Cas No. :105-58-8
Diethyl Carbonate(DEC)
Property and application
Molecular formula: C5H10O3
Composition Structure: .jpg)
It is a colorless ,transparent liquid with a molecular weight of 118.13 and density of 0.97g/cm3. It has a boiling point of 126.8℃ and a melting point of -43oC.It is a high quality solvent and textile auxiliary agent. It has found wide applications as ethylating and carbonylating reagents in organic synthesis. It is also used as solvents of nitro-cotton, cellulose ether, synthetic resin and natural resin in the textile printing and dyeing industry. Diethyl carbonate can make dyeing uniformity and increase fading quality against sunshine; it is a nice solvent of polyamide, polyacrylonitrile and diphenol resin and it can improve feel of the textiles and anti-crease quality in the synthetic fiber industry. It is used as paint remover in the paint industry; in the plastic process it is the solvent if plasticizer or can be used as solvent of plasticizer directly or can be used as plasticizer directly. It is used to be prepare the electrolyte in the capacitor battery and lithium battery. In the pharmaceutical industry it is the basis ingredient of hard and is used to synthesize intermediate Phenobarbital etc. Thus it has an extensive market-developing prospect.
Specification :( It conforms to the Quality System Standard: ISO9001:2000)
