CAS:930-22-3丨BUTADIENE MONOXIDE

The compound corresponding to CAS No. 930-22-3 is Butadiene monoxide, also known as 3,4-epoxy-1-butene, with a molecular formula of C₄H₆O and a molecular weight of approximately 70.09 g/mol.
Butadiene monoxide is a colorless, transparent to slightly yellow liquid at room temperature. It has a melting point of -135°C, boiling point of 65–67°C, and density of 0.87 g/mL at 25°C. This compound is highly flammable, with a flash point of approximately -50°C and refractive index (n²⁰/D) of 1.417. Butadiene monoxide is insoluble in water but soluble in organic solvents such as methanol and ethanol.

Uses:

Butadiene monoxide serves as an important fine chemical intermediate for synthesizing various high-value products:
Medicine and pesticides: Used as a synthetic raw material for chiral compounds and drug intermediates.
Materials science: Employed to prepare functional polymer materials and novel flame retardants.
Chemical fiber industry: Can be further converted into basic chemicals like 1,4-butanediol and tetrahydrofuran.

Method of Preparation:
- The main method of preparing epoxybutane is through the oxidation of butadiene.
- Butadiene is reacted with hydrogen peroxide and oxidized in the presence of a catalyst to produce butyl epoxide.
