in 1 vol of 95% ethanol; solutions usually become cloudy on further dilution. In addition to monoterpene hydrocarbons, this oil contains up to 35%
1,8-cineole.

反応プロフィール
White camphor oil containing ether can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.
