Description
The present invention relates to a kind of overbased preparation process lubricant oil additive, especially a kind of preparation method of ultrahigh-basicity composite metal detergent belongs to the lubricating oil field.
As everyone knows, lubricant oil metal detergent is mainly used in the engine oil, it can suppress the generation that oil ageing is gone bad or reduced the surperficial high temperature deposition thing of piston land (piston, piston ring, cylinder sleeve, annular groove) under hot conditions, make engine interior (combustion chamber and crankcase) keep peace and quiet.Metal detergent generally by carbonate (or borate) be adsorbed on the oil solution that stable load micelle that the lip-deep tensio-active agent of carbonate (or borate) forms and free surfactant molecule and micella thereof are constituted, it mainly comprises alkylbenzene sulfonate, alkyl monosulfide phenates, alkylsalicylate, sulfate-phosphate etc.Alkylsalicylate (calcium, magnesium) has obtained using widely as the used main additive of I. C. engine oil, wherein mainly comprises the calcium salt product of basic, normal, high base number.In recent years, along with save energy and more and more strictness of environmental protection requirement, engine design develops to miniaturization, high-power, high-speed direction day by day, and therefore the high temperature detergent performance to oil product has proposed more and more harsher requirement.Overbased metal detergent product also has good performances such as thermostability except that having fabulous high temperature detergent performance, will be widely used in the top-grade lubricating oil, especially in base number higher bunker oil and railroad engines oil.Owing to have high base number, thereby can reduce the add-on of additive in oil product significantly.It is more that relevant overbased sulfonate production prepares patent, but the patented technology of relevant ultrahigh basicity alkyl salicylate seldom is seen in report, only having at present with methyl alcohol is promotor, once metallized preparation technology is seen in report, but synthetic product under this technology is unsatisfactory with the consistency of sulfonate; In the patent No. is in the patent of CN94106385.2, though can see and when the preparation alkyl sodium salicylate, introduce tensio-active agent, solved the compatibility problem of two big class purification agents, but be a metallization process, and basicity alkyl calcium salicylate product in only obtaining can not satisfy the high alkalinity requirement of oil product.
The objective of the invention is to provide a kind of based on alkyl salicylate, under the condition of introducing secondary accelerator and tensio-active agent, prepare ultrahigh-basicity composite calcium salt metal detergent by the secondary metals metallization processes, this product not only contains a certain amount of alkylsalicylate, alkylbenzene sulfonate, but also contain a spot of alkyl phenate, thereby except that every performance with traditional ultrahigh basicity alkyl calcium salicylate, particularly the consistency with sulfonate has had very big improvement, thereby can be the new additive agent that lubricating oil provides a kind of compatibility performance, favorable dispersity.
The preparation method of a kind of ultrahigh-basicity composite metal detergent calcium salt of the present invention, promptly introduce tensio-active agent and two single metal metallization processes are as follows: the gasoline (industrial goods) and the methyl alcohol (industrial goods) that in there-necked flask, drop into metering, be warming up to 30-60 ℃, drop into the industrial calcium oxide (purity is more than 93%) of metering, the water that adds metering simultaneously, observe mixture retrogradation gradually in the flask, and be attended by the temperature rise phenomenon.Stir after 30 minutes, add the alkyl salicylate of metering and specific tensio-active agent alkyl benzene sulphonate (ABS), stirring reaction is kept temperature of reaction 40-60 ℃, carries out neutralization reaction 1 hour.Thereafter add metered calcium oxide, methyl alcohol and Ammonia secondary accelerator, under 40-60 ℃, keep reaction 30 minutes, feed a certain amount of carbon dioxide then, carry out high basicity reaction 2 hours.After reacting end, be warming up to 110 ℃, steaming engaging benzenemethanol and water dilute the decompression of centrifugal back and steam desolventizing, get product.Promotor is used methyl alcohol, and secondary accelerator uses ammonia and ammonium salt, and tensio-active agent is an alkyl benzene sulphonate (ABS), and the ratio of components of each component has certain ratio.In 90 parts of (weight) alkyl salicylates (about oil-containing 40%), tensio-active agent is 1-60 part, calcium oxide is 25-35 part, methyl alcohol is 30-150 part, water is 6.0-13.0 part, and the Ammonia secondary accelerator is 1.0-10.0 part, and solvent is 40-200 part, carbonic acid gas is 20-100 part, and temperature of reaction is controlled between 40-60 ℃.Tensio-active agent is two alkyl or monoalkylated benzenes sulfonic acid, and this reaction system can be fit to the calcium oxide of different stage, and reaction can be that boiling range is 60-160 ℃ a straight-run spirit with solvent, also can be that boiling point is higher than 120 ℃ material, as dimethylbenzene.The structure of reacting used main raw material alkyl salicylate is:
Wherein R is C
8-30Alkyl chain.Methyl alcohol must be purity greater than 95% chemical reagent or industrial goods, and secondary accelerator can be Ammonia products such as ammoniacal liquor, volatile salt or bicarbonate of ammonia, preferably selects chemical pure bicarbonate of ammonia for use.Tensio-active agent, methyl alcohol, the water yield and secondary accelerator are the principal elements that influences product base number and viscosity.The appropriate surfactant consumption is 2.0-50.0 gram/90 gram alkyl salicylates, and methanol usage is 60-150 gram/90 gram alkyl salicylates; The consumption of suitable water is 7.0-12.0 gram/90.0 gram alkyl salicylates.Sintetics has excellent anti-oxidant anticorrosive, thermally-stabilised, consistency and detergent-dispersant performance energy.
In the synthetic reaction process of ultrahigh-basicity composite metal detergent calcium salt product of the present invention:
The effect of methyl alcohol: methyl alcohol is as the carrier of inorganic phase and organic phase, can make in the reaction mixture gas, liquid, solid three-state and oil solution and aqueous solution two-phase evenly mixed, simultaneously, methyl alcohol has the surface energy that reduces calcium oxide, wetted surface promotes that slaking reaction can slowly and reposefully carry out.At last, methyl alcohol also can promote the formation of colloidal particle as carrier.
The effect of water in reaction: water is a kind of reaction reagent, slaking reaction needs just to carry out having under the condition of water, and only under the condition that guarantees the water yield, just may make the calcium hydroxide homodisperse of generation, the original place generates the less lime carbonate lattice of particle diameter, and participating in into the glue reaction, the synthetic product viscosity is also less like this.
The effect of secondary accelerator: the introducing of secondary accelerator, can improve the reactive behavior of methyl alcohol, impel the calcium hydroxide homodisperse of generation, the original place generates the less lime carbonate lattice of particle diameter, guarantees that reaction process is steady, and participates in into the glue reaction.
The effect of tensio-active agent: the present invention makes reaction medium that great variety take place owing to having introduced the tensio-active agent alkyl benzene sulphonate (ABS), alkyl benzene sulphonate (ABS) is as a kind of reaction reagent, it can stop the calcium carbonate granule of generation and alkyl sodium salicylate micella to assemble growth, and impel it rapidly to generate load micelle and stably be scattered in the oil solution, simultaneously, alkyl benzene sulphonate (ABS) can generate the mixed micelle that particle diameter is more evenly distributed more for a short time with alkyl salicylate, and participates in into the glue reaction.Investigation result to tensio-active agent is as follows:
