Gummo-oleoresins (oleo-gum resins, gum resins) occur mostly as crude balsams and contain also water-soluble gums. Processing of oleoresins is conducted on a large scale, especially in China (400,000 tons per year in the 1990s), but the technology is too labor-intensive to be viable in countries with high labor costs, such as the US.
Such turpentine is called gum turpentine. [11] The term gum turpentine may also refer to crude turpentine, which may cause some confusion. 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 ...
