Methanol gasoline water soluble agent

Abstract

The invention relates to a methanol gasoline water soluble agent, belonging to the field of alcohol gasoline alternative fuel additives, and being prepared from the following raw materials by weight percent: 54.7 percent to 62.5 percent of partially saponified ammonium soap and 37.5 percent to 45.3 percent of fatty alcohol, wherein the partially saponified ammonium soap is an incomplete saponified product fatty acid ammonium generated by partial saponification reaction of animal and vegetable oils, waste oil or organic acid and organic ammonium or inorganic ammonium. Compared with a traditional cosolvent, the methanol gasoline water soluble agent has the advantages of simple preparation, little agent addition, low cost, favorable effect and the like. By using the water soluble agent in methanol gasoline of each grade of M15 to M100, the methanol gasoline can generally keep non-stratification by being dissolved in water for 3 percent to 5 percent. Finished methanol gasoline can be dissolved in water for 6 percent to 7 percent without stratification to the upper limit, is not turbid, is clear and transparent, has long stationary phase, and can completely satisfy the production, storage, transportation and use requirements of the methanol gasoline so as to solve the problem that the methanol gasoline generates phase separation because of the existence of water for a long time, and create beneficial conditions for generalization and popularization of the methanol gasoline.

Description

technical field [0001] The invention belongs to the field of alcohol gasoline substitute fuel additives, in particular to a methanol gasoline water-soluble agent. Background technique [0002] In order to save oil, various countries in the world have conducted a lot of research on methanol gasoline. With the rapid development of economy in our country, the number of automobiles has increased sharply, and the promotion and application of methanol gasoline is also deepening step by step. Many technical achievements have been obtained, and phased technical solutions have been obtained. However, at present, the most prominent problem in the storage and transportation of methanol gasoline is the phase separation of methanol and gasoline, which affects the normal use of methanol gasoline. When the air is humid or the temperature is low, methanol gasoline will absorb moisture and appear turbid and stratified after being placed in the air for 1-3 days. Most of the methanol will sin...

Problems solved by technology

For example, the invention patent of "alcohol fuel mutual solubility additive" with publication number CN101037625A discloses a component of n-heptamidine in its mutual solubility additive. For example, the invention patent of "a multifunctional fuel additive" with the publication number CN101285010A can solve the miscibility of existing alcohol fuels and have a great effect on the stability of alcohol fuels, but the high-carbon saturated alkanes or cyclic Composition of alkanes and higher alcohol ethers, there is a cost problem, which increases the cost of methanol gasoline; as the invention patent of "a kind of preparation method of M80-M90, E80-E90 alcohol-based vehicle fuel additives" with the publication number CN1916126A, it discloses mutual solvent The ingredient is oleic acid, which can have a miscible effect and promote the stable cycle of alcohol-based vehicle fuels, which can meet the requirements of use

But oleic acid is a kind of acidic macromolecule, adding in methanol gasoline is unfavorable to engine combustion; For example, in the invention patent of "gasoline power improver" with publication number CN1363646A, adding co-solvent to methanol gasoline can directly use ≤1% industrial Methanol, but in actual use, it is difficult to meet the cycle of production, application and storage; such as the invention patent of "a kind of water-containing methanol gasoline and its preparation method" with the publication number CN101285011A, the compatible additive used is the finished nonionic surfactant , although these commercial emulsifiers have good effects, the market purchase price is high; such as the invention patent of "methanol gasoline emulsification stabilizer" with the publication number CN1730624A, the stable period of stratification of methanol gasoline is long, which can meet the requirements of use, but the additive contains Trace metal sodium component, easy to residue and alkali corrosion after burning
