Product Overview
Diethylene glycol (DEG) is a colorless, odorless, and hygroscopic liquid with the molecular formula C4H10O3, offering exceptional solvent properties for laboratory applications. This high-purity (99%+) reagent-grade chemical exhibits excellent miscibility with water, alcohols, and many organic solvents, making it versatile for chemical synthesis, extraction processes, and as a humectant in formulations. Its moderate viscosity and high boiling point (245°C) provide stability in various reaction conditions. DEG serves as an effective intermediate in polyester production and as a dehydrating agent in gas processing. The chemical’s low volatility and hygroscopic nature require proper storage in tightly sealed containers to prevent moisture absorption. As a laboratory staple, it maintains consistent performance in analytical procedures and industrial research applications. The product meets stringent quality standards for purity and consistency, ensuring reliable results in critical experiments.
FAQs
1. What is the shelf life of diethylene glycol when stored properly?
When stored in a cool, dry place in its original tightly sealed container, diethylene glycol typically maintains its stability for 2-3 years from the date of manufacture.
2. Can this grade of diethylene glycol be used in food or pharmaceutical applications?
This laboratory reagent grade is not certified for food, pharmaceutical, or medical use. For those applications, you would need pharmaceutical-grade or food-grade diethylene glycol with appropriate certifications.
3. What safety precautions should be taken when handling diethylene glycol?
Always wear appropriate personal protective equipment including gloves, goggles, and lab coat. Work in a well-ventilated area or under a fume hood, as prolonged exposure may cause skin and eye irritation.
4. How does diethylene glycol differ from ethylene glycol in terms of properties?
Diethylene glycol has a higher boiling point (245°C vs 197°C), lower volatility, and is less toxic than ethylene glycol. It’s also more viscous and has better humectant properties.
5. What type of container material is recommended for long-term storage?
High-density polyethylene (HDPE) or glass containers are recommended for storage. Avoid metal containers as they may react with the chemical over time.
