Description
Technical field
The present invention relates to a kind of preparation method of lube base oil.
Background technology
Biological degradability is good, recyclability is strong, nontoxic, greasy property because it has for crude vegetal or vegetable oil base oil fat
The advantages that excellent, just increasingly by enter concern and attention, have become instead of oil product Green Lubricants basis
Oily raw material.Although crude vegetal has advantage inherently, but it also has the defects of many such as oxidizable, hydrolysis surely
Qualitative difference and poor performance at low temperatures etc..The presence of these weak points governs it and widely applied, generally use chemical modification
Method improve its performance.Conventional method of modifying has esterification, epoxidation and isomerization etc..But the lubrication after epoxidation
The raisings such as the performance such as cryogenic property of oil are not apparent.Contain a large amount of active epoxy second in epoxidized vegetable oil molecular structure
Groups, these groups are easy to that ring-opening reaction occurs with Organic Alcohol, organic acid.Open loop both at home and abroad on epoxidized vegetable oil is anti-
There should be many play-by-play, using the concentrated sulfuric acid as catalyst, the organic acid of epoxidized soybean oil and different chain length enters such as Li Qinghua
Row ring-opening reaction synthesizes a series of products and improves oxidation stability and rheologic behavio(u)r；Salimon etc. using p-methyl benzenesulfonic acid as
Catalyst, the sour and different organic acid of epoxy castor oil carry out isomerization reaction, and the oxidation stability of the open-loop products of synthesis obtains
Improve to good.The performance for substantially surrounding open-loop products that document is reported, and on the process conditions of isomerization reaction
Seldom it is related to, and raw materials used is epoxidized vegetable oil.Biodiesel is the substitute of petrifaction diesel, and main component is fatty acid methyl
Ester, this just provides good raw material for synthetic environment close friend's lube base oil.
The content of the invention
The present invention proposes a kind of preparation method of lube base oil.
A kind of preparation method of lube base oil is invented, it includes following preparation process：

Sour sodium etc. (analyzes pure, Chemical Reagent Co., Ltd., Sinopharm Group)；D001 resins, 7328 resins (open the limited public affairs of flat resin in Shanghai
Department)；
（2）200g rapeseed methylesters are added in the four-hole boiling flask with condenser pipe and thermometer and 16g formic acid, bottleneck one end are inserted
Enter the constant pressure separatory funnel of 90g hydrogenperoxide steam generators is housed, four-hole boiling flask is placed in thermostat water bath and is preheated to 40 DEG C；While stir
Mix side and hydrogenperoxide steam generator is added dropwise, maintain the temperature at 40~60 DEG C, 1h is added dropwise, and keeping temperature continues anti-in 60~65 DEG C
Answer 6h；
（3）After reaction terminates, reaction mass is poured into liquid separation is stood in separatory funnel, isolate lower floor's aqueous phase；
（4）Upper oil phase is washed to neutrality with distilled water, sodium carbonate liquor successively, is finally evaporated under reduced pressure, obtains epoxy vegetable seed
Oily methyl esters；
（5）A certain amount of epoxy rapeseed oil methyl esters, ethanol and catalysis are added in the four-hole boiling flask with condenser pipe and thermometer
Agent, certain temperature is heated to while stirring, and isothermal reaction for a period of time, after reaching 30 minutes, will react at such a temperature
Material is poured into separatory funnel, and reaction product is first washed to neutrality with 1.5%NaOH solution, then cleans sodium ion with distilled water, most
It is evaporated under reduced pressure afterwards and removes moisture and excessive ethanol, it is lube base oil to obtain final open-loop products.
Preferably, the temperature that hydrogenperoxide steam generator is added dropwise is 40 DEG C, and 1h is added dropwise, and keeping temperature is in 60 DEG C.
Preferably, the temperature that hydrogenperoxide steam generator is added dropwise is 60 DEG C, and 1h is added dropwise, and keeping temperature is in 65 DEG C.
The viscosity of the etherification modified epoxy methyl ester product of lube base oil ethanol prepared by the method for the invention is big, flash-point
Height, oxidation stability is preferable, has more preferably friction resistant performance.
