Diethylene glycol propyl ether acetate

C9H18O4

Diethylene glycol propyl ether acetate, with the chemical formula C9H18O4 and CAS number [XXXXXX], is a glycol ether ester commonly used as a solvent in various industrial and commercial applications. It is derived from the esterification of diethylene glycol propyl ether with acetic acid.

Chemical Structure

The molecule consists of a diethylene glycol backbone (two ethylene oxide units) with a propyl ether group (–OCH2CH2CH3) and an acetate ester group (–OCOCH3) attached. This structure provides a balance of hydrophilic and lipophilic properties, making it an effective solvent for a wide range of materials.

Physical Properties

– Appearance: Typically a clear, colorless liquid.

– Boiling Point: Approximately 220-230°C.

– Density: Around 0.98-1.00 g/cm³.

– Solubility: Miscible with water and many organic solvents, such as alcohols, ketones, and aromatic hydrocarbons.

Chemical Properties

1. Stability: Relatively stable under normal conditions but may hydrolyze in the presence of strong acids or bases.

2. Reactivity: Can participate in typical ester reactions, such as hydrolysis, transesterification, and reduction.

Applications

1. Coatings and Paints: Widely used as a solvent in coatings, paints, and varnishes due to its ability to dissolve resins, polymers, and pigments while providing good flow and leveling properties.

2. Cleaning Agents: Employed in industrial and household cleaning formulations for its solvency and mild odor.

3. Inks and Adhesives: Used as a solvent in printing inks and adhesives to enhance performance and drying characteristics.

4. Electronics: Utilized in the electronics industry for cleaning and degreasing components.

Advantages

– Versatility: Effective solvent for a wide range of substances.

– Low Toxicity: Compared to other solvents, it has relatively low toxicity and mild odor.

– Evaporation Rate: Moderate evaporation rate, making it suitable for applications requiring controlled drying.

Safety and Handling

– Health Hazards: May cause irritation to the skin, eyes, and respiratory system. Prolonged exposure should be avoided.

– Storage: Store in a cool, dry, well-ventilated area away from strong oxidizing agents and sources of ignition.

– Personal Protection: Use appropriate personal protective equipment (PPE), such as gloves and goggles, when handling.

Environmental Considerations

– Biodegradability: Generally considered biodegradable, but should be handled responsibly to minimize environmental impact.

– Regulatory Compliance: Ensure compliance with local regulations regarding use, storage, and disposal.

Conclusion

Diethylene glycol propyl ether acetate is a versatile and effective solvent with applications in coatings, cleaning agents, inks, and electronics. Its balanced properties and relatively low toxicity make it a valuable component in various formulations, though proper handling and storage are essential to ensure safety and performance.
