Pinene (C₁₀H₁₆) is a bicyclic monoterpene chemical compound. There are two structural isomers of pinene found in nature: α-pinene and β-pinene. As the name suggests, both forms are important constituents of pine resin; they are also found in the resins of many other conifers, as well as in non-coniferous plants such as camphorweed (Heterotheca) and big sagebrush (Artemisia tridentata). Both isomers are used by many insects in their chemical communication system. The two isomers of pinene constitute the major component of turpentine.

Generating heat within a combination solvent / acid system removes undesirable deposits from petroleum reservoir formations (especially the near well-bore region), oilfield equipment, and petroleum processing equipment. An exothermic reaction occurs between the solvent and the acid and the heat evolved helps remove organic solid deposits. The acids may include organic acid compounds, such as sulfonic acids, sulfuric acid and nitric acid. The solvents may include terpene- and terpene-derivative-containing solvents, including, but not necessarily limited to, limonene, pinene, dipentene, myrcene, turpentines and compounds having at least one double bond, such as methyl furan, dienes, styrene, vinyl acetate and the like.
