Astm D2074 Pdf [better] -
The use of high-purity reagents is critical for obtaining accurate results. The standard specifies that reagent-grade chemicals must be used, and water must conform to Type II specifications of ASTM D1193. The specific reagents called for include:
The standard's primary function is to define the indicator procedure for determining the total, primary, secondary, and tertiary amine values of fatty amines. The results are expressed in the (mg KOH/g).
No. ASTM D2074 was officially withdrawn in the early 2020s. The last active edition was D2074‑07(2019). No further reapprovals or revisions will occur.

Note: Ensure you are using the most current version, which is currently the 2007 (2019) revision, to ensure accurate results. Conclusion
Fatty amines are nitrogen-containing derivatives of fatty acids. They serve as critical intermediates in manufacturing surfactants, corrosion inhibitors, asphalt emulsifiers, and fabric softeners.
The standard establishes the statistical margins of error allowed between different operators in the same lab (repeatability) and different laboratories (reproducibility). How to Access the Official ASTM D2074 PDF The results are expressed in the (mg KOH/g)
Further isolation involves reacting the sample with acetic anhydride, which acetylates both primary and secondary amines, leaving only the tertiary amines basic. Titration then reveals the tertiary amine value. Through a process of elimination and mathematical subtraction, lab technicians can precisely calculate the distinct values for all three amine types. Key Reagents and Apparatus Required
This step measures the combined basicity of all primary, secondary, and tertiary amines present in the fatty amine sample. The sample is typically dissolved in a suitable solvent (such as isopropyl alcohol) and titrated against a standardized acid solution (usually hydrochloric acid, HCl) using a color indicator to signal the endpoint. 2. Primary Amine Value
Always check if the version you are purchasing is the active standard or a historical version, as ASTM regularly reviews and reapproves or updates methods every few years.
The chemical manufacturing and quality control sectors rely heavily on standardized testing to ensure the purity, consistency, and performance of raw materials. In the surfactant and oleochemical industries, fatty amines serve as critical building blocks for surfactants, corrosion inhibitors, fabric softeners, and asphalt emulsifiers.
When evaluating the ASTM D2074 protocol, laboratory personnel focus on several critical parameters: Specification / Requirement Fatty amines, fatty diamines Primary Reagents
