Determination of Purity and Components in Dimethyl Carbonate by Gas Chromatography

A simple, fast, and reliable gas chromatographic method for the determination of purity and components in dimethyl carbonate (DMC) has been developed. The sample was seperated with a HP-Wax polar capillary column and detected with a TCD detector using cyclopentanol as the internal standard. The quan...

Summary:A simple, fast, and reliable gas chromatographic method for the determination of purity and components in dimethyl carbonate (DMC) has been developed. The sample was seperated with a HP-Wax polar capillary column and detected with a TCD detector using cyclopentanol as the internal standard. The quantitative determination of the components and trace water in the sample were carried out with the relative standard deviations less than 4.6% and the absolute errors less than 0.04%. The correction factors and linear relationship were obtained.
