CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Dipentene appears as a colorless liquid with an odor of lemon. Flash point 113 °F. Density about 7.2 lb /gal and insoluble in water. Hence floats on water. Vapors heavier than air. Used as a solvent for rosin, waxes, rubber; as a dispersing agent for oils, resins, paints, lacquers, varnishes, and in floor waxes and furniture polishes. |
