Abstract
The invention relates to a preparation method of a lubricating composition characterized by non-high-polymer organic compound base materials, particularly a preparation method of poly-alpha-olefin (PAO) synthetic lubricating oil. The preparation method comprises the following steps: evenly mixing weighed anhydrous AlCl3 and cyclohexanone, slowly and dropwisely adding 20mL of 1-decylene while stirring, and keeping a certain reaction temperature with a thermostatic water bath; and after reacting for some time, washing the product with alkali, washing with water to a neutral state, standing for separation, and carrying out vacuum distillation. The product purity is high (up to 92%), and can be used for synthesizing low-viscosity and high-viscosity-index PAO. The chromatographic analysis result indicates that tripolymers and tetramers account for the maximum proportions in the synthesized PAO product, and the ideal component volume percent of the lubricating oil is higher than 85%.
Description
Technical field
The present invention relates to a kind of preparation method of the lubricating composition take the on-macromolecular organic compound base-material as feature.
Background technology
In recent years, linear alpha-alkene (LAO) is very fast for the synthesis of the production development of lubricant base, has caused the concern that people are general.Adopt two keys at the C of α position
8～C
12Alkene is C especially
10Poly-alpha olefins ucon oil (PAO) performance that alkene synthesizes is more excellent, is widely used in producing synthetic lubricant base oil.The advantages such as PAO has that liquid range is wide, viscosity-temperature characteristics can be good, pour point is low, viscosity index is high and vaporization losses is little, therefore in current many top-grade lubricating oil product, PAO is generally by preferably as the base oil of lubricating oil.The performance of PAO depends on that the polymerization degree of poly ﹠ Alpha ,-olefin oil and relative molecular mass distribute, and polymerizing catalyst is determinative.With A1C1
3The polymer yield that one complex compound prepares when being catalyzer is high, relative molecular mass narrowly distributing, selectivity are good.By a large amount of studies confirm that, A1C1
3Be better than A1C1 with catalytic activity after the material complexing that can separate out proton
3The carbonyl of pimelinketone protrudes from outside the ring, and is sterically hindered little, easily is combined with aluminum chloride, makes the electronic cloud deflection oxygen of Cheng Jian between the carbon oxygen, strengthens the positive polarity of carbonylic carbon atom, is conducive to the carrying out that react, and therefore, can select pimelinketone is that part strengthens A1C1
3Catalytic activity.
Summary of the invention
The present invention aims to provide the preparation method of the high poly-alpha olefins ucon oil of a kind of product purity.
The preparation method of poly-alpha olefins ucon oil of the present invention may further comprise the steps: with load weighted anhydrous A1C1
3Mix with pimelinketone, then slowly drip while stirring the 20mL 1-decene, with water bath with thermostatic control control and keep certain temperature of reaction, behind the reaction certain hour product is carried out alkali cleaning, be washed to neutral after standing separation, get final product through underpressure distillation again.
Preferably, pimelinketone and anhydrous A1C1
3Mol ratio be 0.5-0.7.
More preferably, pimelinketone and anhydrous A1C1
3Mol ratio be 0.5.
Perhaps preferably, anhydrous A1C1
