Description

A kind of multifunctional fuel oil additive

technical field:

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

background technology:

In order to save energy, improve the combustion position of oil fuel, in oil fuel, often add additive to improve some some performance of oil fuel.Fuel dope and petroleum additive, be mainly used in gasoline, diesel oil, kerosene and oil fuel.By effect point, 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 improves some character of oil fuel really to a certain extent, but their function singlenesses, and can only improve a certain performance of oil fuel, other performances for oil fuel do not improve.So development one has multi-functional composite additive and just seems particularly important.At present, research and develop a large amount of fuel oil additives, but, but report is rarely had for compound fuel oil additive.

Summary of the invention

The object of the invention is to solve the shortcoming first having fuel oil additive function singleness, and invention a kind of multifunction additive, this additive be by several organism and inorganics allotment synthesis there is multi-functional fuel oil additive.This additive can make the smoke evacuation flue dust of oil fuel significantly reduce, and uncombined carbon particle significantly reduces, and CO quantity discharged reduces, and this additive not only greatly can 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 made up 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: the rare manganese tricarbonyl of methyl ring penta 2 15 parts;

Dialkyl diphenylamine 10 parts;

Sodium phosphate 10 parts;

Cetyl trimethylammonium bromide 15 parts.

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

(1) in the reactor being full of nitrogen, octane promoter is added: 10-15 part and static inhibitor: 5-10 part stirred at ambient temperature 15 minutes;

(2) cool to 0-5 DEG C, add oxidation inhibitor while stirring: 5-10 part and FLOW IMPROVERS: 10-20 part stirs 5 minutes;

(3) be warmed up to room temperature, continue stirring 15 minutes.

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

(1) in the reactor being full of nitrogen, add the rare manganese tricarbonyl of methyl ring penta 2 15 parts and sodium phosphate 10 parts of stirred at ambient temperature 15 minutes;

(2) cool to 0 DEG C, add dialkyl diphenylamine 10 parts while stirring and stir 5 minutes with cetyl trimethylammonium bromide 15 parts;

(3) be warmed up to room temperature, continue stirring 15 minutes.

Static inhibitor can reduce material or product surface resistance and volume resistance, and appropriateness improves electroconductibility in order to avoid electrostatic accumulation is caused danger; Oxidation inhibitor can prevent fuel oil viscosity from rising; Flow ability modifying agent of the present invention can improve the surfactivity of oil fuel, oil fuel is made to obtain composition dispersion, improve its efficiency of combustion, reduce CO quantity discharged, but and the flow ability modifying agent of not all or tensio-active agent, Sodium dodecylbenzene sulfonate etc. as conventional in petrochemical complex all cannot be applied in the present invention, and with the palmityl trimethyl ammonium chloride of cetyl trimethylammonium bromide structural similitude for time of the present invention, also without this effect.

Cetyl trimethylammonium bromide in white or Light yellow crystals body to Powdered, be soluble in Virahol, water soluble, during concussion, produce a large amount of foam, can have good coordinating with positively charged ion, nonionic, amphoterics.There is excellent infiltration, softening, emulsification, antistatic, the performance such as 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, emulsion pore forming material, tensio-active agent, analytical reagent, terylene real silk agent, leather fat, it is also for soldering flux, solder paster plays Action of Surfactant in producing, active strong, to bright spot, rosin joint, weldering electricity full (CTMAB), energy dissolved cell film, it is a kind of cationic detergent, there is the characteristic of precipitate nucleic acids and acidic polysaccharide from the solution of low ionic strength, under these conditions, 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 may be used for from producing the organism of mucopolysaccharide in a large number as prepared purify DNA plant and some Gram-negative bacteria (comprising some strain of E.coli).

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

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%.
