| titleOfInvention | Cetane number improver and preparation method thereof |
| abstract | The present invention provides a kind of cetane number improver and preparation method thereof, and the preparation method of the cetane number improver, comprises the following steps：To equipped with adding the concentrated sulfuric acid and urea and ammonium sulfate in blender, thermometer and dropping funel flask, the temperature of control loop water-bath, is added dropwise a certain amount of 65% concentrated nitric acid under high degree of agitation；After stablizing, ethylene glycol is slowly added dropwise at this temperature；Fully after reaction, reaction solution is poured into separatory funnel, stratification, the ester liquid on upper strata is light yellow；Lower floor's acid solution is extracted by several times with chloroform, and extract is merged with ester liquid, neutrality is neutralized to sodium carbonate liquor, is finally dried with anhydrous sodium sulfate；Decompression steams chloroform, you can obtains the dinitroglycol of higher degree.This method prepare to cetane number improver add in people's diesel oil, may participate in the degeneration branching reaction before hydrocarbon fuel molecule catches fire, effectively change the elicitation procedure of chain reaction, can shorten the chemical delay period of diesel oil, improve Cetane number. |
