Abstract
The present invention relates to environment protection and vegetable oil extracting technology, and is especially the process of esterifying vegetable oil in a microwave synthesizer to produce fatty alcohol amine ester used as lubricant. The microwave synthesis process is performed at normal temperature and normal pressure, uses no catalyst, produces no pollutant and has conversion rate as high as 95.5 %.
Description
Technical field
The present invention relates to environment protection, vegetables oil refinement technique field, refer in particular to a kind of vegetables oil that utilizes and in microwave synthesizer, carry out the method for esterification reaction production lipid acid hydramine fat as lubricant.
Background technology
Modern mechanical processing at a high speed, powerful, accurate direction develops, the development of difficult-to-machine materials such as superhard, super-strength also makes the difficulty of machining increase day by day.The reason of this two aspect causes frictional force, the heat of friction in the cutting process to increase substantially, and this just requires metal working fluid to have better lubricated, cooling, cleaning, rustless property, so that obtain the ideal finished surface.Mineral lubricating oils lubricated, rustless property is superior, but cooling, cleaning performance are poor; Cooling, the cleaning performance of emulsion and water-base cutting fluid are good, but lubricated, rustless property is poor.Water-base cutting fluid is except that all properties with emulsion, and it is lubricated, cooling, rustless property also reached and surpass outside all properties of emulsion, the standard-required that it is lubricated, cooling, rustless property also meet or exceed emulsion.Thereby water-base cutting fluid has become the developing direction that improves processing characteristics in the domestic and international mechanical workout.The present water-base cutting fluid that adopts, mainly be to adopt chemical synthesis, produce band hydrophilic radical hydrocarbon alkane thing, the lubricant of water is dissolved in formation, but the production one of this compounds is that material cost is higher, the 2nd, need conditions such as catalyzer, temperature, pressure and rare gas element in the chemical combination process, cause that cost is excessive, contaminate environment, the low inferior major defect of yield rate.
Summary of the invention
Purpose of the present invention is exactly to propose a kind of by the method for vegetable oil production lipid acid hydramine fat as lubricant at above-mentioned situation.
For achieving the above object, the present invention is reactant, adds oleic acid as conditioning agent with vegetables oil and hydramine, carries out esterification reaction in microwave synthesizer, i.e. lipid acid hydramine fat; Hydramine mole number wherein: the vegetables oil average mol is 0.3-4.5: 1, the oleic acid of 1-3.9 part carries out the raw materials of compound formulation ratio as conditioning agent by weight, through sent out in 1-30 minute should after, promptly obtain the pure amine fat of lipid acid, separate desired product and purifying subsequently, its production process and processing condition are:
A) above-mentioned formulation ratio is finished after, the stirrer that utilizes rotating speed 300-3200 rev/min was with raw material stirring 15-90 minute;
B) stirring the raw material finish enters and reacted at normal temperatures and pressures in the 600W-1800W microwave synthesizer 1-30 minute;
C) react the goods of finishing and be cooled to room temperature;
D) deionized water of the 50%-500% of product weight stirs at a slow speed and adds above-mentioned finished product, and add the defoamer of 0.3-5%, the oxidation inhibitor of 0.1-10% stirs more than 15 minutes, separate the milky white color fat in upper strata and separate as lubricating grease, all the other are the finished product.
Do not need any catalyzer in the reaction process.
Described vegetables oil is one or more the mixture in rapeseed oil, Semen Maydis oil, peanut oil, sweet oil, Thistle oil, soybean oil, Trisun Oil R 80, plam oil, the tip water oil.
Described hydramine is to have list, two, three and the hydramine of many thanomins functional group.
Adopt of the present invention method, directly adopt vegetables oil as raw material, building-up process is used microwave method, carries out under the normal temperature and pressure atmospheric condition, does not use catalyzer, does not produce pollutent, and finished product transformation efficiency high energy arrives 95.5%.Overcome in the existing chemical combination process need that catalyzer, cost are big, contaminate environment, defective that yield rate is low.Because the plant main body of oil is fatty acid ester (comprising saturated and unsaturated composition).The molecular formula of fatty acid ester can be expressed as follows:
R wherein
1, R
2, R
3Be identical or different fatty acid chains.In vegetables oil, saturated fatty acid contains 22 carbon atoms, the carbon atom number from 10 to 22 of single unsaturated link(age) lipid acid, and two carbon atom numbers unsaturated and three unsaturated fatty acidss are generally 18.Bandit's acid and different linolic acid and linolenic acid etc. of in vegetable fatty acids, containing lauric acid, the 0.3-0.7% of 0.1-0.8%.Method of the present invention is utilized lipid acid (mainly being unsaturated fatty acids) and hydramine esterification reaction, forms water miscible group on the lipid acid segment; Utilize lauric acid, bandit acid and hydramine reaction to produce nonionogenic tenside, thereby very easily finish water-solubleization of vegetables oil, and reduced the second-order transition temperature of lipid acid, make the new system of formation satisfy functional requirements such as lubricated, cooling, anti-embroidery.
1) product lubricity of the present invention is good: in metal cutting processing, the great majority friction belongs to the boundary lubrication friction.In boundary lubrication, owing to there is not oil film completely, its supporting capacity is irrelevant with oil viscosity, and depends on the oiliness of lubricating fluid, and whether promptly lubricated composition is comprising the atomic group that metal is existed strong adsorption, can form the physical adsorption film at the cutting interface.In the present invention was synthetic, lauric acid, bandit's acid etc. formed nonionogenic tenside, and the polar group in its nonionogenic tenside has bigger affinity ability to metal, were easy to be adsorbed on the metallic surface, formed adsorbed lubricating film.Because of its hydrophobic grouping is bigger, has the effect of oiliness improver.Can prevent or reduce the direct contact between workpiece, cutting, the cutter, reach reduce the friction and the agglutinating purpose, play fabulous lubrication.
The lipid acid hydramine is a kind of cats product, is added in the cutting fluid as oiliness improver, easily forms the physical adsorption film between sword and cutting workpiece, thus the lubrication of playing.In addition, fatty acid ethanolamide amine and extreme pressure anti-wear additives also have good collaborative wear-resistant effect, and lubricity is significantly improved.
2) cleaning performance is good: the quality of cutting fluid cleaning performance, be closely related with cutting fluid penetration and flowability, and surface tension is low, the cutting fluid of perviousness and good fluidity, and cleaning performance is all right.
In the novel water-based cutting fluid because the existence of not low nonionogenic tenside of content and cats product lipid acid hydramine is arranged, the two coordinative role, greatly reduce the surface tension of cutting fluid, strengthened the perviousness and the flowability of cutting fluid significantly.Thereby has a good cleaning performance.
3) cooling performance is good: the cooling effect of cutting fluid, depend on its thermal conductivity, specific heat, vaporization heat and vaporization rate etc.The thermal conductivity of water is 3～5 times of oil, and specific heat is 2～2.5 times of oil, and the cooling performance of Gu Shui is superior more a lot of than oil.Contain the moisture more than 90% in the novel water-based cutting fluid, so cooling performance is outstanding.
4) good antirust property: nonionogenic tenside itself has anti-the embroidery and preservative activity; produce the composite synergistic effect with the lipid acid hydramine; form the absorption protective film in the metallic surface; passivation film; thereby blocked the cathode and anode corrosion process; because fine and close mulch film is arranged, and the infiltration that can resist water molecules, oxygen and other corrosivess in the medium effectively has good anticorrosion, rustless property.
