Distinction of n-alkanols in biodiesel fuel by diffusion-ordered NMR spectroscopy

Key Points

• NMR spectroscopy effectively identifies different n-alkanol components in biodiesel blends, proving its utility in fuel analysis.
• The analysis shows distinct molecular interactions based on diffusion properties of n-alkanols, enhancing biodiesel quality assessment.
• Using advanced diffusion-ordered NMR spectroscopy techniques allows for precise identification of n-alkanols within biodiesel products.
• This method may enable better biodiesel quality control and formulation standards in renewable energy sectors.
