D1007-11 – Standard Test Method Technical Guide
📜 Scope and Applicability
This specification covers sec-butyl alcohol (also known as 2-butanol and secondary butanol) for use in paint, varnish, lacquer, and related products. The standard values are stated in SI units, and all specified limits are evaluated in accordance with the rounding-off method of Practice E29. For hazard information, refer to the supplier’s Material Safety Data Sheet. This international standard adheres to globally recognized principles for standardization.
🔬 Property Specifications and Limits
Sec-butyl alcohol must meet the following property requirements when tested in accordance with the specified ASTM test methods.
| 🟦 Property | 📏 Requirement | 🎯 Test Method |
|---|---|---|
| Apparent Specific Gravity (20/20 °C) | 0.807 to 0.809 | D4052 |
| Apparent Specific Gravity (25/25 °C) | 0.804 to 0.806 | D4052 |
| Color, Pt-Co scale, max | 10 | D1209 or D5386 |
| Distillation Range (760 mmHg): Initial Boiling Point, min | 98.0 °C | D1078 |
| Distillation Range (760 mmHg): Dry Point, max | 101.0 °C | D1078 |
| Nonvolatile Matter, max | 5 mg/100 mL | D1353 |
| Water, max | 0.5 weight % | D1364 |
| Acidity (as acetic acid), max | 0.002 weight % | D1613 |
Note: Instrumental Pt-Co color determined by Test Method D5386 has been shown to have no statistically significant difference from color determined by Test Method D1209.
💡 When rounding test results for conformance, use the rounding-off method of Practice E29—always round to the nearest unit in the last right-hand digit of the specification limit.
⚙️ Sampling and Testing Requirements
Sampling of sec-butyl alcohol must be performed in accordance with Practice E300. The following ASTM test methods are referenced for determining the properties listed above.
- D268 – Guide for Sampling and Testing Volatile Solvents
- D1078 – Distillation Range
- D1209 – Color (Platinum-Cobalt Scale)
- D1353 – Nonvolatile Matter
- D1364 – Water (Karl Fischer Titration)
- D1613 – Acidity
- D4052 – Density and Specific Gravity
- D5386 – Color (Tristimulus Colorimetry)
The material must conform to all specified limits for use in paint, varnish, lacquer, and related coatings.
⚠️ Always consult the supplier’s Material Safety Data Sheet (MSDS) for comprehensive hazard information and handling guidance for sec-butyl alcohol.
❓ Frequently Asked Questions
🔍 What is sec-butyl alcohol and where is it used?
Sec-butyl alcohol, also known as 2-butanol or secondary butanol, is a volatile solvent primarily used in paint, varnish, lacquer, and related products to improve viscosity and drying properties.
💡 How is the water content specified in D1007-11?
The standard requires that water content in sec-butyl alcohol not exceed 0.5% by weight, as determined by Test Method D1364 (Karl Fischer Reagent Titration).
⚡ What are the key acidity limits for sec-butyl alcohol?
Acidity, calculated as acetic acid, must not exceed 0.002% by weight. This is equivalent to 0.019 mg of KOH per gram of sample, measured per Test Method D1613.
📌 What is the significance of the distillation range requirement?
The distillation range ensures purity and consistency: the initial boiling point must be at least 98.0°C and the dry point no higher than 101.0°C at 760 mmHg, tested in accordance with D1078.
