Abstract
The invention relates to lubricant formulations and methods of lubricating a combustion system to achieve improved emissions catalyst durability. Different zinc dialkyldithiophosphate (ZDDPs) exhibitdifferent volatilities and have different effects on automotive emissions control catalysts. The ZDDPs and their respective decomposition fragments that have low volatility will have a correspondinglylower detrimental effect on combustion emissions control systems, because there are simply fewer phosphorous atoms that will pass through the combustion system to reach the emissions control system.Specifically, it has been discovered that ZDDPs that contain a significant fraction of MIBC ZDDP exhibit significantly lower volatility than other ZDDPs.
Description
Technical field
The present invention relates to a kind of lubricant formulations and method of lubricated firing system, in the emission control systems related, to obtain improved emissions catalyst durability with firing system.Especially, described method relates to the predetermined phosphor-included additive that uses relatively low quantity in lubricant, and the poisoning of emission control catalyst is minimized.The present invention also relates to the detection that TEOST MHT catches volatile matter, to select special phosphor-included additive, its emission control catalyst that produces minimum quantity is poisoned.
Background technology
Phosphorus is a kind of known element that is found and is attached to the lubricant compositions that is used for firing system.Lamentedly, can poison the catalyst component of emission control system from the bag phosphorated discharge of firing system.Especially, can poison these catalyzer by volatilization or burning seepage from the phosphorus discharge of lubricant, thereby reduce efficient or ability that exhaust catalyst reduces or transform deleterious firing system discharging.For example for many years, from the volatilization of the phosphorus of engine oil and by the combustion chamber, and the catalyst body that is deposited on car subsequently fastens, thereby makes the automobile emission Controlling System lose efficient.Therefore,, there has been a kind of trend, required to reduce the quantity of phosphorus in fresh engine oil as the CCMC engine oil specifications of new introducing.
Summary of the invention
Therefore, an object of the present invention is to help to solve the poisoning of catalyst problem that the phosphorus burning is caused in firing system.Further, an object of the present invention is to special type zinc dialkyl dithiophosphate (ZDDP) give special concern, described zinc dialkyl dithiophosphate can be used as additive in lubricant compositions.In addition, the special zinc dialkyl dithiophosphate method for compositions of described selection can combine with the industrial limitations to the lubricant compositions phosphorus content and use, with help to control with the minimum emissions Controlling System in the catalyzer phosphorism.
Embodiment
Have been found that different zinc dialkyl dithiophosphate (ZDDPs) demonstrates different volatility and the Vehicle Emission Control catalyzer is had different influences.In other words, as the result of normal loss in the base chamber and use, ZDDP will decompose.Therefore different ZDDP molecules will resolve into different sheet segment molecules.Described decomposition fragment can have different basically volatility levels.If zinc dialkyl dithiophosphate and their corresponding fragments of decomposing have low volatility, correspondingly it will have littler disadvantageous effect to the burning and exhausting Controlling System, because seldom phosphorus atom is only arranged by described firing system and arrive described emission control systems.In other words, the volatility of described harmful molecule is low more, via engine seepage or simple combustion and just few more by the molecule of firing system.On the contrary, if ZDDP and its corresponding fragment of decomposing have high volatility, then the molecule number by described firing system can improve, thereby causes the raising to described emission control catalyst murder by poisoning.
Zinc dialkyl dithiophosphate is a kind of well-known lubricant additive, and it is used in various types of explosive motors.Zinc dialkyl dithiophosphate be comprised in purpose be to improve at least resistance to wear and the mixed additive of antioxidation property in.But in fact, term " zinc dialkyl dithiophosphate " is meant many different alternative molecules.Difference between described molecule mainly is at different alkyl component and the described alkyl component relative space relation around the phosphorus molecule.Different zinc dialkyl dithiophosphates can have different performance performances in lubricant.
