Product Description of Diethyl Carbonate CAS#105-58-8
Diethyl carbonate, or DEC, is an organic molecule carrying ethyl, ethoxy, carbonyl and ethoxycarbonyl functional groups. These functional moieties grant the substance high chemical reactivity, enabling its broad employment as a reactant for carbonylation, alkylation and carbethoxylation transformations.
DEC is a strongly hygroscopic, aprotic and eco-compatible solvent. It is frequently adopted for the processing and formulation of nitrocellulose, cellulose ethers and a variety of resin systems.
