64-17-5 | Ethanol

Chemical type

• Biofuel
• Oxygenated hydrocarbon
• Bio-derived oxygenated hydrocarbon

^[1]

• Alcohol
• Solvent

^[2]

Key properties

• Reduces CO₂ emissions through carbon-neutral energy balance
• Reduces soot emissions at higher blending ratios (above 40 vol%)
• Shows synergistic effect increasing soot formation at low blending ratios (10-20 vol%)
• Enhances fuel oxidation and decomposition via pyrolysis, producing methyl radicals (CH₃)
• Non-monotonic impact on soot precursors and particle size, with little effect up to 10 vol% but significant reduction at higher levels
• Increases flame temperature marginally when blended
• Lowers C/H and C/O atomic ratios in fuel mixtures

^[1]

• Dehydrating agent, disinfectant.
• Volatile, miscible with water.

^[2]

• Blended with gasoline for spark-ignition engines
• Alternative to fossil fuels in transport sectors
• Fuel additive to reduce climate-impacting pollutants like soot

^[1]

• Tissue dehydration through a graded series (e.g., for paraffin embedding).
• Sample storage (e.g., 70% ethanol).

Classification by use

• Biofuels for emission reduction
• Oxygenated fuel additives in combustion applications
• Blended fuels for laminar flame studies
