Methyl acetate is a by-product of the production of glacial acetic acid. The total ester content in methyl acetate is about 80%. According to the qualitative results of chromatography, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. conducted a gas chromatography analysis test to determine the content of methyl acetate. The test situation is as follows. GC-790 gas chromatograph (thermal conductivity detector) Stationary phase: 10% polyethylene adipate/401 organic support packed column: stainless steel tube with a length of 2m and an inner diameter of 4mm Vaporization chamber temperature: 150℃ Detection chamber temperature : 140℃Column temperature: 130℃Bridge flow: 200mA Hydrogen carrier gas flow rate: 75mL/min Injection volume: 2μL 2. Qualitative method Use retention time to directly compare with known substances for qualitative determination. The qualitative results for the methyl acetate sample are shown in the figure.
