Determination of industrial glyoxal aqueous solution by capillary column
Determination of industrial glyoxal aqueous solution by capillary column Detailed information:

Stationary phase: polyethylene glycol 20M
Specification: 30m*0.32mm*0.25um
Model: HH-WAX
Application: HG/T 5275-2017 Industrial Glyoxal Solutions

Glyoxal has a variety of production methods, and its purification targets are also different. At present, more is used to produce glyoxal by gas phase oxidation of ethylene glycol. At this time, the main impurity to be removed is formaldehyde. The process of purifying the aqueous solution of glyoxal by solvent extraction was emphasized, and compared with other purification methods.
