Beschreibung

Allgemeine Beschreibung

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]

Anwendung

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]

Verpackung

Packaged in carbon steel lecture bottles with CGA 110F/180M Al-Si-Bronze needle valve.
