ASTM D1718-09(2023) PDF

Overview

ASTM D1718-09(2023): Standard Specification for Isobutyl Acetate (95% Grade) defines the requirements and testing methods for isobutyl acetate at a minimum purity level of 95%. This specification, developed by ASTM International, outlines essential physical and chemical property criteria that isobutyl acetate must meet to ensure its suitability for industrial applications. The standard is widely used in the quality assurance of solvents for paints, coatings, chemical formulations, and other manufacturing processes.

Isobutyl acetate is a widely used ester solvent known for its desirable evaporation rate, pleasant odor, and effectiveness as a carrier in various compounds. The ASTM D1718-09(2023) standard supports uniformity in product quality and compliance with international trade requirements by providing precise testing and acceptance criteria.

Key Topics

• Sampling and Testing Requirements

  • Material sampling according to Practice E300.
  • Use of established ASTM test methods for determining conformity (e.g., D1209 for color, D1078 for distillation range, D1353 for nonvolatile matter, D1364 for water content, D1613 for acidity, D3545 for purity, and D4052 for specific gravity).

• Physical and Chemical Property Specifications

  • Apparent Specific Gravity: Must be in the defined range at 20/20 °C (0.868–0.873) or at 25/25 °C (0.864–0.869).
  • Color: Not to exceed 10 Pt-Co units.
  • Distillation Range: Initial boiling point ≥ 112.0°C and dry point ≤ 119.0°C at 760 mmHg.
  • Nonvolatile Matter: Maximum 5 mg/100 mL.
  • Water Content: Maximum 0.1% (by weight).
  • Acidity (as Acetic Acid): Maximum 0.01% (by weight).
  • Purity: Minimum 95% (by weight).

• Rounding and Units

  • Values must be reported in SI units and rounded per Practice E29's guidelines.
  • Only SI units are considered valid within this standard.

• Packaging and Labeling

  • Packaging size and type must be mutually agreed upon between purchaser and supplier.
  • Must comply with applicable transportation regulations or Federal Specification PPP-C-2020 when specified.

• Safety

  • Users must refer to the supplier’s Safety Data Sheet for hazards and handling guidance.

Applications

• Paints and Coatings: Isobutyl acetate is a key solvent in the formulation of paints, varnishes, and lacquers, facilitating proper flow and drying times.
• Chemical Manufacturing: The specification ensures consistent quality for producers of adhesives, resins, extractants, and other chemical intermediates.
• Industrial Solvents: Used in blends for cleaning, degreasing, and specialty solutions, the standard ensures performance and safety.
• Pharmaceutical and Perfume Industries: Ensures the isobutyl acetate meets required purity for sensitive applications.
• International Trade: Meeting ASTM D1718-09(2023) facilitates cross-border commerce by assuring buyers of product quality and compliance.
