Description
Background of invention
Invention field
The present invention relates to chemical technology, particularly relate to liquid composition, comprise hydrocarbon fuel composition, for example low-sulfur diesel-oil and low-sulphur oil fuel composition and lubricant, machine oil for example, hydraulic liquid, transmission fluid, machining oil, synthetic oil and composition thereof.
Correlation technique is discussed
Liquid hydrocarbon fuels generally comprises nearly 40, the sulphur of 000ppm.These sulphur are served required character to fuel tape.For example, the engine section of sulphur for rolling, rotating or slide as piston ring and liner, petrolift and injection system, provides high lubricity.But sulphur also has important disadvantages.In engine exhaust with a large amount of sulfurous gas (SO
2) and the sulphur that exists of deleterious particulate form caused environmental problem.Because a large amount of SO are arranged
2The use that is not widely used or is under an embargo of particulate and discharge, diesel engine in many big cities.
Therefore, exploitation low-sulfur hydrocarbon fuel composition be for the time demand very of a specified duration.For example, No. 2 diesel oil of low-sulfur comprise about 500ppm sulphur usually, and carried out numerous trials with further minimizing sulphur content to about 300ppm or still less.Unfortunately, the removing of sulphur has reduced the lubricity of diesel oil, has quickened the wearing and tearing of fuel system and combustion chamber components.When removing sulphur from fuel, high friction and wear appears in the sliding surface of fuel delivery system, and causes catastrophic fault.
Boric acid is safe to environment, cheap, and the uncommon ability that improves sliding metal surface friction resistant and wear resistance is arranged.The U.S. Patent No. 5,431,830 of Erdemir discloses to grease, adds boric acid in the oils etc. to improve oilness.Oilness is to prolong the engine of various dependence lubricants and the fundamental in mechanical part work-ing life, and various lubricants are as grease and oils based on oil, synthetic oil, mineral oil, silicone oil, machining oil, transmission fluid, hydraulic liquid etc.This patent proposes the boric acid particle under high pressure and friction gravitation, and load-bearing surface interacts so that remarkable elasticity and load bearing capacity to be provided.Crystallization boric acid particulate laminate structure is relatively sliding with comparalive ease, and can reduce friction and wear and tear.
Boric acid is crystalline compound, is insoluble to hydro carbons, as grease and oils.Because the viscosity of grease and oils, Erdemir patent are told us boric acid can be simply by using conventional equipment and technology to be distributed in grease and the oil.This patent also discloses the solid polymer that is combined with boric acid in the polymer architecture.This patent does not propose boric acid and can join in the low-sulfur hydrocarbon fuel to improve its performance.This patent does not propose a method for preparing stable boric acid suspension in liquid hydrocarbon fuels or in any other low viscous hydrocarbon medium like this yet.
The U.S. Patent No. 3,929,800 of Horowitz discloses polymerization simultaneously and the grafted monomer method to liquid hydrocarbon, comprises the various performances of viscosity with improvement.Be disclosed in the liquefied hydrocarbon of Horowitz patent and back pyrolysis gasoline arranged, catalytic pyrolysis cut and lubricating oil.This patent does not propose to add boric acid in liquid hydrocarbon, or is modified in those hydrocarbon and forms the method for stablizing microgranular boric acid suspension.
Therefore, still be starved of now at various engine parts, for example petrolift and injection system provide high lubricity and low wearing and tearing, non-environmental-pollution (being derived from the use of low-sulfur fuel) and liquid hydrocarbon fuels composition cheaply.The stabilising liq suspended substance that also need in hydrocarbon fuel and lubricant, contain microgranular boric acid.The present invention has satisfied these demands, and related advantages also is provided.

At last, add the grafting initiator, for example ferric sulfate or silver salt.Suitable silver salt comprises Silver Nitrate, Silver monoacetate, Sulfuric acid disilver salt, silver carbonate and silver perchlorate.Silver perchlorate is preferred grafting initiator, because it is dissolved in the liquid hydrocarbon fuels such as diesel oil.
The grafting initiator concentration can change within a large range, but preferably between about 0.0001～about 0.01 per-cent.For economic aim, preferably its quantity is about 0.001 per-cent or lower.
When being stirred, mixture begins reaction under room temperature and normal pressure, until the concentrated suspension liquid of the liquid hydrocarbon that forms boronic acid containing-chemical graft.Adopt this method might be in sulphur content less than 40, the liquid hydrocarbon fuels of 000ppm, for example sulphur content is less than 500ppm, or less than 300ppm, or even not in the liquid hydrocarbon fuels of sulfur-bearing, prepare spissated boric acid suspension.This method can also be diluted to concentrated solution and contain about 10ppm～about 50,000ppm (in finished product liquid hydrocarbon fuels weight), and more preferably from about 30ppm～about 5, the finished product liquid hydrocarbon fuels of the microgranular boric acid of 000ppm.Surfactant concentrations is preferably about 2ppm～about 6ppm in the finished product hydrocarbon fuel.Even under multiple potential instability condition, concentrated solution and finished product hydrocarbon fuel all keep stable.For example, boric acid all keeps suspended state in about-30～150 temperature range, and can stablize and deposit 1-2.And, when finished product liquid hydrocarbon fuels composition burns, provide remarkable oilness in oil engine, and reduce the wearing and tearing of internal combustion engine component, prevent corrosion simultaneously, and improve the economic benefit of fuel to a certain extent.In addition, when finished product liquid hydrocarbon fuels composition burns in oil engine, compare, reduced the discharging of particulates emission and gas (being sulfurous gas, carbonic acid gas) with conventional liquid hydrocarbon fuels.
Above-mentioned example is in order further to illustrate the present invention, and unrestricted the present invention.Unless offer some clarification in addition, all per-cents all are basic calculation with weight.
