Diethyl carbonate
Properties and Uses
Colorless transparent liquid, molecular weight: 118.13, density 0.97g / cm3, a boiling point of 126.8 ℃, a melting point of -43 ℃, is an excellent solvent and Auxiliaries, widely used in organic synthesis ethyl agent, a carbonylation agent, carbonyl ethoxylated agent for nitrocellulose, cellulose ether, synthetic resin and solvent natural resin. In the textile printing and dyeing, and diethyl ester of carbon allows uniform distribution of dyeing, enhance the light fading properties: Solvent aspect is a good solvent of polyamide, polyacrylonitrile, bisphenol resin, etc., in the synthetic fiber industry to improve the feel of the fabric, improved wrinkle resistance; used as a solvent in the paint stripping industry; as plasticizers in plastics processing solvent or directly as a plasticizer; the capacitor battery, lithium battery industry for the preparation of the electrolyte; in medicine as pine ointment base ingredient, synthetic intermediates phenobarbital, has a wide range of market development prospects.
