Description

A kind of preparation method of palm oil-base Biodegradable lubricant

Technical field

The present invention relates to a kind of preparation method of palm oil-base Biodegradable lubricant.

Background technology

The conventional lubricant overwhelming majority is mineral based lubricants, and it has played very your writing in past industrial and agricultural production With, but mineral oil is difficult to biodegradation, is flowed into environment and necessarily environment is caused seriously to pollute；In recent years, as people are to ring The pay attention to day by day of border problem, the research about biodegradable lubricants are more and more；Vegetable oil due to have good lubricity, The features such as biodegradable, wide, renewable viscosity-temperature characteristics and source, turn into a kind of Biodegradable lubricant of most competitiveness Base oil；But the oxidation stability of vegetable oil is poor, in vegetable oil in addition to making it containing C=C double bonds and easily being aoxidized, its glycerine Mouth-H in molecule is tertiary hydrogen, also causes it that pyrolysis and elimination reaction easily occurs, causes service life not grow；Therefore The glycerine in the polyalcohol substituted plant oil molecule without her H can be used, synthesizes the preferable ester lubricant of combination property, three hydroxyls Methylpropane fatty acid ester is by a kind of modified product；Ester exchange method is prepared for trihydroxymethylpropanyl ester respectively, production Product have good cryogenic property, antioxygenic property, rub resistance, wear-resistant, and this synthetic ester lubricant has preferably life Thing degradability, it is a kind of Biodegradable lubricant of good performance.

At present, it is more that the research of lubricant is prepared with soybean oil, rapeseed oil etc., and the research of lubricant is prepared with palm oil It is less；With other plant oil phase ratio, palm oil yield is big, and cost is low, has higher economy and practical value.

The content of the invention

The present invention proposes a kind of alternative ore oil lubricant, the small biodegradable lubrication of palm oil-base of the pollution to environment The preparation method of agent.

The preparation method of a kind of palm oil-base Biodegradable lubricant of the present invention, it is characterised in that including following system Standby step：

（1）Take following raw material for standby：Palm oil, Tianjin Longwei Grain ＆ Oil Industrial Co., Ltd. provide, 0.16 milliliter every gram of acid number, soap 195 milligrams of change value, 1.169 moles every gram of peroxide value, every 100 grams of 66.11 milliliters of iodine number；Main fatty acid forms, oleic acid 47%, palmitic acid 33%, linoleic acid 13%, stearic acid 4%, myristic acid 0.9%；Seven sour methyl esters, German Di Ma companies；(polyisobutene), South Korea；T803B (poly- Q alkene), department's benzene 80, the safe lube oil additive Co., Ltd in Jiangyin；BHT, the auspicious general biochemistry in Shandong are limited Company；Withered grass bacterium, golden yellow coccus, aspergillus flavus, mould, Mucor, yeast, bread mold, aspergillus niger, He'nan University of Technology's bioengineering Institute provides；Escherichia coli, Agricultural University Of He'nan's Life Science College provide；Viscosity standard oil, Sinopec lubricant corporation There is provided；Engine recommendation oil, Shanghai General Motor Wuling Automobile Co., Ltd. provide；Hypoid gear oil, system in Beijing Jing are plump Lubricating oil Co., Ltd provides；Trimethylolpropane, CHlOH, CHl0Na, NaoH etc. are domestic AR；

（2）The amount ratio of palm oil and methanol material is 6:1, catalyst (NaOH) addition is gross mass 1% at 250 milliliters In three-necked flask, 150g palm oils are added, after being preheated to 55 DEG C, add NaOH methanol solutions, temperature control is at 55 DEG C, reaction 50min.Anti- fiber crops terminate rear stratification, separate lower floor's glycerine, and upper liquid is first neutralized with dilute HCl solution, then is washed with distillation To neutrality, then it is evaporated under reduced pressure, steams methyl esters；

（3）30g palm oil fatty acid methyl esters is weighed, is preheated to after 60 DEG C, by the amount of material than adding a certain amount of three hydroxyls first Base propane, after being warming up to reaction temperature at reduced pressure conditions, catalyst (CH30Na) is rapidly added in proportion, in certain temperature, React certain time, reaction weighs a certain amount of base oil and additive in proportion after terminating, and is separately heated to 55 DEG C, gradually adds Enter additive and often add a kind of additive, after must being allowed to be stirred well to base oil and mixing completely, add other additions Produced after agent.

Palm oil-base Biodegradable lubricant prepared by the inventive method, agent are poor except cryogenic property and oxidation resistance Outside, there is good viscosity-temperature characteristics and can pacify umbrella stability, nontoxic and easily biological-degradable, is a kind of biodegradable lubricant.
