Description
Technical field
The present invention relates to the additive that petroleum products uses, specifically isobutenyl acid amides oil/fat composition in different heptan and preparation method.
Background technology
For many years, in the many metals and nonmetal octane rating promoter agent that people tested, manganese base organic compound is one of best octane rating promoter agent of quality, is called for short MMT.MMT can be in white gasoline boosting of octane rating effectively, and the effect that alleviates engine scuffing in addition; But its maximum shortcoming is the cost height, approximately is four times of plumbous octane rating promoter, and group and it are destroyed the effect of purifying vehicle exhaust in addition, make it in use have dispute, the more important thing is that adding the back octane value can only increase by 2～2.5 units.Life-time service also certainly will cause the metal accumulation, causes that sparking plug is malfunctioning, causes defectives such as the blast gate lost of life and combustion chamber deposit increase.
People use pure organic compound as octane rating promoter in research again, such as some countries produce a kind of octane rating promoter that is called for short MMA that uses in Europe, goodish anti-knocking property are arranged, but its cost are higher, in use also is restricted.Its toxicity is penetrated into underground, causes water to pollute and brings defectives such as harm to the mankind.
State Bureau of Technical Supervision has issued GB17930-1999 from December, 1999, particularly since the new standard GB17930-2006 that issued in 2006, the refinery of all parts of the country, each system, different device all takes different approach to reach the requirement of new gasoline standard.Because historical reasons, 85% of China's oil refining apparatus is a catalytic cracking unit.The octane value index of white gasoline is difficult to reach high standardization, and the olefin(e) centent severe overweight, and more problem is the straight-run spirit surplus, is difficult to become fully standard substance.The defective that is difficult to obtain ideal effect when simple employing processing and accord method
Summary of the invention
Goal of the invention of the present invention provides a kind of nontoxic, pollution-free, no specific peculiar smell, and addition is few, improve gasoline octane rating promotor performance, the simple isobutenyl acid amides of adding technology oil/fat composition in different heptan.
Another goal of the invention of the present invention provides the preparation method of isobutenyl acid amides fat in different heptan.
In order to overcome the deficiencies in the prior art, technical scheme of the present invention is to solve like this:
Its marked improvement of isobutenyl acid amides oil/fat composition in different heptan be said composition by mass ratio by 70～75 parts of tetrahydrofurfuryl alcohols, 13 parts～25 parts crotonamides, 5 parts～12 parts ethyl acetate, 0.005 part～0.008 part oxidation inhibitor, 0.005 part～0.008 portion sanitas is formed.
Described oxidation inhibitor is 2,6 ditertiary butyl p cresol, 4,4 methylene-biss-2,6 di t butyl phenol.
Described sanitas is an isothiazolinone, 4-phenyl-1-butanols.
A kind of preparation method of isobutenyl acid amides fat in different heptan, undertaken by following step:
A, take by weighing tetrahydrofurfuryl alcohol by mass ratio, crotonamide, ethyl acetate, 2,6 ditertiary butyl p cresol, isothiazolinone;
B, tetrahydrofurfuryl alcohol is added to reaction kettle for vacuumizing, its vacuum tightness is 0.3Mpa～0.5Mpa, and the pumpdown time, reactor was warmed up to 70 ℃～75 ℃ ± 1 ℃ for till the tetrahydrofurfuryl alcohol agent adds;
C, add crotonamide and ethyl acetate again, began to stir 25～35 minutes, be cooled to about 25 ℃ by water cooler;
D, add T501 or 2,6 ditertiary butyl p cresol, isothiazolinone again and stirred 15～25 minutes;
Above-mentioned tetrahydrofurfuryl alcohol content 〉=99.00%.
A kind of isobutenyl acid amides oil/fat composition in different heptan, its marked improvement be said composition by mass ratio by 65 parts～70 parts tetrahydrofurfuryl alcohols, 22 parts～30 parts crotonamides, 5 parts～7 parts ethyl acetates, 0.003 part～0.008 part 2, the 6-ditertbutylparacresol, 0.003 part～0.008 part composite composition of sanitas isothiazolinone.
Described oxidation inhibitor is 2,6 ditertiary butyl p cresol, 4,4 methylene-biss-2,6 di t butyl phenol.
Described sanitas is an isothiazolinone, 4-phenyl-1-butanols.
The preparation method of above-mentioned composition is identical.
The present invention compared with prior art, nontoxic, pollution-free, no specific peculiar smell, addition is few, raising gasoline octane rating promotor performance is remarkable, adding technology is simple, do not contain the heavy metal composition, can not bring new pollution to environment, can petroleum naphtha, virgin oil, catalyzed oil, straight run catalysis be in harmonious proportion the underproof base oil of wet goods octane value modified be 90#, 93#, 95#, 97#, 98# gasoline, gasoline octane rating promotor is brown oily transparent liquid, density is 970～990Kg/m
3, condensation point is not higher than-50 ℃, and boiling point is 180 ± 5 ℃.Group and production technique is simple, cost is low, have oil saving and pollution reducing, the effect that reduces the engine fuel oil system settling, alleviate engine scuffing.
Data show that its effect is higher than MMT and MTBE far away in the following table.This point is had petroleum naphtha, and the user of lightweight wet goods low octane rating oil product produces the high-octane rating oil product and opened up new way.
This product not only has good susceptibility to low octane rating oil, and group and the high-octane oil product of centering all have effect clearly.
Following table is listed in the influence of the susceptibility in the various different octane oil products
| Base oil RON | Addition % | Add back RON | Increase RON |
| ??69.2 | ??3.0 | ??91.2 | ??22 |
| ??74.4 | ??2.3 | ??90.2 | ??15.8 |
| ??78 | ??1.8 | ??90.6 | ??9.6 |
| ??81 | ??2.0 | ??90.4 | ??12.4 |
| ??89.2 | ??1.0‰ | ??93.2 | ??4 |
| ??90.5 | ??1.1‰ | ??95.2 | ??4.7 |
Data show that the present invention will have very great help to the gasoline that those can't reach No. 90 oil product labels in the table, and domestic oil product has been tending towards high standardization, and the needs of high grade oil are more and more.
The present invention calls in certain straight-run spirit in catalytically cracked gasoline, its olefin(e) centent is reduced in 35%, the octane value of mixed oil also descends thereupon, adds a certain amount of 1022 octane rating promoters again and can make the olefin(e) centent conformance with standard, and octane value also can reach standard.
Following table is two kinds of test-results of transferring oily scheme
1. normal pressure virgin oil: catalyzed oil=1: 2; The mixed oil octane value is 80 olefin(e) centents 27%.
Add promotor 1022/1023 back gasoline octane rating such as following table
| Add additive | Add-on | ??RON | ??MON | Increase RON | Increase MON |
| ??JH1022 | ??0.85‰ | ??84 | ??76 | ??2.8 | ??2.8 |
| ??JH1022 | ??1‰ | ??86.2 | ??78.4 | ??3.1 | ??3.3 |
| ??JH1023 | ??2％ | ??93.2 | ??82.4 | ??13.2 | ??10.6 |
| ??JH1023 | ??3％ | ??90.2 | ??80.3 | ??19.2 | ??17.5 |
Data show in the table, and this kind scheme adds 1.5% promotor, can obtain qualified product.
2. catalytic reforming and catalytic gasoline were adjusted to RON89.6 by 2.5: 1, added 1022 octane rating promoter agent 1 ‰, were adjusted to RON93# (reformation RON89, favourable reformation elastic operation also can improve yield of gasoline 3.5～4%).
