Standard Test Method for Total Acid Acceptance of Halogenated Organic Solvents (Nonreflux Methods)


1.1 This test method covers the determination of the total acid acceptance including amine and neutral type (alpha epoxide) stabilizers in halogenated organic solvents.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 7.

Significance and Use

p>Solvents that have been depleted in stabilizer content can become acidic. Acids can cause corrosion to process and storage equipment used for halogenated solvents.

Halogenated organic solvents may contain amine type (alkaline, aqueous extractable) acid accepting additives, neutral type (typically epoxide) acid accepting additives or both. This test method can determine the combined acid acceptance from both types of stabilizers. In addition, if the amine acid acceptance is determined by a separate procedure (see Test Methods D 2106), the amount of neutral acid accepting stabilizers in a solvent can be calculated from the difference between combined and amine acid acceptance values.

This test method may be used by producers and users to verify that a product is complying with acid acceptance product specifications or by users to monitor the acid accepting ability of a solvent in use.
