(-)-CAMPHOR Chemical Properties,Usage,Production

Uses

(1S,4S)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-one also known by its common name as (-)-Camphor is a chiral intermediate of camphor and is used as a flavour additive in foods and sweetners.

Chemical Properties

white crystals

Uses

(1S)-(-)-Camphor is used as chiral intermediate and chiral auxiliary precursor. It is used in the synthesis of high-potency sweeteners. It acts as catalytic agent and petrochemical additive.

Definition

ChEBI: The S-enantiomer of camphor.

General Description

Colorless or white crystals. Fragrant and penetrating odor. Slightly bitter and cooling taste. Odor index at 68°F: 40. Flash point 149°F. Burns with a bright, smoky flame. Sublimes appreciably at room temperature and pressure; 14% sublimes within 60 minutes at 176°F and 12 mm Hg.

Air & Water Reactions

Flammable. Slightly water soluble.

Reactivity Profile

(-)-CAMPHOR may be sensitive to heat and direct sunlight. Incompatible with strong oxidizing agents, strong reducing agents and chlorinated solvents. Also incompatible with potassium permanganate. Salts of any kind should not be added to (-)-CAMPHOR in water. Reacts violently with chromic anhydride .

Fire Hazard

(-)-CAMPHOR is flammable.

Purification Methods

Crystallise it from EtOH, 50% EtOH/water, MeOH, or pet ether or from glacial acetic acid by addition of water. It can be sublimed (50o/14mm) and also fractionally crystallised from its own melt. It is steam volatile. It should be stored in tight containers as it is appreciably volatile at room temperature. The solubility is 0.1% (H2O), 100% (EtOH), 173% (Et2O) and 300%
