1. Basic Info
Name: Succinic anhydride
Alias: Dihydrofuran-2,5-dione, Butanedioic anhydride
CAS No.: 108-30-5
Molecular Formula: C4H4O3
Molecular Weight: 100.07
2. Physical & Chemical Properties
Physical Properties
- Appearance: White flaky crystalline solid with slight irritating odor
- Solubility: Soluble in hot water, ethanol, acetone, chloroform; slightly soluble in cold water; insoluble in petroleum ether
- Melting Point: 119.5–120.5 ℃
- Boiling Point: 261 ℃
- Density (20℃): 1.503 g/cm3
- Sublimation: Sublimes easily at low pressure and heating
- Hygroscopy: Absorbs water vapor in air and gradually hydrolyzes into succinic acid
- Volatility: Volatile with steam at high temperature
Chemical Properties
- Cyclic anhydride structure: Five-membered anhydride ring, high reactivity
- Hydrolysis reaction: Reacts with water to generate succinic acid; faster under heating or acid/alkali catalysis
- Esterification: Reacts with monohydric alcohols to form succinic acid monoester and diester
- Amidation: Condenses with primary/secondary amines to generate succinimide or amide derivatives
- Ring-opening addition: Reacts with phenols, thiols, hydroxyl groups to introduce succinyl functional groups
- Thermal stability: Stable below melting point; decomposes slightly above 280 ℃
- Compatibility: Compatible with most inert organic solvents; reacts violently with strong bases, water, alcohols, amines
