Pyroligneous acid
A thing for the supernatant liquid of the distillation liquid to occur when I performed distillation of wood with the pyroligneous acid (it is stinking and obtains it and comes). As a representative example, pyroligneous acid is made as a by-product at the time of charcoal making. The appearance is a liquid of the 赤褐 - dark brown. Most are water, but organic acid (acetic acid) derived from wood is included and shows subacidity. As other ingredient, aromatic compounds such as alcohols, carbonyl compounds or phenols and franc are included [1]; [2]. The toxic high materials such as formaldehyde or the benzopyrene are included. Is uneven in an ingredient by the condition of raw materials and the distillation [3]; [4] [5].
"The spirit of a tree" who is another name for methanol comes from that I have been ever provided by the distillation of the pyroligneous acid. The phenols arise from the lignin which is an ingredient of the wood mainly.

Wood distillation industry
Business to prepare sodium acetate as a mordant begins with acetic acid provided by the distillation of the pyroligneous acid from about 1820 in the U.K. [6].
Use
The pyroligneous acid was used to prepare acetic acid and methanol, but, as for the source of supply of those chemical substances, was replaced chemical synthesis or the brewing once.
There are pesticidal use or a folk remedy, the use in the public welfare purpose now.
By the liquid smoking that is one of the food processing methods, 燻液 (with the smoked flavor) obtained from the pyroligneous acid is used.
The pyroligneous acid was registered as an antifungal pesticide in the past, but is a lapse pesticide now because registration lapses (a pesticide registration number: 12850, the kind of the pesticide: pyroligneous acid, the name of the pesticide: Izutsuya Matsune pyroligneous acid, an applicant: Izutsuya, a pesticide registration day: on February 28, 1973 an expiration date: February 28, 1979) [7] [8]. According to Professor Naoki Motoyama of the Chiba University Faculty of Horticulture, the ingredient of the pyroligneous acid has unevenness and announces it to Japan environment animal Entomological Society official journal of a scientific society when there was the mutagenic thing damaging the gene of the microbe among them. [9][10], about the sale of the pyroligneous acid, the sale that declared the effect of the pesticide now is prohibited again by the pesticide control method [11]; [12].
I am sold with the following names, but these are not pesticides with pharmaceutical products either, and the efficacy is not recognized now.
- Pesticidal use
- Evasion of the animal
- Pest measures
- Soil improvement
- The public welfare
- Bathing
- Deodorization
- Sterilization
Charcoal kiln
The charcoal kiln has white charcoal, soft charcoal and is still a tradition kiln succeeded to in each area. Pyroligneous acid provided in those charcoal kilns is used for the public welfare purposes such as bath articles.
