Description
Technical field
The present invention relates to the hydrocarbon containing fuels field, be specifically related to a kind of composite gasoline additive and preparation method thereof.
Background technology
Since advocating unleaded gasoline, methyl tertiary butyl ether (MTBE) is as the substitute products of lead salts such as tetraethyllead, and a lot of in the world countries are widely used as gasoline dope.But MTBE has the intensive smell, causes expiratory dyspnea, asthma, dizzy headache, insomnia and one's eyes became bloodshot and allergic symptom such as fash, and the carcinogenic possibility of potential is arranged, and the MTBE that leaks causes severe contamination to underground water resources.At present, also there is many countries to use ethanol, in Heilungkiang of China, Jilin, Liaoning, Henan, Anhui etc. economize the gasoline of ethanol also on probation as additive as gasoline dope.But be to use single ethanol additive, have following shortcoming: ethanol petrol vaporization poor performance, calorific value is low, power descends to some extent, oil consumption height, vapour pressure height, can occur that vapour lock is flame-out when day hot, storge quality difference etc., blend when reaching 10% when ethanol and gasoline, also can produce corrosive nature copper.
Diisopropyl ether (DIPE) is isopropyl ether again, chemical formula: (CH
3)
2CHOCH (CH
3)
2, be widely used in pharmacy, coating and paint cleaning aspect as important solvent.Dehydrated alcohol, chemical formula: (CH
3CH
2OH), be widely used in chemical industry, pharmacy, coating and paint cleaning aspect as important solvent.
Summary of the invention
For overcoming the above-mentioned defective of existing additive, the invention provides a kind of composite gasoline additive and preparation method thereof.Composite gasoline additive of the present invention comprises following component: ethanol and diisopropyl ether, and its each compositions in weight percentage ratio range is as follows: diisopropyl ether is 60～70%, ethanol is 30～40%.
Composite gasoline additive of the present invention by weight percentage preferably proportioning be: 62%～68% diisopropyl ether and 32%～38% ethanol.
The best by weight percentage proportioning of composite gasoline additive of the present invention is as follows: diisopropyl ether is 63%, and ethanol is 37%.
The main physical and chemical index of raw material of the present invention is as follows:
| Weight percent (%) | Boiling point (℃) | Reid vapour pressure (kPa) | Contain oxygen value | Octane value | |
| Dehydrated alcohol | ＞99.7 | 77.8 | 138.0 | 34.7 | 113.0 |
| Diisopropyl ether | ＞99.0 | 68.3 | 33.8 | 15.7 | 105.0 |
The preparation method of composite gasoline additive of the present invention is: at normal temperatures and pressures, the ethanol and the diisopropyl ether of above-mentioned weight proportion are mixed, stirring mixes it and gets final product.The preparation method of composite gasoline additive of the present invention does not have special requirement to temperature and pressure and container etc., only time get final product at normal temperature (promptly 15 ℃～35 ℃) normal pressure (promptly 1 about standard atmospheric pressure), container of material such as glass, plastics, iron all can realize preparation method of the present invention.The consumption of composite gasoline additive of the present invention in gasoline can be for adding the composite gasoline additive of the present invention of 10L in the gasoline of every 100L, specific practice is: earlier composite gasoline additive of the present invention is added in the fuel tank, and then add gasoline.
Composite gasoline additive of the present invention is compared with existing additive, has the following advantages:
1. Fa Ming composite gasoline additive, alcoholic acid contains oxygen value and octane value is all higher, add composite gasoline additive of the present invention, can effectively improve the octane value of different grades gasoline, octane value can reach the above standard of gasoline No. 97, improves the burning quality of gasoline, reduces the exhaust gas discharging amount, improve the capability of antidetonance, reduce engine shake and noise;
2. because diisopropyl ether has anti-freezing property and resistance toheat well, because the Reid vapour pressure of diisopropyl ether is lower, the gasoline that adds the diisopropyl ether blending can reduce the vapour pressure of gasoline, the cold start-up and the warming-up performance of automobile are improved, can effectively improve the phenomenon of the flame-out and cold start-up in winter of automobile vapour lock in summer, sparking is fast, easily start;
3. removing carbon effectively cleans whole oil piping system, protects oil thrower remarkably, reduces maintenance cost.Because composite gasoline additive is organic compound, and diisopropyl ether and ethanol all has good solubility property, and itself and gasoline compatible functional joins it in gasoline, can reduce the carbon deposit phenomenon of oil circuit, the cleaning of maintenance system;
4. the starting material of production diisopropyl ether are propylene and water, fluctuations in prices of raw materials is little, be not subjected to the ethanol market control, produce the alcoholic acid starting material and derive from jowar, sugarcane, corn etc., aboundresources is a renewable energy source, meet China's energy substitution strategy and renewable energy source developing direction, ripe safe and reliable on the production technology, suitable fully in China, have favorable economic benefit and social benefit;
5. the compound method of composite gasoline additive of the present invention is very simple, under room temperature and normal pressure, the ethanol and the diisopropyl ether of described ratio is mixed, and stirring mixes it and gets final product.
