The invention relates to an alcohol ester type green lubricating oil manufacturing method. It improves vegetable oil oxidation stability by chemical modification. It belongs to lubrication oil modification technique field. It adopts vegetable oil to do chemical medication, such as bean oil, castor oil, cotton oil, and so on. It uses H202 to change double bond into saturated epoxy bond, and open oxidation bond to form isomery ester by esterifying method. It processed lubricating oil has better anti-oxygen performance, viscosity, abrasion resistant, and viscosity-temperature characteristics.
Description
Technical field
The present invention relates to a kind of preparation method of lubricating oil of alcohol ester type environment, specifically a kind of vegetables oil is improved the method that oxidative stability is made the lubricating oil of alcohol ester type environment by chemical modification.Belong to modifying lubricating oil Technology field.
Background technology
Vegetables oil can be used as lubricant.Vegetables oil is a photosynthate, is reproducible and biodegradable.But, can only be used in the lubricated of the not high old-fashioned machinery of temperature because the plant oil oxidation stability is poor.Soya-bean oil, rape oil, peanut oil or castor-oil plant wet goods vegetables oil be oxidation easily under condition of storage, isolates free acid, can etching mechanism part metal parts.In addition, also can polymerization under the atmospheric oxidation condition form paint film, as stick to machinery part surface and will destroy lubrication.
Modern machinery and equipment to the requirement of lubricating oil is: (1) is environmentally friendly, and is nontoxic, biodegradable; (2) higher oxidation-resistance is arranged, arranged long work-ing life; (3) require that pour point is low, viscosity index is high, can adapt to the special occasions of severe cold and high temperature operating mode; (4) be convenient to the oil product of synthetic different viscosity grade.
Vegetables oil is carried out chemical modification, can produce a kind ofly have good in oxidation resistance, high low temperature adaptability is good, biodegradable high-quality ucon oil.
Summary of the invention
The objective of the invention is by chemical modification, to improve oxidative stability and a kind of method of making alcohol ester type environment lubricating oil is provided vegetables oil.
The preparation method of the lubricating oil of a kind of alcohol ester type environment of the present invention is characterized in that having following preparation process and step:
A. be raw material with vegetables oil (as soya-bean oil, peanut oil, rapeseed oil, castor-oil plant wet goods), it is carried out chemical modification; Taking by weighing a certain amount of vegetables oil is put in the there-necked flask, bottleneck one end inserts the separating funnel that a certain amount of Glacial acetic acid, hydrogen peroxide (hydrogen peroxide) and the vitriol oil are housed, vegetables oil and Glacial acetic acid are with 1: 1～3 mixed in molar ratio, be preheated to 40 ℃, drip Glacial acetic acid, hydrogen peroxide and vitriol oil mixed solution while stirring, maintain the temperature between 40～60 ℃, in 1 hour, dropwise, keep temperature in 50～60 ℃ subsequently, under this temperature, continue reaction 3 hours; Reaction mass is poured out, placed separating funnel to leave standstill, wash thick product to PH=5 with 0.5～1.0% sig water then, treat after the layering water to be emitted, oil phase is refunded in the there-necked flask;
B. in the above-mentioned there-necked flask that fills oil phase, add a certain amount of Glacial acetic acid or aceticanhydride, band water solvent benzene, toluene or gasoline (as just can not adding with aceticanhydride) again, oil phase and Glacial acetic acid or aceticanhydride are with 1: 2～6 mixed in molar ratio; Stirring also refluxes, and Heating temperature is 70-80 ℃, and the reaction times is 9～10 hours, sloughs reaction water; When question response water stops to carry outside, can think to react and reach home that behind the stopped reaction reactant carried out alkali cleaning, be washed to neutrality, vacuum hydro-extraction more finally obtains alcohol ester type lubricating oil.
