ASTM D2074 – Standard Test Methods for Total, Primary, Secondary, and Tertiary Amine Values of Fatty Amines by Alternative Indicator Method

Description:

Abstract

These alternative test methods cover the indicator procedure for determining the total, primary, secondary, and tertiary amine values of fatty amines. These procedures are not applicable to fatty amidoamines and fatty diamines. The apparatus includes Erlenmeyer flasks and magnetic stirrer. Reagent grade chemicals shall be used in all tests and includes the following: water, bromphenol blue indicator solution, bromcresol green indicator solution, chloroform, hydrochloric acid standard solution, isopropyl alcohol, phenyl isothiocyanate, and salicylaldehyde. The procedure of determining the total amine values are detailed and the formula of calculating the total amine values is given.

Scope

1.1 These alternative test methods cover the indicator procedure for determining the total, primary, secondary, and tertiary amine values of fatty amines. These procedures are not applicable to fatty amidoamines and fatty diamines.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
