Why is isobutanol (cas 78-83-1) better than ethanol (cas 64-17-5)?
Isobutanol is not "better" than ethanol in all circumstances, but it is a technically superior biofuel for replacing gasoline. Its chemical properties more closely resemble those of gasoline, solving many of the logistical and performance issues associated with ethanol, such as low energy density, corrosiveness, and incompatibility with pipelines.
| Property | Isobutanol | Ethanol | Advantage |
|---|---|---|---|
| Energy Content | ~105,000 BTU/gal | ~76,000 BTU/gal | Isobutanol (Better mileage) |
| Hygroscopicity | Low | High | Isobutanol (No phase separation, less corrosion) |
| Vapor Pressure | Low | High | Isobutanol (Fewer evaporative emissions) |
| Blend Wall | High (can be blended >16%) | Low (~10-15% in standard engines) | Isobutanol (Drop-in biofuel) |
| Pipeline Transport | Compatible | Not Compatible | Isobutanol (Uses existing infrastructure) |
| Production Cost | Higher | Lower | Ethanol (Cheaper, mature technology) |
| Octane Rating | ~103 | ~113 | Ethanol (Better for engine performance) |
