Pyroligneous Acid or Wood Vinegar

Production of Wood Vinegar (pyroligneous acid) - Woodvinegar.org

Organic biomass material is heated in an oxygen reduced environment leading to the thermal decomposition of materials and release of gases (called pyrolysis) – this exhaust smoke is condensed (cooled) into a liquid. The condensate then further separates and refined into Tar, Wood Vinegar and Bio-Oil.
Production equipment can vary from basic metal drums or in ground fire pits covered in clay mud with cooled bamboo chimneys to state of the art industrial processors that are completely controlled continuous biomass converters.

When wood is subjected to destructive distillation or is greatly heated in close vessels, an acid liquor oozes over with the tar and gaseous products. This acid liquor is the pyroligneous acid. It is really an impure vinegar, from which acetic acid can be obtained, and the method employed is as follows: The pyroligneous acid freed from the tar, naptha, &c., is saturated w'th chalk or powdered slacked lime, filtered, and evaporated in suitable vessels. By this means an impure acetate of lime is obtained. This is gently heated to destroy the oily matter without injuring the acid, and then mixed with sulphate of soda or salt cake as the manufacturers call it ; this affords a beautiful acetate of soda, in solution, which is then drawn off from the remaining sulphate of lime. The solution is heated, evaporated to dryness, re-dissolved and crystallized, and by these means the acetate of soda is procured in crystals. These crystals are then placed in a retort with oil of vitriol and heated, when acetic acid distils over, which being the active principle of vinegar, this useful acidifier can easily be made from it, and of the very best quality. The charcoal which remains in the retort in which the wood is distilled is excellent, and is lal'gely used for the manufacture of gunpowder.

Wood vinegar application in the agricultural sector in Japan has been doing it for years, whether it is wood vinegar wood vinegar or foliar fungicides, have a good market demand, but also in Japan for agricultural use of pesticides and fertilizers is very strict control Therefore, post-processing of wood vinegar made by pesticides, not only can kill harmful bacteria and pests, but also natural degradation, becoming plant fertilizer, wood vinegar foliar effect is very obvious, obvious effect on crop yield.

There is evidence of use dating back thousands of years to the Amazon basin black terra preta earth – - in the 1800 and 1900’s there was substantial factories that commercially produced wood vinegar with creosote as a source of acetic acid – - Japan and throughout Asia has used it extensively for several decades for all sorts of uses and replacement of synthetic agrichemicals.