In brief, zinc dialkyl dithiophosphate forms by alcohols is combined with thiophosphate.Zinc dialkyl dithiophosphate is usually by being used for synthesis technique to provide the alcohol of alkyl to describe to described zinc dialkyl dithiophosphate molecule.Therefore for example, " primary (primary) " zinc dialkyl dithiophosphate is formed by primary alconol, it includes but not limited to, nonylcarbinol, n-Octanol, 2-ethyl-1-hexanol, 1-hexanol, 4-methyl-1-pentene alcohol, 2-methyl isophthalic acid-propyl alcohol, 1-amylalcohol, 1-butanols, 1-propyl alcohol and composition thereof.Similarly, " secondary (secondary) " zinc dialkyl dithiophosphate is formed by secondary alcohol, and it includes but not limited to, 2-propyl alcohol, 2-butanols, 2-amylalcohol, 4-methyl-2-amylalcohol, 2-hexanol, sec-n-octyl alcohol and 2-decyl alcohol and composition thereof." aryl " zinc dialkyl dithiophosphate comprises the zinc dialkyl dithiophosphate that is formed by phenol, butylation phenol, 4-dodecyl phenol and 4-nonyl phenol and composition thereof.In lubricant formulations, different zinc dialkyl dithiophosphates is usually mixed to obtain the different benefits of described dissimilar zinc dialkyl dithiophosphate.
Be surprised to find that a kind of its signal portion or all demonstrate than the significantly lower volatility of other zinc dialkyl dithiophosphate by the formed zinc dialkyl dithiophosphate of methyl isobutyl carbinol (MIBC or 4-methyl-2-amylalcohol).Usually, known zinc dialkyl dithiophosphate compound can experience rearrangement reaction when being heated, and it comprises esterification and β division.Esterification produces new neutral or metal-free phosphotriester.Can predict the neutral phosphate compound and have more volatility than phosphate metal salt.It is generally acknowledged around the sterically hindered of oxygen part of zinc dialkyl dithiophosphate and can reduce the speed that ester forms.Suppose since in methyl isobutyl carbinol part, exist sterically hindered, described methyl isobutyl carbinol type zinc dialkyl dithiophosphate demonstrates low volatility.
All be that the zinc dialkyl dithiophosphate mixture of methyl isobutyl carbinol type zinc dialkyl dithiophosphate (MIBC ZDDP) or the methyl isobutyl carbinol type zinc dialkyl dithiophosphate that comprises signal portion is compared with other zinc dialkyl dithiophosphate and demonstrated relative low volatility, this is a great discovery.As a result, all be that methyl isobutyl carbinol type zinc dialkyl dithiophosphate will have still less disadvantageous effect to exhaust catalyst than other zinc dialkyl dithiophosphate.This means that the phosphorus content to the relative estimation of the disadvantageous effect of discharging and usually existence is not directly related.Therefore, before determining any demand, must in performance test, assess the true effect of zinc dialkyl dithiophosphate for phosphorus content lower in lubricant.
Except that methyl isobutyl carbinol type zinc dialkyl dithiophosphate, believe that the zinc dialkyl dithiophosphate that may have other has lower volatility relatively than conventional zinc dialkyl dithiophosphate.The zinc dialkyl dithiophosphate of other low volatility can comprise by the 2 ethylhexyls alcohol or by the prepared zinc dialkyl dithiophosphate of mixture of methyl isobutyl carbinol and other more high molecular secondary alcohol for example of high-molecular weight secondary alcohol more.
Other lubricant additive component can similarly influence the volatility of the described P contained compound in the lubricant compositions.In an example, comprise the sanitising agent of calcium sulphonate, when this washing composition uses with the zinc dialkyl dithiophosphate additive, can reduce the deleterious phosphorism of described emission control systems catalyzer in lubricant compositions.When recognizing these benefits, can not think that the use of sanitising agent will have any discrepant influence for phosphorism.Therefore, identify still less volatile zinc dialkyl dithiophosphate and will outside the use sanitising agent, have extra or independently useful influence.Other chemistry adds the deleterious effect that preparation also may reduce phosphorism usually, but can not think that any of these effect meeting has influence distinctively to the different zinc dialkyl dithiophosphates that may use.Therefore, be the most accurate analysis to the analysis of zinc dialkyl dithiophosphate in the lubricant formulations that does not for example contain detergent additive component to the beneficial effect of selecting low volatility zinc dialkyl dithiophosphate component.
