Determination of low-level total acid number in mineral oils and biodiesel and low-level free fatty acid content in edible fats and oils

Metrohm’s application chemists regularly participate in scientific conferences where they present the latest results of their research in technical posters.

These posters comprise condensed information on instrumentation, sample preparation, analysis, and results.

Intro

8.000.6050 Determination of low-level total acid number in mineral oils and biodiesel and low-level free fatty acid content in edible fats and oils
The determination of the total acid number (TAN) in mineral oils and the free fatty acid (FFA) content in edible fats and oils both involve the titration of weakly acidic species in non-aqueous media with a dilute solution of a strong base in alcohol as the titrant. A new thermometric titration procedure overcomes inherent problems with the current manual and potentiometric methods.
