ASTM D2074

Understanding is essential for laboratory professionals and chemical manufacturers who need to quantify the basicity of fatty amines. This standard, titled Standard Test Methods for Total, Primary, Secondary, and Tertiary Amine Values of Fatty Amines by Alternative Indicator Method , provides a reliable alternative to traditional potentiometric titration.

Total Amine Value:

Titrated with HCl using bromphenol blue or bromcresol green indicators. astm d2074 pdf

Rating:

1. Scope: Defines the scope of the test methods and the types of oils and greases that can be analyzed.
2. Referenced Documents: Lists the documents referenced in the standard, including other ASTM standards and publications.
3. Terminology: Defines the terms used in the standard.
4. Apparatus and Reagents: Describes the equipment and reagents required for the test methods.
5. Test Methods:

   using an alternative indicator method. It is primarily utilized in the chemical and surfactant industries to measure the alkalinity or nitrogen content of these substances. Key Aspects of ASTM D2074 Scope: Defines the scope of the test methods

   • Accuracy: The standard is generally considered highly accurate when performed by trained technicians. However, the results can be matrix-dependent. Peat is an organic material that can vary widely in composition, so the standard emphasizes the importance of representative sampling.
   • Precision: ASTM standards typically provide interlaboratory precision data (repeatability and reproducibility). Users generally find that Method B (Instrumental) offers excellent precision, often better than Method A, provided the instrument is properly calibrated with suitable reference materials.

   3. Secondary Amine Value

   That’s where comes in. Known formally as the Standard Test Methods for Total, Primary, Secondary, and Tertiary Amine Values of Fatty Amines by Alternative Indicator Method , this standard provides a critical chemical "fingerprint" for these vital compounds.
