Molecular Formula: C4H10O2
Molecular Weight: 90.12
Synonyms: 1,4-Butylene glycol, Tetramethylene glycol, BDO
Product Category: Polyurethane monomer, PBT resin raw material, cosmetic humectant, organic polar solvent, pharmaceutical synthetic intermediate
2. Physical and Chemical Properties
Physical Indicators
- Appearance: Colorless transparent viscous oily liquid
- Odor: Odorless, mild sweet taste
- Solubility: Fully miscible with water, ethanol, methanol, acetone and glycerin; slightly soluble in aromatic hydrocarbons; insoluble in aliphatic mineral oil
- Melting Point: 19–21 °C
- Boiling Point: 228–230 °C (760 mmHg)
- Density (20 °C): 1.015–1.020 g/cm3
- Refractive Index (20 °C): 1.444–1.446
- Flash Point: 130 °C
- Hygroscopicity: Strongly hygroscopic under high humidity air
- Aqueous Stability: Stable under neutral, weak acid and weak alkaline systems; no hydrolysis at room temperature
Chemical Characteristics
- Molecular Structure: Straight-chain saturated diol with two terminal hydroxyl groups, four carbon alkane backbone
- Core Functional Mechanism: Dual hydroxyl active groups for esterification, etherification and polymerization; core monomer for PBT plastic, PU elastomer and spandex fiber; low-molecular polyol humectant for water-based formulas
- Photostability: Stable under sealed dark storage, no obvious light-induced discoloration
- Thermal Stability: Stable below 180 °C; heating above 220 °C triggers dehydration to form tetrahydrofuran and unsaturated alcohols
- Chemical Compatibility: Compatible with most surfactants, resin monomers and cosmetic excipients; incompatible with strong oxidants and concentrated strong alkalis under high temperature
3. Main Application Fields
- Core Application: Polyester & Polyurethane Synthetic Monomer
Main raw material for PBT engineering plastic, polyurethane spandex fiber, PU elastomer and adhesive resins - Cosmetic Humectant Raw Material
Moisturizing and solubilizing additive for facial essence, shampoo, body lotion and water-based skincare products - Pharmaceutical Intermediate
Starting material for synthesizing anti-tumor, anti-inflammatory and circulatory system drug derivatives - Electronic & Coating Solvent
High-boiling polar solvent for water-based coatings, ink and electronic slurry to improve leveling performance - THF Synthetic Raw Material
