This standard is essential for the analysis of aliphatic amines, diamines, and their derivatives, which are widely used in:

: This is determined by reacting the primary amines in the sample with salicylaldehyde. This reaction blocks the primary amine groups, allowing any remaining secondary or tertiary amines to be titrated. The primary amine value is then calculated by the difference between the total amine value and the remaining amine value.

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.

Having the current version of the PDF on file is mandatory for passing audits from bodies like ISO 9001, OSHA, or specific environmental protection agencies.

: Including drilling fluids, engine oils, coolants, and hydraulic fluids where amines serve as acid neutralizers. astm d2074 pdf

Technicians must wear nitrile or chemical-resistant gloves, safety goggles, and standard laboratory coats.

The ASTM D2074 PDF test method offers several advantages, including:

If you are running a modern commercial lab, focus on implementing Method B described in the standard for efficiency and safety. If you are a small operation or an academic setting with limited funds but plenty of glassware, Method A remains a viable and robust standard.

[ Sample Preparation ] │ ├──> Titration 1: Total Amine Value (Direct titration with Acid) │ ├──> Titration 2: Secondary + Tertiary Amine Value (Salicylaldehyde blocks Primary Amines) │ └──> Titration 3: Tertiary Amine Value Only (Acetic Anhydride blocks Primary & Secondary Amines) This standard is essential for the analysis of

utilizes potentiometric titration . It requires an automated titrator equipped with glass and reference electrodes to map the pH/millivolt inflection curve.

Weigh a precise amount of the fatty amine sample and dissolve it in a warm mixture of isopropyl alcohol and toluene.

The method is specifically designed for used in industrial products such as:

Accessing the official ASTM D2074 PDF is necessary for lab compliance and accuracy for several reasons: The chemical manufacturing and quality control sectors rely

The standard outlines the use of specific alcohols. Always ensure your solvents are free of carbon dioxide and water, as these can interfere with the endpoint of the indicator.

: You can also find the PDF on platforms like the ANSI Webstore or DIN Media .
