Description
Technical field
The present invention relates to a kind of wood vinegar, especially a kind of preparation method of wood vinegar.
Background technique
The yellowish-brown that wood vinegar is emerged when being by the burning of plant raw material of wood-charcoal is simultaneously formed after the cigarette recycling cooling with irritating pungent
Liquid.The property of wood vinegar is different and different with the type of raw material of wood-charcoal, the water content of raw material of wood-charcoal and its preparation method.Even identical charcoal
The wood vinegar of material, constituent species, content also can different from, with collection technology, the resting period, refining methd difference and
It is different.In recent years, occurs the wood vinegar of a variety of different raws material of wood-charcoal in the world, since wood vinegar is with the difference of raw material of wood-charcoal, physics and chemistry
Matter is also different, therefore, the preparation method for thering is the bigger market demand to remove to research and develop a kind of new wood vinegar in wood vinegar.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation method of wood vinegar, the product obtained with the method, indices
Better than similar product.
The present invention adopts the following technical scheme:
A kind of preparation method of wood vinegar carries out in accordance with the following steps:
1) timber carries out the smoke evacuation generated when charing production by retort or gas retort, directly receives after cooling, cohesion
The liquid of collection, obtains crude pyroligneous acid；
2) crude pyroligneous acid standing 6 months or more, its precipitating is allowed to be divided into three layers, top layer is light oil, and lowest level is solvable
Property wood tar, remove upper layer light oil after, take the liquid of middle layer, obtain aging wood vinegar；
3) aging wood vinegar is first given into filtering, is subsequently poured into the work of 3~4% charcoal powder or 2% that account for wood vinegar quality
Property charcoal, be sufficiently mixed, after placing one day, then give filtering, become acetum pyrolignosum rectificatum liquid；
4) acetum pyrolignosum rectificatum liquid is taken, is extracted every time with ether, is extracted 6 times, diethyl ether solution is merged, vacuum recycles ether,
Obtain wood vinegar concentrate.
By adopting the above technical scheme compared with prior art, the present invention indices be better than similar product.
The present invention adopts the following technical scheme:
In step 4), the proportion of wood vinegar and ether is 100~120g:30~40ml.
In step 4), the proportion of wood vinegar and ether is 100g:30~40ml.
Pour into 4% charcoal powder for accounting for wood vinegar quality.
Specific implementation formula mode
The present invention is described in detail below with reference to embodiment:

A kind of preparation method of wood vinegar carries out in accordance with the following steps:
1, apple tree is selected as timber and carries out the smoke evacuation generated when charing production by retort or gas retort, through cold
But, that directly collects after agglomerating arrives with sour liquid as main component, obtains crude pyroligneous acid.
2, crude pyroligneous acid standing 6 months or more, its precipitating is allowed to be divided into three layers, top layer is light oil, and lowest level is solvable
Property wood tar, remove upper layer light oil after, take the liquid of middle layer, obtain aging wood vinegar.
3, aging wood vinegar is first given into filtering, is subsequently poured into 4% charcoal powder for accounting for wood vinegar quality, the two is sufficiently mixed
It closes, after placing one day, then gives filtering, become acetum pyrolignosum rectificatum liquid.
4, acetum pyrolignosum rectificatum liquid 100g is taken, is extracted every time with 30ml ether, is extracted 6 times, diethyl ether solution is merged, vacuum is returned
Ether is received, wood vinegar concentrate is obtained；Wood vinegar and other substances are matched according to actual needs, can produce cosmetics,
The products such as the antibacterial disinfectant of deodorization, all indicators are better than similar products.
The physical and chemical index of product should meet the requirement of table 1.
