Overview
ASTM D1969-22: Standard Specification for 2-Ethylhexanol provides uniform requirements and properties for both regular and monomer grades of 2-ethylhexanol, a key industrial chemical used as a solvent, plasticizer intermediate, and chemical building block. Issued by ASTM International, this standard ensures that 2-ethylhexanol meets consistent physical and chemical properties crucial for industrial use and quality control. The standard outlines the necessary testing methods, sampling procedures, and packaging guidelines to promote safe handling and global trade of this substance.
Key Topics
- Grades Covered: Both regular grade and monomer grade 2-ethylhexanol are specified, catering to a variety of industrial applications.
- Physical and Chemical Properties: The specification establishes requirements for:
- Acidity (as acetic acid)
- Apparent specific gravity (at 20/20°C or 25/25°C)
- Assay (purity)
- Color (Platinum-Cobalt/Pt-Co scale)
- Carbonyl content (as 2-ethylhexanal)
- Ethyl methyl pentanol content
- Sulfuric acid color
- Water content
- Test Methods: Procedures for verifying properties include:
- Color: ASTM D1209 and ASTM D5386
- Acidity, Specific Gravity, Water, Sulfuric Acid Color: ASTM E852, ASTM D4052
- Assay/Purity, Ethyl Methyl Pentanol: ASTM D5008
- Carbonyl Content: ASTM D2119
- Sampling: Sampling must follow ASTM E300 for repeatability and reliability in quality evaluation.
- Packaging & Marking: Packaging must comply with carrier and regulatory requirements or, when specified, follow Federal Specifications like PPP-C-2020.
- Units: All requirements and reported values must be in SI units.
- Hazards: Reference to supplier Material Safety Data Sheets (MSDS) is required for hazard handling guidance.
- Conformance: Rounding and reporting of test results is guided by ASTM E29 for statistical accuracy.
Applications
2-ethylhexanol is widely used in industrial and chemical processes. Adhering to ASTM D1969-22 ensures safety, performance, and regulatory compliance in:
- Plasticizer Production: Essential intermediate in forming plasticizers for polyvinyl chloride (PVC) and other polymers.
- Solvent Use: Key solvent in coatings, inks, and specialty chemical formulations.
- Chemical Synthesis: Used as a precursor in manufacturing other chemical compounds, including surfactants and lubricants.
- Quality Assurance: Standardized testing supports manufacturers, suppliers, and buyers in verifying product quality and meeting contract specifications.
- Global Trade: Facilitates international shipment and acceptance by aligning with WTO Technical Barriers to Trade (TBT) Committee principles.
