Description

General description

Ethane, an aliphatic hydrocarbon, is a major constituent of natural and shale gas. It is a major feedstock for the preparation of ethylene and other value-added chemicals like aromatic hydrocarbons.[1][2][3]

Application

Ethane can be used to prepare:

• Ethylene via oxidative dehydrogenation reaction using different catalytic systems.[4][5]
• Ethanol via oxidation reaction, which is catalyzed by cytochrome P450 BM3.[6]
• Carbon nanofibers via decomposition method using nickel catalyst supported by a carbon nanotube.[7]

Packaging

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

Compatible with the following:

• Aldrich^® lecture-bottle station systems
• Aldrich^® lecture-bottle gas regulators
