General Description
A colorless liquid with a characteristic odor. Flash point 125°F. Insoluble in water and generally less dense than water. Vapors heavier than air.
Air & Water Reactions
Flammable. Insoluble in water.
Reactivity Profile
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.
Health Hazard
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.
Fire Hazard
Behavior in Fire: The solid often evaporates without first melting.
Potential Exposure
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.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Shipping
UN2717 Camphor, synthetic, Hazard Class: 4.1;
Labels: 4.1-Flammable solid. UN1130 camphor oil, Hazard
Class: 3; Labels: 3-Flammable liquid
Incompatibilities
May form explosive mixture with air.
Violent, possibly explosive, reaction with strong oxidizers,
especially chromic anhydride, potassium permanganate.
May accumulate static electrical charges, and may cause
ignition of its vapors.
Chemical Properties
Camphor is a colorless glassy solid. Penetrating, characteristic odor.
Chemical Properties
The oil is produced by fractional distillation of the crude camphor oil after the camphor has been crystallized. It is
obtained from the bark and tree. The white oil contains cineole as the principal component along with monoterpenes.
Chemical Properties
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; n20D 1.4670–1.4720; αD +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.
Waste Disposal
ncineration of a solution in a
flammable solven.
Physical properties
A white viscous liquid.
