- Display Name:
- Gases (petroleum), C3-4, isobutane-rich
- EC Number:
- 270-724-1
- EC Name:
- Gases (petroleum), C3-4, isobutane-rich
- CAS Number:
- 68477-33-8
- Molecular formula:
- It is a complex combination of hydrocarbons produced by the distillation of the products of a steam cracking process that were further processed. It consists predominantly of hydrocarbons having a carbon number of C3-4, predominantly isobutene, containing also propane, 1-butene and 2-butene, butane, pentane and isobutene and boiling in the range of approximately minus 12°C to 5°C (10.4°F to 41°F). Therefore it is not possible to define a molecular formula, a molecular weight, a SMILES-notation or a structural formula.
