Abstract
The invention provides a method for preparing oil-based polyol ester by virtue of gutter oil and using the oil-based polyol ester as basic lubricating oil so as to add treatment and utilization channels for gutter oil and realize the high-quality utilization of gutter oil. The method for preparing the oil-based polyol ester by two-step transesterification reaction comprises the following steps: sequentially adding biomass-based raw materials, methanol and a catalyst into a reaction flask, and performing transesterification reaction to obtain biomass-based methyl ester; sequentially adding the biomass-based methyl ester, polyol and a catalyst into the reaction flask, and performing transesterification reaction to obtain biomass-based polyol ester. The biomass-based raw material comprise gutter oil, acid cottonseed oil and vegetable oil foots/soap, and can be utilized in a high-quality manner, and the prepared biomass-based polyol ester can be used as a raw material of biomass-based lubricating oil.
Description
Technical field
The present invention relates to a kind of method that waste grease high-qualityization utilizes, especially one utilizes waste grease to prepare grease-based polyol ester, and it can be used as the method for lubricant base.
Background technology
Sewer oil belongs to the reject product of catering industry, and face is wide in a large number, does not have good utilization of waste material channel at present both at home and abroad, not only causes severe contamination to environment; Some illegal retailers, come into the market as edible oil again using the sewer oil of production, bring very major injury to the health of people.How realizing the disposal and utilization of sewer oil, play the use value of sewer oil to greatest extent, is current problem demanding prompt solution.
At present, the comprehensive utilization of China to sewer oil mainly contains four kinds of modes: one is into and produces biofuel, and this technique comes into operation China, the U.S., Britain, Japan etc. are multinational, technology maturation; Two is preparing washing articles for use, low price; Three is building coatings, and excellent performance can reduce energy expenditure; Four is to prepare the products such as impregnating material, softening agent, biological demulsifying agent.
Summary of the invention
The object of this invention is to provide one utilizes waste grease to prepare grease-based polyol ester, and used as the method for lubricating base oil, to increase the treatment and use channel of sewer oil, high-qualityization realizing sewer oil utilizes.
The present invention can be realized by following technical scheme:
1) vegetables oil or animal oil, methyl alcohol, catalyzer are joined in reaction flask successively;
2) temperature of reaction is risen to 70-100 DEG C, back flow reaction 2-12 h;
3) temperature of reaction is down to room temperature, obtains bio-based methyl esters and glycerine mixed solution;
4) the bio-based methyl esters obtained, polyvalent alcohol, catalyzer are joined in reaction flask successively;
5) keep pressure of the inside of a bottle to be 0.01MPa, temperature of reaction rises to 100-250 DEG C, underpressure distillation 6h;
6) temperature of reaction is down to room temperature, obtains bio-based polyhydric alcohol ester.
Waste grease involved in the present invention comprises sewer oil, acidifying Oleum Gossypii semen, vegetable oil residue/soap etc.
The beneficial effect that the present invention produces is: grease-based polyol ester technique prepared by the present invention is simple; high-qualityization that simultaneously can realize vegetable and animals oils utilizes; the bio-based polyhydric alcohol ester of preparation can as the starting material producing green bio base lubricant, can well protection of the environment.
The grease-based polyol ester that the present invention prepares comprises glycerol glycerate, tetramethylolmethane glycerate, trihydroxy methyl propane glycerate etc., and performance perameter is as shown in the table.

Embodiment
embodiment 1
The first step: sewer oil and methyl alcohol are joined in reactor with mass ratio 1:2, then the vitriol oil adding 2wt% makes catalyzer, react 6 hours under temperature is 80 DEG C of conditions, transesterify obtains thick product.By thick product separatory, deglycerizin, obtains unsaturated fatty acid methyl ester.
Second step: join in reactor by the above-mentioned unsaturated fatty acid methyl ester that is obtained by reacting and tetramethylolmethane with mass ratio 4:1, catalyzer made by the potassium hydroxide adding 2wt%, is 130 DEG C in temperature.Vacuum tightness is react 6 hours under the condition of 0.01MPa, removes unnecessary tetramethylolmethane, obtains unsaturated fatty acids pentaerythritol ester.
Claims (2)
1. a method for waste grease high-qualityization utilization, with sewer oil, acidifying Oleum Gossypii semen, vegetable oil residue/soap for raw material, prepare the method for grease-based polyol ester through two step ester exchange methods, it is characterized in that comprising the following steps:
1) esterification reaction of organic acid: by vegetables oil or animal oil and methyl alcohol, an acidic catalyst, at temperature is 70 ~ 100 DEG C, reacts 2 ~ 12 hours, obtain esterification product, the mass ratio of its Raw and methyl alcohol is 1:2 ~ 10;
2) transesterification reaction: by the esterification product that obtains in step 1) and polyvalent alcohol, basic catalyst, it is 100 ~ 250 DEG C in vacuum, temperature, react 1 ~ 10 hour, removing catalyzer and excess polyol, obtain bio-based polyhydric alcohol ester, wherein the mass ratio of esterification product and polyvalent alcohol is 1 ~ 6:1.
