Propylene Carbonate
1. Basic Product Information
Product Name: Propylene Carbonate
CAS Number: 108-32-7
Molecular Formula: C4H6O3
Molecular Weight: 102.09
Synonyms: 4-Methyl-1,3-dioxolan-2-one, PC
Product Category: Polar aprotic high-boiling solvent, lithium battery electrolyte solvent, chemical synthesis raw material, cosmetic solubilizer
2. Physical and Chemical Properties
Physical Indicators
- Appearance: Colorless transparent oily liquid
- Odor: Slight faint ester odor
- Solubility: Miscible with water, ethanol, methanol, acetone, ethyl acetate, toluene; dissolves inorganic salts, polymers and polar organic compounds strongly
- Boiling Point: 242 °C
- Melting Point: -49 °C
- Density (20 °C): 1.205 g/cm3
- Refractive Index: 1.419–1.421
- Hygroscopicity: Moderately hygroscopic, absorbs water vapor in open air
- Aqueous Stability: Stable under neutral and weak acidic conditions; hydrolyzes slowly under strong alkaline heating to generate propylene glycol and carbonate
Chemical Characteristics
- Molecular Structure: Five-membered cyclic carbonate ester with methyl substituent
- Core Performance: High dielectric constant polar solvent, excellent dissolving capacity for lithium salts, resins, dyes and additives
- Photostability: Good light stability under sealed condition; no obvious discoloration under daily light
- Thermal Stability: Stable below 220 °C; high-temperature pyrolysis releases CO? and propylene oxide
- Chemical Compatibility: Compatible with most organic solvents, lithium salts and nonionic surfactants; incompatible with strong alkaline solutions, strong reducing agents and strong oxidants
3. Main Application Fields
- Core Application: Lithium-ion Battery Electrolyte Solvent
High-dielectric main solvent for lithium battery electrolyte, dissolves lithium hexafluorophosphate and other lithium salts, improves battery ionic conductivity - Industrial Polar Cleaning & Synthetic Solvent
Solvent for polymer synthesis, resin extraction, plastic degreasing and electronic component cleaning - Cosmetic & Personal Care Raw Material
Mild solubilizer and humectant for essence, sunscreen, facial cream, improves solubility of oil-soluble active ingredients - Pharmaceutical & Fine Chemical Intermediate
Reaction medium for heterocyclic synthesis, carrier for drug topical formulations - Gas Separation Agent
CO? absorbent for industrial waste gas recovery
4. Platform Category & Product Group Selection Guide
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Organic Intermediates
Reason: High-boiling cyclic carbonate industrial solvent widely used in new energy, fine chemical and daily chemical industries
2) English Product Group Dropdown Options
Recommended Selection: Basic Organic Chemicals
Do NOT select Pharmaceutical Chemicals; it is universal industrial solvent rather than exclusive human drug API
3. Standard Foreign Trade Packaging Specification
