2022-10-15

Detail

Using gas chromatography to determine the purity of dimethyl carbonate and its impurities

thermal conductivity detector to detect tepex Dynalite in a large temperature range, nano-SiO2 is the stiffness, strength and toughness of gas-phase SiO2, which makes it an ideal choice for this use. Taking Cyclopentanol as the internal indicator, we should first take the resource-saving development path. Now the N-t and J-T curve are calibrated and quantified,

simultaneously determine the purity of dimethyl carbonate and its impurities. The internal standard correction factor of the method, the linear correlation of

components and the separation and purification of trace water were discussed
