Product Category: Polyether industrial solvent, polyester plasticizer intermediate, antifreeze raw material, textile printing auxiliary, dehydration absorbent
2. Physical and Chemical Properties
Physical Indicators
- Appearance: Colorless transparent viscous liquid
- Odor: Odorless, slight sweet taste
- Solubility: Fully miscible with water, ethanol, methanol, acetone and glycerin; slightly soluble in aromatic hydrocarbons; insoluble in aliphatic mineral oil
- Melting Point: -10.5 °C
- Boiling Point: 244–246 °C (760 mmHg)
- Density (20 °C): 1.116–1.119 g/cm3
- Refractive Index (20 °C): 1.447–1.449
- Flash Point: 124 °C
- Hygroscopicity: Strongly hygroscopic under high humidity air
- Aqueous Stability: Stable under neutral and weakly acidic conditions; slow hydrolysis will not occur at room temperature
Chemical Characteristics
- Molecular Structure: Two ethanol units connected by ether bond, containing two terminal hydroxyl groups
- Core Functional Mechanism: High boiling polar hygroscopic solvent; used to synthesize polyester resins, plasticizers and surfactants; industrial antifreeze component; textile dyeing leveling agent
- Photostability: Stable under sealed dark storage, no obvious light-induced discoloration
- Thermal Stability: Stable below 180 °C; long-term heating above 220 °C triggers dehydration and oxidative decomposition
- Chemical Compatibility: Compatible with most neutral solvents, resins and emulsifiers; incompatible with strong oxidants and concentrated strong alkalis under high temperature
3. Main Application Fields
