Application
1. Solvent for nitrocellulose; manufacture of radio tubes; fixing rare earths to cathode elements.
2. Diethyl carbonate is an important intermediate in organic synthesis. It is mainly used as solvent of nitrocellulose, cellulose ether, synthetic resin and natural resin, intermediate of pyrethroid and phenobarbital. In the instrument industry, it is used to prepare the fixing paint and to seal and fix the cathode of the electronic tube.
