Abstract

The invention relates to a dissolution-assisting and updating agent for vast-scale methanol gasoline, which belongs to chemical industry. The dissolution-assisting and updating agent is formed by blending all kinds of alcohol ether compounds, a surface active agent, an anticorrosive agent and a nano nuclear magnetic detergent and then adding benzotriazole (BTA) into the prepared solution, wherein the concentration of the solution is prepared in the proportion of 100 to 500 ppm. In the dissolution-assisting and updating agent, all kinds of compounds can be obtained easily; when the vast-scale methanol gasoline prepared from the dissolution-assisting and updating agent is used, the parts of the engine do not need to be transformed, and the vast-scale methanol gasoline prepared from the dissolution-assisting and updating agent has high alcohol-oil compatibility, high cold starting property, high combustion performance and obvious substitution effect; and the composite solvent has the advantages of no environmental pollution and high application value and economic value compared with the conventional unleaded gasoline.

Description

A kind of be used for large-proportion methanol gasoline help the appearance standard-increasing agent

Technical field

The invention belongs to the chemical industry class, relevant especially a kind of be used for large-proportion methanol gasoline help the appearance standard-increasing agent, what refer to large-proportion methanol gasoline that a kind of M30 of being used for is above especially helps the appearance standard-increasing agent.

Background technology

Along with the process of world industryization constantly develops, be subjected in the natural crude oil resource under the limited case of reserves, the exploitation of novel automobile alternative fuel has become the problem that countries in the world are all very paid close attention to.People utilize the alcohol radical vehicle fuel of organic raw material exploitation in recent years, offer a kind of new Energy resources of people, and have very wide application prospect.But how to use methanol gasoline, ethanol vapor wet goods alcohol radical vehicle fuel better, make people help exploitation of appearance standard-increasing agent and practical application to produce strong desire for methanol gasoline, ethanol vapor wet goods alcohol radical vehicle fuel, so that solve problems such as using being short of power of producing behind methyl alcohol, the ethanol, oil consumption increase, low-temperature stratification and cold start-up difficulty in the alcohol radical vehicle fuel, but the present similar additive product of Application and Development, on functions of use, all there are various deficiencies, do not have use properties widely.The problem of above-mentioned existence needs further to be improved.

Summary of the invention

The object of the present invention is to provide a kind of be used for large-proportion methanol gasoline help the appearance standard-increasing agent; the large-proportion methanol gasoline that particularly a kind of M30 of being used for is above help the appearance standard-increasing agent; overcome the shortcoming of other solubility promoter; solved being short of power that the alcohol radical vehicle fuel occurs preferably; oil consumption increases; the cold start-up difficulty; the hot gas resistance; low-temperature stratification; poor stability; the corrosion swelling; multinomial technical barrier such as high temperature lubricating; the Vehicular methanol petrol that uses this solubility promoter to produce; suitability of fuel is strong; sufficient combustion; and can reduce obnoxious flavour CO in the motor exhaust; the discharging of CH helps environment protection more.

The present invention is a kind of be used to prepare large-proportion methanol gasoline help the appearance standard-increasing agent, be to be in harmonious proportion with various pure ether compounds, tensio-active agent, anticorrosive agent and nanometer nuclear-magnetism purification agent to form, its various constitutive materials and numerical value is as follows by weight percentage:

Ethanol 2%-10%;

Ethyl acetate 5%-25%;

Virahol 5%-30%;

Amylalcohol 7%-45%;

Propyl carbinol 5%-15%;

Dimethylbenzene 2%-8%;

MTBE 10％-45％；

Methylal 10%-35%;

Nucleus magnetic resonance liquid 3%-8%;

Emulsifying agent 1%-6%;

Anticorrosion anti-swelling agent 2%-10%;

Tensio-active agent 2%-4%;

The BTA that adds 100-500ppm in according to the solution after the above-mentioned desired formulated again is finished product.

Recipe step of the present invention is after adding various raw materials successively by above order, utilizes the cutting of high magnetic to carry can mixing tank to mix to form, and produces under normal temperature condition, and must keep fire away.

Product standard: grey emulsion liquid, proportion: 0.80-0.88; Boiling point: 178-182 degree; Zero pour :-37.8 degree; Flash-point: (opening agar diffusion method) 86.9 degree; Spontaneous ignition temperature: 536 degree; Limits of explosion: (volume) 1.37-11.8; Existent gum: smaller or equal to 6; Copper corrosion: smaller or equal to 1; Detection method: go up the detection rules detection of standard according to this according to gasoline.

The invention has the advantages that:

1, classes of compounds of the present invention obtains easily.

2, need not transform engine parts with the large-proportion methanol gasoline of this kind solubility promoter configuration, good pure oil phase dissolubility and cold startability are arranged, have good burning performance, substitution effect is obvious.

3, combination solvent of the present invention is free from environmental pollution, and comparing with the existing white gasoline of using has higher using value and economic worth.
