Astm D2074: Pdf _best_

ASTM D2074-07(2019) outlines the Alternative Indicator Method for determining total, primary, secondary, and tertiary amine values in fatty amines, specifically excluding amidoamines and diamines. The procedure utilizes specific chemical indicators, such as bromphenol blue, to measure amine basicity through titration. Purchase the full standard on the ASTM International ASTM International

• Copyright Infringement: ASTM actively pursues legal action against websites hosting copyrighted standards. Downloading these could expose your company to liability.
• Outdated Versions: Many free sites host scanned copies from the 1990s or early 2000s. ASTM updates standards regularly. Using an obsolete version (e.g., D2074 – 07 instead of D2074 – 22) can void quality certifications like ISO 9001.
• Poor Quality: Scans are often illegible, missing annexes, or contain calculation errors.

The current version of the standard is ASTM D2074-07(2019), which was reapproved in 2019. It defines the specific methods used to measure the basicity of fatty amines, expressed as the "amine value"—the number of milligrams of potassium hydroxide (KOH) equivalent to the amine basicity in one gram of sample. The standard focuses on four specific values: Total Amine Value: Total basicity of the sample. difatty secondary amines

Target Materials: The method is applicable to materials containing fatty primary amines, difatty secondary amines, and trifatty tertiary amines.
