A type of essential oil, it is an important industrial raw material. Turpentine is a liquid extracted from the resin of coniferous plants through distillation or other methods, primarily composed of terpenes. Turpentine can be mixed with diluents or acetic acid in any proportion but is not soluble in water. It is a highly flammable liquid with a high flash point, volatile, and produces a large amount of dense smoke when burned.
