    Turpentine may alternatively be extracted from destructive distillation of pine wood, [3] such as shredded pine stumps, roots, and slash, using the light end of the heavy naphtha fraction (boiling between 90 and 115 °C or 195 and 240 °F) from a crude oil refinery. Such turpentine is called wood turpentine.

    Chemical methods include prophylactic stump treatment with a solution of urea immediately after the infection. This protects the stump by hydrolysis of the compound by the enzyme urease in the living wood tissue, which results in formation of ammonia and a rise in pH to a level that H. annosum at which mycelia are unable to survive. Biological ...

  8. Wood preservation - Wikipedia

    en.wikipedia.org/wiki/Wood_preservation

    The physical properties of any material are determined by its chemical structure. Wood contains an abundance of chemical groups called free hydroxyls. Free hydroxyl groups readily absorb and release water according to changes in the climatic conditions to which they are exposed. This is the main reason why wood's dimensional stability is ...

  9. Piranha solution - Wikipedia
