Key product of Tengzhou Zhongke Spectral Analysis Instrument Co., Ltd. - ortho cyanobenzyl chloride analytical gas chromatograph

Method principle】Cyano benzyl chloride is a white crystal with a pungent odor,It is obtained by chlorination of ortho cyanotoluene,Can dissolve in organic solvents such as ethanol, dichloromethane, chloroform, etc,And insoluble in water,Mainly used for producing fluorescent whitening agentsERImportant raw materials,It needs to be measured in industrial production,In order to accurately control the feeding process,Reduce consumption,Improve product quality. Quantitative detection of o-cyanobenzyl chloride by gas chromatography using naphthalene as an internal standard,The retention time of the peak is short,The separation method is simple and easy to implement,The accuracy of the measurement results is high.
