A Method for Refining Wood Vinegar and Refined Wood Vinegar Thereby

摘要

The present invention relates to a method for purifying crude wood vinegar using a catalyst and thus purified high-purity wood vinegar. The crude wood liquor and hydrogen peroxide were oxidized in the presence of catalyst phosphoric acid at about 30 ~ 70 ℃ for about 8 ~ 12 hours, then left for about 36 ~ 40 hours, and after removing the aggregates formed at about 3.5 ℃ at about 90 ~ 120 ℃ A method of purifying wood vinegar distilled for ˜4.5 hours and thus purified wood vinegar is provided. According to the method of the present invention, the carbonized suspension and the coal in the crude wood vinegar are removed in a short time and with high efficiency. The wood vinegar purified by the method of the present invention is excellent in bactericidal activity, does not contain harmful substances, odors are removed, and can be applied in various methods and fields.;Crude wood liquor, wood vinegar, phosphoric acid, hydrogen peroxide, acetic acid, peracetic acid, methanol, formic acid
