According to GB/T 3728-2023, the inspection items and corresponding test methods or standard basis specified in the standard include: appearance (GB/T 3728-2023/5.2), chromaticity (platinum cobalt color code) (GB/T 3143), ethyl acetate content (GB/T 3728-2023/5.4), ethanol content (GB/T 3728-2023/5.4), moisture (GB/T 3728-2023/5.5), acidity (calculated as acetic acid) (GB/T 3728-2023/5.6), density (GB/T 3728-2023/5.7), evaporation residue (GB/T 3728-2023/5.8), benzene derivatives (benzene, toluene, ethylbenzene, xylene) (GB/T 3728-2023/5.4).
Among them, the determination of ethyl acetate, ethanol, and benzene derivatives mainly uses gas chromatography; The moisture content was determined using the Karl Fischer method; The acidity is determined by titration method; Density measurement is carried out using the densitometer method.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts 6% cyanopropyl phenyl/94% dimethyl polysiloxane/to establish a method suitable for exploring and optimizing the preparation process of ethyl acetate, which can quickly and accurately determine the content of ethyl acetate.