The physical result that the low volatility of described methyl isobutyl carbinol type zinc dialkyl dithiophosphate is described is displayed in a plurality of tests, comprises phosphorus retention test and TEOST MHT-4 test.
The phosphorus retention test
Described phosphorus retention test has been measured the concentration that is deposited in phosphorus in the used lubricant after Sequence III G test in 100 hours.The concentration of phosphorus in described used oil and the concentration of phosphorus in green oil have been compared in described test.It is as follows to be used to calculate the formula that phosphorus keeps: PR100=([fresh calcium]/[calcium at 100 hours] * ([phosphorus at 100 hours]/[fresh phosphorus]) * (at 100 hours phosphorus/fresh phosphorus).This equation has been proofreaied and correct for the phosphorus concentration that increases the volatility base-material loss of measuring by calcium concn.Described phosphorus retention analysis is important for lubricant test, because all oils will be distinguished according to the phosphorus amount that they discharge.Note that phosphorus that described oils discharges is last burned and be discharged into logistics on the catalyzer in the described emission control systems.
All be that methyl isobutyl carbinol type zinc dialkyl dithiophosphate demonstrates average about 87% phosphorus reservation.The phosphorus of blended zinc dialkyl dithiophosphate keeps average out to 81%.The phosphorus of secondary zinc dialkyl dithiophosphate keeps average out to 78%.By these results obviously as can be known, when using whole methyl isobutyl carbinol type zinc dialkyl dithiophosphates, the amount that is retained in the phosphorus in the described lubricant raises significantly, and in an example, the scope that phosphorus keeps is greater than about 85%.
TEOST?MHT-4
TEOST MHT-4 test is a kind of lubricant industry test of standard, and it is used for the oxidation of engine evaluated finish and forms the carbonaceous sediment feature.Described test is designed to simulate high temperature (285 ℃) deposition in the ring belt zone of engine.The core of described test is to obtain the sedimentary weight that forms on the depositor rod of resistive heating, wherein said depositor rod remains within the sleeve pipe, and big gauging is crossed described rod with the velocity flow of 0.25 gram/minute.Control the temperature of described rod by thermopair.The catalyzer that use is made up of 3/2/1 iron, lead and tin promotes the forced oxidation on the described oil.Oxidation in described test is measured by the sedimentary quality that forms on described rod.
All be that the resulting product of methyl isobutyl carbinol type zinc dialkyl dithiophosphate is about 25 milligrams after measured.Expectation has less than about 30 milligrams test product.By primary, the zinc dialkyl dithiophosphate of other type of being formed of secondary, mixing and dialkyl aryl zinc dithiophosphate produces 35-70 milligram deposition in described TEOST MHT-4 test.In the standard operation of described TEOST MHT-4 test, volatile fraction is collected.These parts will be analyzed phosphorus content by ICP below.
TEOST MHT-4 volatile matter icp analysis
The selection that produces volatile phosphorus zinc dialkyl dithiophosphate chemicals minimum or the reduction amount can be realized by the check that TEOST MHT-4 catches volatile matter.The volatile matter of catching in described TEOST test stands inductively coupled plasma (ICP) to be analyzed to measure the amount of volatile phosphorus compound, and it has represented the degradation production of described zinc dialkyl dithiophosphate.Described ICP test is described by testing regulation ASTM D5185.In brief, with sample dissolution in appropriate solvent matrix, thereby and it is delivered to atomizer with peristaltic pump tiny spraying is incorporated in the highly charged argon plasma.Element in the described sample of energy desolvation, atomize and ionization of described plasma body.Owing to the excited state of described element and atom and the ion that takes place to low-energy state more that fail subsequently change and can be observed in ultraviolet and visible spectrum.Each element that is present among the sample is luminous at discrete wavelength, and it is separated by echelon, and focuses on the solid-state CID detector.The emissive porwer of every kind of element can be compared with the emission of the standard model of the element that comprises concentration known in the sample, so that quantitative assay to be provided.
