Heptane or n-heptane is the straight-chain alkane with the chemical formula C7H16.
Contents
Properties
Chemical
Heptane will burn when ignited in air.
Physical
Heptane is a colorless liquid with a petroleum-like odor.
Availability
Certain types of lighter fluids contain heptane.
Car starting fluids contain a mixture of heptane and diethyl ether. Due to the large difference between their boiling points, the mixture can be separated by first distilling the ether, and then the heptane. However, some formulas may also contain other isomers of heptane, making the extraction of the pure n-heptane complicated.
Preparation
Heptane can be prepared by reducing heptane derivates. However it is generally much cheaper to simply buy the compound.
Projects
- Identify aqueous bromine from iodine
- Organic extractions
Handling
Safety
Heptane is flammable and it's vapors may be irritant if inhaled.
Storage
Heptane is best stored in closed bottles, kept in cold, dark and well ventilated places.
Disposal
Heptane can be safely burned in open air or in an incinerator.
