What is Diethyl carbonate CAS 105-58-8？

Diethyl carbonate is a kind of colorless and transparent liquid with slightly pungent odor with CAS 105-58-8. Insoluble in water, soluble in organic solvents such as alcohol and ether.Anhydrous ethanol reacts with phosgene to form ethyl chloroformate, which continues to react with ethanol to form diethyl carbonate. It is then washed and distilled to obtain the finished product. Raw material consumption quota: ethanol 1450kg/t, phosgene 2250kg/t.

Diethyl carbonate (DEC) CAS 105-58-8 molecule contains ethyl, ethoxy, carbonyl and carbonyloxy groups, which are chemically active, and are commonly used carbonacylation, alkylation and carbonylation reagents.

Application：

1 Organic synthesis intermediates

It is mainly used as a solvent for nitrocellulose, cellulose ether, synthetic resin and natural resin, and an intermediate for pesticide pyrethroid and drug phenobarbital. It is used in the instrumentation industry to make fixing paint, and is used in the sealing and fixing of the cathode of the electron tube.

2 Lithium-ion battery electrolyte

Due to its high energy density and low volatility, diethyl carbonate is a promising candidate for use as an electrolyte in lithium-ion batteries.

3 Fixing varnish

Used in the sealing and fixing of electron tube cathodes in the instrumentation industry.
