Problems solved by technology

It can be used as a soil improver and plant growth regulator in agriculture, but due to the complex composition, the quality of the product is unstable, and it is easy to appear turbidity and stratification during use, which directly affects the application of the product
At present, the purification technology of bamboo vinegar stock solution mainly includes simple standing and rectification. Among them, standing still takes a long time, usually more than half a year, and the quality of the obtained product is still not very stable.
However, the cost of rectification is high, and the residue of rectification takes away a lot of active ingredients, which reduces the use effect of the product

Embodiment 1

[0011] Take 900g of the stock solution of bamboo vinegar, add 40g of Nongru 500#, 30g of Nongru 700# and 30g of polysorbate-80 under stirring at room temperature, and continue stirring for 30 min.

[0012] Observing the stability of the obtained product at 0°C to 45°C, it is found that the product obtained by this method can remain stable at 0°C to 45°C without delamination and turbidity.

Embodiment 2

[0014] Take 1000g of bamboo vinegar stock solution, add 40g of Nongru 500#, 35g of Nongru 700# and 35g of polysorbate-80 under stirring at room temperature, and continue stirring for 50 min.

[0015] Observing the stability of the obtained product at 0°C to 45°C, it is found that the product obtained by this method can remain stable at 0°C to 45°C without delamination and turbidity.

Embodiment 3

[0017] Take 1000g of bamboo vinegar stock solution, add 50g of Nongru 500#, 30g of Nongru 700# and 40g of polysorbate-80 under normal temperature stirring, and continue to stir for 1 hour.

[0018] Observing the stability of the obtained product at 0°C to 45°C, it is found that the product obtained by this method can remain stable at 0°C to 45°C without delamination and turbidity.

Abstract

The invention discloses a purification method of a bamboo vinegar stock solution. The method comprises the following steps: taking the bamboo vinegar stock solution, adding emulsifiers calcium dodecylbenzene sulfonate, alkyl phenol formaldehyde resin polyethenoxy ether and polysorbate-80 while stirring, and continuing stirring for 0.1-2 hours. The calcium dodecylbenzene sulfonate, alkyl phenol formaldehyde resin polyethenoxy ether and polysorbate-80 respectively account for 3-5 wt%, 2.5-4 wt% and 2.5-4 wt% of the bamboo vinegar stock solution. The method has the advantages of simple production technique, controllable conditions and low treatment cost. The obtained product is very stable at 0-45 DEG C, and does not have the phenomenon of stratification or turbidity.

Description

technical field [0001] The invention relates to a method for purifying the stock solution of bamboo vinegar liquid. Background technique [0002] Bamboo vinegar stock solution is a liquid substance obtained by collecting the gas produced in the pyrolysis of bamboo during charcoal burning with bamboo, and cooling the gas at normal temperature. Bamboo vinegar contains nearly 300 kinds of natural macromolecular organic compounds, such as organic acids, alcohols, ketones, aldehydes, esters and trace amounts of alkaline components. It can be used as a soil improver and plant growth regulator in agriculture, but due to the complex composition, the quality of the product is unstable, and it is prone to turbidity and stratification during use, which directly affects the application of the product. At present, the purification technology of bamboo vinegar liquid stock solution mainly contains two kinds of simple standing and rectification. The time spent standing still is long, gene...
