Description
Technical field
The present invention relates to field of biodiesel oil, be specifically related to the production method of branched biodiesel.
Background technology
Economical quickly increases the energy shortage brought make countries in the world accelerate find remove the traditional energy such as oil and coal with
The speed of outer new forms of energy.Biodiesel because of its have renewable, environmental protection, can mix with petrifaction diesel arbitrary proportion etc. excellent
Point and the attention of extremely government, educational circles and enterprise.Owing to its composition is polyunsaturated fatty acid ester and with one or more double
The unsaturated fatty acid ester of key, therefore has the features such as oxidizable and low temperature flow difference, which also limits biodiesel low
Such as the use of space flight, the arctic etc. in temperature environment.Little molecule aldehyde, ketone, acid and the macromolecule polyalcohol meeting that biodiesel oxidation generates
Cause electromotor can not to run well or damage.Low temperature flow difference can cause petroleum pipeline and plugged filter, makes oil pumping system
It is not normally functioning with electromotor, causes inconvenience also to the storage of biodiesel and transport.So research and development effectively, can
Development and the application of biodiesel will be had important by biodiesel oxidation stability and the low temperature flow improving technology of row
Meaning.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that the branched biodiesel can also being advantageously used under a kind of low temperature
Production method.
The technical solution adopted in the present invention is:
The production method of branched biodiesel, including procedure below:
Biodiesel being mixed with formic acid, agitating heating 40～60 DEG C, dropping catalyst and hydrogen peroxide mixed liquor, during reaction
Between 5h, reaction terminate after carry out separatory, take supernatant liquid add be washed to neutrality, obtain epoxidation biodiesel；Biodiesel
Being 1: 0.1: 1 with formic acid, hydrogen peroxide mass ratio, catalytic amount is the 2% of biodiesel fuel quality；
Epoxidation biodiesel mixes with fatty alcohol, agitating heating 40～60 DEG C, adds strong phosphoric acid, stirring reaction, reaction
Time 10h, separates ester layer after adding the potassium carbonate washing of 5%, i.e. obtains branched biodiesel after steaming low boiling component；Epoxy
Changing biodiesel and fatty alcohol mass ratio is 1: 5, strong phosphoric acid amount is the 1% of epoxidation biodiesel quality.
The production method of the branched biodiesel that the present invention provides, improves biodiesel oxidation stability and low temperature flow
Property, process equipment is less demanding, simple to operate, reaction condition is gentle.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated, but the present invention is not limited only to these embodiments, not
On the premise of departing from present inventive concept, within any improvement made all falls within protection scope of the present invention.
The production method of branched biodiesel, including procedure below:
Biodiesel being mixed with formic acid, agitating heating 40～60 DEG C, dropping catalyst and hydrogen peroxide mixed liquor, during reaction
Between 5h, reaction terminate after carry out separatory, take supernatant liquid add be washed to neutrality, obtain epoxidation biodiesel；Biodiesel
Being 1: 0.1: 1 with formic acid, hydrogen peroxide mass ratio, catalytic amount is the 2% of biodiesel fuel quality；
Epoxidation biodiesel mixes with fatty alcohol, agitating heating 40～60 DEG C, adds strong phosphoric acid, stirring reaction, reaction
Time 10h, separates ester layer after adding the potassium carbonate washing of 5%, i.e. obtains branched biodiesel after steaming low boiling component；Epoxy
Changing biodiesel and fatty alcohol mass ratio is 1: 5, strong phosphoric acid amount is the 1% of epoxidation biodiesel quality.