Test is similarly being carried out on the lubricant formulations.For comprising the fully preparation finish of 500ppm, analyze by icp analysis from the described volatile matter of TEOST test, and its result is as follows from the phosphorus of zinc dialkyl dithiophosphate:
TEOST MHT-4 volatile matter is analyzed
Icp analysis concentration ppm
| The ZDDP type | The alcohol type | Volatility phosphorus | The MHT-4 deposition |
| Secondary ZDDP | ??C3/C6 | ??153 | ??36 |
| Uncle ZDDP | ??C4/C51C8 | ??256 | ??71 |
| Mix ZDDP | ??C3/C4/C8 | ??200 | ??71 |
| Secondary ZDDP | The C8 high base number | ??86 | ??63 |
| Secondary ZDDP | Whole MIBC C6 | ??33 | ??27 |
| Aryl ZDDP | Fragrance | ??6 | ??76 |
C4 refers to the butyl carbochain
Prove that as above-mentioned test the order of the volatility phosphorus of described crankcase zinc dialkyl dithiophosphate is as follows: dialkyl aryl zinc dithiophosphate＞whole methyl isobutyl carbinol type C6 zinc dialkyl dithiophosphate＞C8 Bogao base number zinc dialkyl dithiophosphate＞secondary zinc dialkyl dithiophosphate＞mixing zinc dialkyl dithiophosphate＞uncle C4/C5/C8 zinc dialkyl dithiophosphates.Described dialkyl aryl zinc dithiophosphate demonstrates the more phosphorus part of low volatility, and simultaneously, its MHT-4 deposition value is higher relatively.Best result not only has the phosphorus part of low volatility but also has low deposition value.Preferably, zinc dialkyl dithiophosphate should have phosphorus content less than the volatile fraction of about 100ppm and less than about 30 milligrams of sedimental low MHT-4 test products.Therefore, clearly, the TEOST volatile matter of described use icp analysis test can be used as a kind of specification qualitatively, selects to have exhaust catalyst is improved or the zinc dialkyl dithiophosphate of the influence dwindled.
From the benefit to maximum the discovery of low volatility zinc dialkyl dithiophosphate is the lubricant of low total phosphorous.Use is greater than 1, and the zinc dialkyl dithiophosphate of the historical concentration of 000ppm will become nonsensical to the discussion of described phosphorus component relative volatility, this be because so many phosphorus its all be enough to poison emission control catalyst down in that any volatile water is flat.Yet if a kind of lubricant has 800ppm, or in another example, less than 700ppm, or further alternatively, less than the phosphorus of 600ppm, the volatility of described reduction can bring significant wearing quality to improve the preservation of described emission control catalyst.
The foregoing description relates to all or whole basically methyl isobutyl carbinol type zinc dialkyl dithiophosphates.Believe that the zinc dialkyl dithiophosphate of methyl isobutyl carbinol type zinc dialkyl dithiophosphate that contains signal portion or part can benefit from the phosphorus volatility of reduction.In above-mentioned example, described methyl isobutyl carbinol type zinc dialkyl dithiophosphate constitutes 100% or basically 100% of employed zinc dialkyl dithiophosphate.In another example, described zinc dialkyl dithiophosphate comprises at least 90% methyl isobutyl carbinol type zinc dialkyl dithiophosphate.Described lubricant can comprise at least 80% further in the example at one, or further alternatively, at least 70% methyl isobutyl carbinol type zinc dialkyl dithiophosphate.Further, when seeking lower phosphorus volatility, believe that lubricant can have benefited from the methyl isobutyl carbinol type zinc dialkyl dithiophosphate in conjunction with at least 50%.The present invention is easy to carry out considerable variation in it is implemented.Therefore foregoing description is not intended restriction, and should not be considered to be restricted in special example mentioned above of the present invention.The scope of intention protection will be as the criterion with the defined technical scheme of claim.
To distortion and alternative all dropping in the claimed scope of claim that embodiment of the present invention is done, they are considered under equivalence principle is the part of technical solution of the present invention.
