CN101851534B - Dissolution-assisting and upgrading agent for M30 methanol gasoline - Google Patents

Abstract

The invention relates to a dissolution-assisting and updating agent for methanol gasoline more than M30, 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 anti-swelling 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 methanol gasoline more than M30 prepared from the dissolution-assisting and updating agent is used, the parts of the engine do not need to be transformed, and the methanol gasoline more than M30 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 hydrotropy standard-increasing agent that is used for the above methanol gasoline of M30

Technical field

The invention belongs to the chemical industry class,, refer to the hydrotropy standard-increasing agent of the above methanol gasoline of a kind of M30 of being used for especially about a kind of hydrotropy standard-increasing agent that is used for methanol gasoline.

Background technology

Along with the process of world industryization constantly develops, receive 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 produce strong desire for methanol gasoline, the exploitation of ethanol vapor wet goods alcohol radical vehicle fuel hydrotropy standard-increasing agent and practical application; 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 improve.

Summary of the invention

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

The present invention is a kind of hydrotropy standard-increasing agent that is used for the above methanol gasoline of M30, is to be in harmonious proportion with various pure ether compounds, tensio-active agent, anticorrosion anti-swelling agent and nanometer nuclear-magnetism purification agent to form its various constitutive materials and numerical value is following by weight percentage:

Ethanol 2%-10%;

Ethyl acetate 5%-25%;

Virahol 5%-30%;

Amylalcohol 7%-45%;

Propyl carbinol 5%-15%;

YLENE 2%-8%;

MTBE 10%—45%?；

Methylal 10%-35%;

Nanometer nuclear-magnetism purification agent 3%-8%;

Emulsifying agent 1%-6%;

Anticorrosion anti-swelling agent 2%-10%;

Tensio-active agent 2%-4%;

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

Recipe step of the present invention is after adding various raw materials successively by above order, utilizes high magnetic cutting to carry and can mixer mixing evenly form, and under normal temperature condition, produces, 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 above methanol gasoline of M30 of this kind hydrotropy standard-increasing agent 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.
