White camphor oil

Химические свойства

White camphor oil is the first distillation fraction (about 20% of the crude camphor oil). It is a colorless or almost colorless liquid with a cineole-like odor. d²⁵₂₅ 0.855–0.875; n²⁰_D 1.4670–1.4720; α_D +16° to +28°; solubility: 1 vol 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.

Физические свойства

A white viscous liquid.

Общее описание

A colorless liquid with a characteristic odor. Flash point 125°F. Insoluble in water and generally less dense than water. Vapors heavier than air.

Реакции воздуха и воды

Flammable. Insoluble in water.

Профиль реактивности

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.

Угроза здоровью

Within 5 to 90 minutes after swallowing, the following may be noted: nausea and vomiting; feeling of warmth; headache; confusion, vertigo, excitement, restlessness, delirium, and hallucinations; increased muscular excitability, tremors, and jerky movements; epileptiform convulsions, followed by depression (convulsions sometimes occur early in the syndrome and may be severe, but they do not have the grave prognosis of strychnine convulsions); coma; central nervous depression may at times be the primary clinical response; death results from respiratory failure or from status epilepticus; slow convalescence (days or weeks), often with persistent gastric distress.

Пожароопасность

Behavior in Fire: The solid often evaporates without first melting.

Профиль безопасности

A human poison by ingestion. Human systemic effects by ingestion: convulsions, tremors, and unspecified respiratory system effects. A skin irritant. Flammable liquid when exposed to heat or flame; can react with oxidzing materials. To fight fire, use foam, CO2, dry chemical, mist, fog. See also SAFROL and CAMPHOR.

Возможный контакт

Camphor, a natural product, is used as a plasticizer for cellulose esters and ethers; it is used in lacquers and varnishes; and in explosives and pyrotechnics formulations. It is used as a moth repellent and as a medicinal.
