Abstract
A kind of additive for stability of diesel oil, it is to be combined by tertiary amine and shielding phenol.This additive raw material is easy to get, and preparation is simple, can be used for improving the storage stability of straight-run diesel oil and secondary processing diesel oil.
Description
The present invention relates to a kind of additive for stability of diesel oil, or rather, relate to the composite additive that combines by two kinds of compounds, be used to improve the stability in storage of solar oil.
Along with crude oil becomes heavy day by day, the development of deep processing technology, the diesel oil stability problem is more and more outstanding, and particularly secondary processing diesel oil such as catalytic cracking diesel oil stability are poorer, and in storage process, color deepens very soon, and colloid and insolubles increase sharply.Insolubles and colloid that diesel oil forms directly influence its use properties, cause engine filters to stop up, and prime the fuel system can not normal fuel injection, influence oil atomizing, causes incomplete combustion, even form too much carbon deposit in engine, makes the nozzle obstruction.Therefore, for solving the problem of diesel oil fuel stability, several different methods occurred, a kind of method wherein adds additive exactly in diesel oil, and is rotten to suppress it, improves its stability.Propyl group urea composite additive with the second month in a season or uncle's aliphatic amide and the replacement of N-alkyl is proposed among the USP3139330, can suppress or reduce the sedimental formation of ignition internal combustion engine inlet system, but the ring urea component need just can make in this additive in higher temperature of reaction and long reaction times; USP4501595 introduces earlier by tetraethylenepentamine and Paraformaldehyde 96,2,6-di-tert-butylphenol generation condensation reaction, obtain phenol-aldehyde-amine condensation product again with contain the Succinic anhydried generation condensation reaction that polyisobutene replaces, final product can improve the diesel oil stability in storage, but this additive needs plurality of raw materials, and will make through secondary reaction; USP4648885 introduces a kind of with the N-(2-aminoethyl) piperazine, triethylenetetramine and N, the mixture of N-diethyl hydroxylamine is an additive, can stop diesel colour to deepen formation with particulate matter, but this composite additive only improves the stability in storage of straight distillation light diesel oil, range of application is narrower.
The purpose of this invention is to provide a kind of raw material and be easy to get, prepare simple composite additive, to improve the stability in storage of straight distillation light diesel oil, secondary processing solar oil or its mixing oil.
Additive for stability of diesel oil provided by the invention is to be combined by tertiary amine (components I) and shielding phenol (composition), and the weight ratio of tertiary amine and shielding phenol is 3～5: 1, and wherein the structural formula of tertiary amine is:

Composite additive of the present invention can prepare by following method: tertiary amine and shielding phenol are added in the blending container by a certain percentage, are heated to 40～60 ℃ under the normal pressure, stir the yellow thick liquid product that promptly obtained homogeneous transparent in 1～2 hour.
Described 2,6 ditertiary butyl p cresol, commodity are called T501, and Jinzhou petroleum chemical plant is produced; 2,6-di-t-butyl mixed phenol is that Beijing Chemical Factory No. 3 produces.This type shielding phenol is oil product oxidation inhibitor commonly used, and it can suppress the rotten and generation colloid of oxidized.
Described tertiary amine comprises N, N-dimethyl lauryl amine, N, N-dimethyl stearyl amine, N, N-dimethylcyclohexylamine, C

Additive for stability of the present invention can be used for straight-run diesel oil, catalytic cracking diesel oil or through the catalytic cracking diesel oil of soda finishing or the mixing oil of straight-run diesel oil and catalytic cracking diesel oil, its add-on is 50～150mg/L diesel oil.
Major advantage of the present invention is: composite additive all has improvement to the stability in storage of straight distillation light diesel oil and secondary processing solar oil, not only make the formation speed of oil product sediment become slow, and the inhibition gelationus increases, still can satisfy service requirements through storing contained sediment and colloid for a long time, the long-time storage test of oil tank in the open shows further that also additive of the present invention has good effect to suppressing the generation of sediment and gelationus; To straight-run diesel oil or through the catalytic cracking diesel oil of soda finishing, add additive of the present invention, the stability better effects if, after adding agent as the catalytic cracking diesel oil of soda finishing, not only suppressing sediment and gelationus forms, and the speed that color degenerates reduces, and normal temperature storage 50 days still can satisfy the colour specification requirement of first grade; Store the engine performance test that adds agent diesel oil by oil tank and show that additive of the present invention has no adverse effects to performances such as diesel motor power, oil consumption, row's temperature, smoke evacuations; Components of additives of the present invention is easy to get, and preparation technology is simple, but also has advantages such as oil soluble is good, stable.
Further describe characteristics of the present invention with example below.
