Study on the Preparation of Micro-Emulsified Diesel Oil and its Influencing Factors

Abstract:

In this experiment, the micro-emulsified diesel oil is prepared by using alkanol amide from the reaction between oleic acid and ethanolamine and the mixture of them and with its by-products as the surfactant and alcohols with different carbon chain lengths and molecular structures as the co-surfactant. The experiment explores the effect of the proportion and dosage of the surfactant on the water solubilization, studies the influence of the category, construction and dosage of the co-surfactant on the water solubilization and its stability, and also discusses the impact of concentration of the electrolyte on the micro-emulsion. The experimental result shows that the no1-ionic surfactant can be used to prepare the W/O micro-emulsified diesel oil when this is satisfied: m (oleic acid): m (ethanol amine) =10:1 and that 1-pentanol, isoamyl alcohol, 1-hexanol, benzyl alcohol can all be used as its co-surfactant. The co-surfactant of benzyl alcohol or 1-pentanol helps to ensure its mechanical and temperature stability, and to prepare the micro-emulsified diesel oil with no1-ionic surfactant from the reaction between oleic acid and ethanolamine as surfactant, one of the best formulation should be like this: room temperature(20°C），ω（0 # diesel oil）=70.6%, ω（surfactant）=9.2%, ω（benzyl alcohol）=5.0%, ω（inorganic salt solution）=15.2%.
