Description

General description

Propane is an aliphatic hydrocarbon obtained during the oil and natural gas processing. It is generally used as a fuel in automobiles and LPG. It serves as a raw material for the modern chemical industry.[1][2]

Application

Propane can be used as:

• A substrate in the study of oxidative dehydrogenation using carbon nanofiber-based catalysts[3] and zeolite catalysts.[4]
• A component of a binary system along with CO₂ to study the solubility of some fat-soluble vitamins.[5]

Packaging

Supplied in a carbon steel lecture bottle with a CGA180M/CGA110F needle valve installed.
