ASTM D2106 – Standard Test Methods for Determination of Amine Acid Acceptance (Alkalinity) of Halogenated Organic Solvents
Description:
Significance and Use
4.1 This test method is useful for the determination of the amount of acid acceptance contributed by amines or bases as compared to other acid-accepting compounds.
Scope
1.1 These test methods, where applicable, cover the determination of the acid acceptance of halogenated organic solvents due to the presence therein of an organic amine titratable by standard acid. These test methods are suitable for samples of 0.001 to 0.02 weight percent (10 ppm to 200 ppm) alkalinity as NaOH. Two test methods are covered as follows:
1.1.1 Test Method A—pH Method, and
1.1.2 Test Method B—Indicator Method.
1.1.3 Test Method C—GC Method.