The ultimate principle of the chemical modification of the inventive method is as follows:
(1) because there is double bond structure in vegetables oil, so its oxidative stability is relatively poor; At first adopt oxydol H in present method the first step
2O
2, two keys are changed over saturated epoxy bond.(2) and then adopt esterification process unsettled oxidation key to be opened the dibasic acid esters that generates the isomery shape.
Through the upgrading vegetables oil after epoxidation and the isomery esterification treatment, its antioxygen improves greatly, and its viscosity also has greatly improved.
The alcohol ester type compound that makes after plant oil modified includes following four kinds of structures:
The advantage of the alcohol ester type lubricating oil of the inventive method gained is:
(1) environmentally friendly, nontoxic, biodegradable.
(2) higher oxidation-resistance is arranged, arranged long work-ing life.
(3) can obtain the viscosity height, viscosity temperature characteristic is good, viscosity index VI height, the ester type synthetic oil that pour point is low.
(4) can be mixed into the oil plant of various viscosity grades with low viscous ester type oil, make low, in or the oil product of high different grades.
Embodiment
After now embodiments of the invention being described in.
Embodiment 1
Take by weighing a certain amount of soybean oil and place there-necked flask, bottleneck one end inserts the separating funnel that a certain amount of Glacial acetic acid, hydrogen peroxide and the vitriol oil are housed; Soybean oil and Glacial acetic acid are preheated to 40 ℃ with 1: 2 mixed in molar ratio, drip Glacial acetic acid, hydrogen peroxide and the vitriol oil while stirring, maintain the temperature at 50 ℃, dropwise in 1 hour, keep temperature in 60 ℃ subsequently, continue reaction 3 hours under this temperature; Reaction mass is poured out, placed separating funnel to leave standstill, wash thick product to PH=7 with 1.0% sig water then, treat after the layering water to be emitted, oil phase is refunded in the there-necked flask.In filling the there-necked flask of oil phase, add a certain amount of Glacial acetic acid, band aqua toluene then again; Oil phase and Glacial acetic acid were with 1: 4 mixed in molar ratio; Heated and stirred also refluxes; Heating temperature is 70-80 ℃, and the reaction times is 9 hours, sloughs reaction water; When question response water stops to carry outside, can think to react and reach home stopped reaction; Reactant is carried out alkali cleaning, is washed to neutrality, and vacuum hydro-extraction more finally obtains alcohol ester type lubricating oil.As with aceticanhydride reaction, just can be without water liquid benzene, with vegetables oil with 1: 2 molar ratio reaction, to make alcohol ester type lubricating oil with sampling technology.
The rheological of table 1 alcohol ester type lubricating oil of the present invention and soybean oil and friction and abrasion contrast
Show that according to test data in the last table alcohol ester type lubricating oil of the present invention is compared with soya-bean oil, has following advantage:
(1) frictional behaviour is more excellent; Use the tetra-ball machine test long term wear, wear scar diameter is as index, and modified soyabean oil is that alcohol ester type lubricating oil is 0.30mm, and soya-bean oil is 0.43mm, and modified soyabean oil is significantly smaller than raw material soya-bean oil; Its P
bValue is much higher than soya-bean oil 637N for 862N.
(2) rheologic behavio(u)r is better; Modified soyabean oil viscosity is up to 1469mm
2/ s (with it is base oil, composite with the low viscosity oil plant, can modulate the lube stock of a series of viscosity grades); Pour point descends to some extent than raw material soya-bean oil, is-15 ℃.
Find that after tested modified soyabean oil allotment oil oxidation stability has had raising by a relatively large margin, is much better than vegetables oil.As prepare with modified soyabean oil and diisooctyl sebacate viscosity grade be the level oil of striding of No. 32 oil, behind composite antioxidant, its rotary oxygen bomb oxidation induction period (140 ℃) is 1702 minutes, and the rotary oxygen bomb oxidation induction period of former soya-bean oil (140 ℃) is 249 minutes.
Modified soyabean oil is that 21 all kinds of things in nature degradation rates of alcohol ester type lubricating oil are 97% after tested, meets German blue angels standard, so be environmental friendly lubricant.
