Embodiment 1

[0056] Add 0.11g of tetradecyltrimethylammonium bromide, 0.9g of amyl alcohol, 6.5g of oleic acid, 0.86g of ammonia water, and 0.19g of monoethanolamine into the reaction kettle, mix and stir evenly to obtain a microemulsion diesel oil additive.

[0057] Add the above-mentioned microemulsion diesel oil additive into 78g diesel oil, mechanically stir evenly, then add 13.5g water, stir evenly to obtain a transparent and clear solution, which is microemulsion diesel oil.

Embodiment 2

[0059] Add 0.18g of cetyltrimethylammonium bromide, 8.5g of oleic acid, and 0.86g of monoethanolamine into the reaction kettle, mix and stir evenly to obtain a microemulsion diesel oil additive.

[0060] Add the above-mentioned microemulsion diesel oil additive into 76 g of diesel oil, mechanically stir it evenly, then add 14 g of water, and stir evenly to obtain a transparent and clear solution, which is the microemulsion diesel oil.

Embodiment 3

[0062] Add 1.0 g of amyl alcohol, 7.5 g of oleic acid, and 1.2 g of ammonia water into the reaction kettle, mix and stir evenly to obtain a microemulsion diesel oil additive. Add the above-mentioned microemulsion diesel oil additive into 76.5g diesel oil, stir evenly, then add 13.9g water, stir evenly to obtain a transparent and clear solution, which is microemulsion diesel oil.

Abstract

The invention discloses a micro-emulsified diesel oil additive, comprising the following components mixed together according to weight proportion: 1-3 of cationic surfactant, 7-30 of middle chain alcohol; 60-90 of organic acid, 3-15 of ammonia and/or ethanolamine and 0-6 of ethanol. The invention has the advantages of transparency, long-preserving time, simple production technique and low cost; at the same time, by adopting the anionic-cationic surfactant mixed system, the invention has large water solubilization and is stable.

Description

technical field [0001] The invention relates to a diesel oil additive and its application, in particular to a microemulsion diesel oil additive and its application in diesel oil microemulsion. technical background [0002] With the rapid development of society, the non-renewable petroleum resources are constantly decreasing. Therefore, the conservation and full utilization of petroleum resources has become an urgent research topic. The technology of adding water or alcohol to oil has been proposed since the beginning of last century, but after the 1970s, with the development of surfactant research, the research on this topic has only been deepened. At present, most of the reports are adding microemulsifiers to diesel oil to microemulsify diesel oil, so as to improve diesel combustion efficiency and reduce exhaust pollution. Alcohols and surfactants are generally added to diesel oil; the types of alcohols are generally medium-carbon chain alcohols, and there are many types o...
