Description

A kind of multifunctional fuel oil additive

Technical field:

The invention belongs to the additive technology field, relate in particular to a kind of multifunctional fuel oil additive.

Background technology:

For save energy, improve the combustion position of oil fuel, tend to add additive to improve some some performance of oil fuel in oil fuel.Fuel dope is petroleum additive, is mainly used in gasoline, diesel oil, kerosene and oil fuel.By effect minute, mainly contain octane promoter, oxidation inhibitor, metal passivator, static inhibitor, wear-resistant rust-preventive agent, FLOW IMPROVERS etc., phosphoric acid salt or phosphate derivative are the main components of fuel dope, both can play wear-resistant rust inhibition, can play again anti-oxidant, anti-aging effect.

In recent years, people do extensive work for the research of fuel oil additive.But most additive has improved some character of oil fuel really to a certain extent, but their function singlenesses can only improve a certain performance of oil fuel, for other performances of oil fuel, do not improve.So, develop and a kind ofly there is multi-functional composite additive and just seem particularly important.At present, research and develop a large amount of fuel oil additives, still, for compound fuel oil additive, but rarely had report.

Summary of the invention

The objective of the invention is the shortcoming that the fuel oil additive function singleness is first arranged in order to solve, and a kind of multifunction additive of invention, this additive is the multi-functional fuel oil additive that has synthesized by several organism and inorganics allotment.This additive can make the smoke evacuation flue dust of oil fuel significantly reduce, and the uncombined carbon particle significantly reduces, and the CO quantity discharged reduces, and this additive not only can greatly reduce environmental pollution, and can improve rate of economizing gasoline.

Technical scheme of the present invention: multifunctional type fuel oil additive of the present invention is comprised of following component by mass:

Octane promoter 10-15 part, oxidation inhibitor 5-10 part, static inhibitor 5-10 part, FLOW IMPROVERS 10-20 part.

Octane promoter: the rare manganese tricarbonyl of methyl ring penta 2, tetraethyllead, ferrocene, octane promoter used in the present invention be above-mentioned any one.

Oxidation inhibitor: dialkyl diphenylamine, tetraethylenepentamine, spermine, oxidation inhibitor used in the present invention be above-mentioned any one.

Static inhibitor: sodium phosphate, sodium hydrogen phosphate, static inhibitor used in the present invention be above-mentioned any one.

FLOW IMPROVERS: cetyl trimethylammonium bromide, benzene sulfonic acid sodium salt, FLOW IMPROVERS used in the present invention be above-mentioned any one.

Optimize, above-mentioned octane promoter is: the rare manganese tricarbonyl of methyl ring penta 2;

Oxidation inhibitor is: dialkyl diphenylamine;

Static inhibitor is: sodium phosphate;

FLOW IMPROVERS: cetyl trimethylammonium bromide.

More excellent: 15 parts of the rare manganese tricarbonyls of methyl ring penta 2;

10 parts of dialkyl diphenylamine;

10 parts of sodium phosphates;

15 parts of cetyl trimethylammonium bromides.

The preparation method of above-mentioned a kind of multifunctional fuel oil additive, it comprises the steps:

(1) add octane promoter in being full of the reactor of nitrogen: 10-15 part and static inhibitor: stir 15 minutes under 5-10 part room temperature;

(2) cool to 0-5 ℃, add while stirring oxidation inhibitor: 5-10 part and FLOW IMPROVERS: 10-20 part is stirred 5 minutes;

(3) be warmed up to room temperature, continue stirring and get final product in 15 minutes.

Optimize, the preparation method of above-mentioned a kind of multifunctional fuel oil additive, it comprises the steps:

(1) add in being full of the reactor of nitrogen under 15 parts of methyl ring penta 2 rare manganese tricarbonyls and 10 parts of room temperatures of sodium phosphate and stir 15 minutes;

(2) cool to 0 ℃, add while stirring 15 parts of 10 parts of dialkyl diphenylamine and cetyl trimethylammonium bromides to stir 5 minutes;

(3) be warmed up to room temperature, continue stirring and get final product in 15 minutes.

Static inhibitor can reduce material or product surface resistance and volume resistance, and appropriateness improves electroconductibility in order to avoid static is accumulated causes danger; Oxidation inhibitor can prevent the viscosity rise of oil fuel; Flow ability modifying agent of the present invention can improve the surfactivity of oil fuel, making oil fuel obtain composition disperses, improve its efficiency of combustion, reduce the CO quantity discharged, but be not that all flow ability modifying agent or tensio-active agents all can, as Sodium dodecylbenzene sulfonate commonly used in petrochemical complex etc. all can't be applied in the present invention, and with the palmityl trimethyl ammonium chloride of cetyl trimethylammonium bromide structural similitude when of the present invention, also without this effect.

Cetyl trimethylammonium bromide be white in color or light yellow xln to Powdered, be soluble in Virahol, water soluble, produce a large amount of foams during concussion, can good coordination be arranged with positively charged ion, nonionic, amphoterics.There is the performances such as good infiltration, softening, emulsification, antistatic, biological degradability and sterilization.This product chemical stability is good, heat-resisting, fast light, withstand voltage, strong alkali-acid resistance.Purposes this product is natural, synthetic rubber, silicone oil and asphalt emulsifier, the static inhibitor of synthon, natural fiber and glass fibre, softening agent, the amendment of hair conditioner, phase-transfer catalyst, the emulsion pore forming material, tensio-active agent, analytical reagent, terylene real silk agent, leather fat, it is also for soldering flux, play Action of Surfactant in solder paster production, active strong, to bright spot, rosin joint, weldering electricity full (CTMAB), energy dissolved cell film, it is a kind of cationic detergent, characteristic with precipitate nucleic acids and acidic polysaccharide from the solution of low ionic strength, under this condition, protein and neutral saccharan are still stayed in solution, in the solution of high ionic strength, saccharan beyond CTMAB and protein and most of acidic polysaccharide forms mixture, just can not precipitate nucleic acids.Therefore, CTMAB can prepare purify DNA as plant and some Gram-negative bacteria (comprising some strain of E.coli) for the organism from a large amount of generation mucopolysaccharides.

And in above-mentioned introduction, and the no-trump cetyl trimethylammonium bromide is not applied in the tensio-active agent of chemical field by it for petrochemical industry.

The invention has the beneficial effects as follows: fuel oil additive prepared by the present invention is for different fuel oil, and it is the highest can reduce smoke evacuation fume amount decrement 36.4%, reduces uncombined carbon particle weight 48.1%, reduces CO quantity discharged 47.7%, rate of economizing gasoline improves 40.0%.
