| Commercially available many nitric ethers diesel oil that contains | 44.0 | 1.8 |
| Embodiment 1 | 44.8 | 2.5 |
| Embodiment 2 | 44.9 | 2.6 |
| Embodiment 3 | 45.4 | 3.1 |
The result of table 1 shows that diesel cetane-number additive provided by the invention can effectively improve diesel-fuel cetane number.
The cetane value of measuring the diesel samples that embodiment 1-3 makes by GB/T 386-91 method is estimated the stability of diesel cetane-number additive over time respectively, and compares with diesel oil that existing commercially available other many nitric ethers are cetane number improver.The results are shown in Table 2
Table 2
| Sample | The 1st day | The 10th day | The 20th day | The 30th day |
| Base oil | 42.2 | 42.2 | 42.2 | 42.2 |
| Commercially available diesel oil | 43.2 | 43.2 | 42.8 | 42.6 |
| Commercially available many nitric ethers diesel oil that contains | 44.0 | 44.0 | 43.8 | 43.2 |
| Embodiment 1 | 44.8 | 44.8 | 44.8 | 44.7 |
| Embodiment 2 | 45.2 | 45.2 | 45.1 | 45.1 |
| Embodiment 3 | 45.3 | 45.3 | 45.3 | 45.2 |
The result of table 2 shows, adopts the diesel samples that contains the ignition dope of many nitric ethers provided by the invention to present cetane value stability preferably.
From the result of table 1 and table 2 as can be seen, diesel cetane-number additive provided by the invention not only can effectively improve diesel-fuel cetane number, and and and the existing ignition dope that contains many nitric ethers compare, diesel cetane-number is remained unchanged for a long time, improved the stability of diesel cetane-number greatly.
Beneficial effect of the present invention is: improved cetane value, after synthetic diesel oil, diesel oil emulsification add this ignition dope, reached the standard of international diesel cetane-number, burning fully; Improved the stability of fuel oil, it is safer more abundant to burn, and the carbon distribution phenomenon of engine is reduced, and has increased work-ing life; Easy to use, consumption is less, reduces mechanical wear, and machine is not had corrosion; Operate at normal temperatures and pressures during preparation, technology is simple, and is easy to operate.
