pi·nene P0312400 (pī′nēn′)n. Either of two volatile isomeric terpene liquids, C10H16, which are the major constituents of turpentine and are used as solvents and in making resins.pinene (ˈpaɪniːn) n (Elements & Compounds) either of two isomeric terpenes, found in many essential oils and constituting the main part of oil of turpentine. The commonest structural isomer (α-pinene) is used in the manufacture of camphor, solvents, plastics, and insecticides. Formula: C10H16[C20: from pine1 + -ene]pi•nene (ˈpaɪ nin) n. a liquid terpene, C10H16, the principal constituent of oil of turpentine, used chiefly in the manufacture of camphor. [1880–85]
