Ethane is an organic chemical compound, with the formula C2H6.
Contents
Properties
Chemical
Ethane will burn in an oxygen atmosphere to release carbon dioxide and water vapor.
- C2H6 + 7/2 O2 → 2 CO2 + 3 H2O
Physical
Ethane is a colorless, odorless gas at standard conditions.
Availability
Ethane can be purchased in compressed gas cylinders.
Preparation
Ethane can be prepared from electrolysis of acetic acid or potassium acetate, process known as Kolbe electrolysis. It can also be prepared by heating a mixture of sodium propionate with sodium hydroxide.
Projects
- Make ethylene
- Haloethanes
- Fuel
Handling
Safety
Ethane is non toxic, though in high quantities it can be asphyxiant. When mixed with air, at 3.0%–12.5% by volume, in an enclosed chamber, it may explode.
Storage
Liquified ethane should be stored away from heat sources.
Disposal
Ethane is not dangerous for environment, though it can contribute to global warming. It can safely be burned, as it produces just carbon dioxide and water vapor.
