Pyroligneous acid, also called wood vinegar[3][4] or wood acid,[5] is a dark liquid produced through the natural act of carbonization, which occurs when wood is heated in an airless container during charcoal production, such as pyrolysis.
Chemical components
The principal components of pyroligneous acid are acetic acid, acetone and methanol. It was once used as a commercial source for acetic acid. In addition, the vinegar often contains 80-90% water along with some 200 organic compounds.
Food Preservation
During the United States Civil War it became increasingly difficult for the Confederate States of America to obtain much needed salt. Curing meat and fish with pyroligneous acid was attempted by cooks to compensate for this deficiency. Unfortunately for the Confederate States Army it was not a comparable method of food preservation. [6]
