    • n Isoprene (Chem) An oily, volatile unsaturated hydrocarbon (C5H8), obtained by the distillation of caoutchouc or gutta-percha, and used to make synthetic rubber by polymerization. In organic chemistry, it is viewed conceptually as the building block of the terpene series of hydrocarbons.

    • n isoprene A hydrocarbon (C5-H8), one of the hemiterpenes, produced in the destructive distillation of india-rubber or gutta-percha, and also obtainable from oil of turpentine. It is a colorless, highly volatile liquid, which as special interest from the fact that it is converted into india-rubber by prolonged contact at ordinary temperature with strong hydrochloric acid or nitrosyl chlorid.
