General information
Acid Value Determination
The acid number characterises the acidic components of the fats. For this purpose, the sample is dissolved in a solvent and titrated against phenolphthalein with potassium hydroxide solution. Only free fatty acids are recorded. The fatty acids bound in the glycerides are not determined.
Indicators and Dyes
Carl ROTH offers many indicators and dyes of high purity, which can be used in special applications.
