ASTM D2110-00 (2022) PDF

Full title and description

ASTM D2110-00(2022) — Standard Test Method for pH of Water Extractions of Halogenated Organic Solvents and Their Admixtures. This test method describes preparation of an aqueous extract of a halogenated organic solvent (or solvent blend) and measurement of the pH of the water layer to assess solvent stabilizers, contamination, or degradation for quality control, reclamation and troubleshooting purposes.

Abstract

Provides two procedures for determining the pH of water extractions from halogenated organic solvents: Procedure A using color indicators for approximate pH (reported to 0.25 pH unit) and Procedure B using a glass-electrode pH meter for more precise measurement (reported to 0.1 pH unit). The method is intended for virgin, reclaimed, or used halogenated solvents and helps detect changes in stabilization or contamination.

General information

• Status: Active (reaffirmed / updated designation reported 2022).
• Publication date: D2110-00 originally issued 2000; active/reaffirmed entry dated May 9, 2022.
• Publisher: ASTM International (Committee D26, Subcommittee D26.04).
• ICS / categories: Petroleum and related technologies (ICS 75 — petroleum and related technologies) and chemical/petrochemical test methods (relevant committee: ASTM D26).
• Edition / version: Designation D2110-00 with 2022 reaffirmation (often shown as D2110-00(2022) or D2110-00R22).
• Number of pages: Brief method — typically published as a short procedure (ASTM listing shows 2 pages).

Scope

This test method covers measurement of the pH of aqueous extracts of halogenated organic solvents and their admixtures and is applicable to virgin, reclaimed, or used solvents. It specifies extraction of water from the solvent, separation of layers, and measurement either by indicator (Procedure A) or by pH electrode (Procedure B). The standard notes it does not address all safety concerns and that users must apply appropriate safety, health, and environmental practices.

Key topics and requirements

• Sample extraction: mixing a measured volume of distilled/deionized water with the solvent and allowing phase separation to obtain the aqueous layer for measurement.
• Procedure A — color indicator: use of a suitable acid–base indicator and reporting to the nearest 0.25 pH unit for approximate screening.
• Procedure B — glass electrode: direct measurement with a pH meter and glass electrode, reporting to the nearest 0.1 pH unit for greater precision.
• Interpretation: typical solvent stabilizers produce characteristic pH ranges (e.g., amine-type stabilizers tending alkaline, epoxide-type stabilizers nearer neutral); deviations may indicate contamination or degradation.
• Reporting and precision: method specifies which procedure was used, reporting resolution, and any deviations from the procedure.

Typical use and users

Quality-control and analytical laboratories in chemical manufacturing, solvent producers and reclaimers, petrochemical and lubricant laboratories, environmental testing labs, and service labs performing incoming/outgoing solvent checks or troubleshooting solvent performance. Used for routine QC, reclamation assessment, and investigation of solvent breakdown or contamination.

Related standards

Standards commonly referenced alongside D2110 include other ASTM methods for solvent acidity/alkalinity and residues such as ASTM D1093 (acidity of water layer and distillation residues), ASTM D2109 (non-volatile residue), ASTM D2942 (total acid of halogenated organic solvents), ASTM D2989 (acidity-alkalinity of halogenated solvents/mixtures), and more general pH methods such as ASTM E70. These related methods aid deeper evaluation when D2110 indicates unusual pH values.

Q: What does it cover?

A: It covers preparing a water extraction from a halogenated solvent, separating the aqueous layer, and determining the pH either by indicator (Procedure A) or by pH electrode (Procedure B), with specified reporting precision and general applicability to virgin, reclaimed, or used solvents.

Q: Who typically uses it?

A: Chemical and solvent manufacturers, reclaimers, petrochemical labs, contract testing laboratories, and quality-control personnel who need to monitor stabilizer levels, contamination, or degradation of halogenated solvents.
