Reactivity
D-LIMONENE is sensitive to exposure to light. Atmospheric oxidation can occur. This chemical is incompatible with strong oxidizing agents. It reacts violently with (iodine pentafluoride + tetrafluoroethylene). With dry hydrogen chloride or hydrogen bromide, it forms monohalides. With aqueous hydrogen chloride or hydrogen bromide, it forms the dihalide. (NTP, 1992)
