry 9 (RTM: Aqueous film coating system) and Opadry 10 (RTM: Aqueous film coating system). The surfactant has hydrophilic-lipophilic balance (HLB) of 3-6, preferably 3.6-5.6. The cosolvent is prepared by mixing propyl alcohol, isopropanol, butanol, isobutanol, octanol, n-amyl alcohol, isoamyl alcohol, n-caprylic alcohol, Ricinus oil, oleic acid, 260 solvent oil and refined coal tar.
