    Abstract: Tools and techniques for pyroligneous acid production are provided in accordance with various embodiments. For example, a method of pyroligneous acid production is provided. The method may include: introducing a compound that includes at least carbon, oxygen, and hydrogen into a reaction chamber; heating the compound to a temperature of at least 700 degrees Celsius in the reaction chamber such that the compound reacts through a pyrolysis reaction to produce a liquid, where the liquid may include pyroligneous acid; and/or collecting the produced liquid. In some cases, the residence time of the compound may be less than 1,000 seconds. Temperatures above 1,000 degrees Celsius may be utilized in some cases. The produced liquid may be separated into an oil component and a water component that includes the pyroligneous acid. A lighter fraction may be distilled from the water component, where the lighter component includes the pyroligneous acid.
