Industrial chloroacetic acid content of the side set by chemical titration analysis method. Monochloroacetic acid and dichloroacetic acid, respectively, with sodium hydroxide reaction, the two sodium chloride produced by the silver method for the total amount of chlorine. Dichloroacetic acid and sodium hydroxide continue to produce sodium oxalate potassium titanate titration, the dichloroacetic acid content. Monochloroacetic acid content is the total amount of chlorine minus the dichloroacetic acid.

 Chemical analysis method was used to compare the reasons for the difference. The method of esterification gas chromatography was used to determine the content of industrial chloroacetic acid and its impurities, and the operation was complicated. There was incomplete conversion rate, which was not conducive to the quality control of large-scale industrial production The

          Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., advancing with the times, to scientific development as a guide, relying on Xiangying Analysis Technology Research Institute, Institute of Chromatography, analysis and testing center, three scientific research units, successfully developed chloroacetic acid Direct injection analysis of packed column HHCL-II, determination of chloroacetic acid, acetic acid, dichloroacetic acid, over-test proved: HHCL-II chloroacetic acid dedicated packed column, direct injection method with better precision and accuracy, and safety Environmental protection, and can save time analysis, improve work efficiency, is conducive to large-scale production quality control.

 This column has the following characteristics:

1. Chloroacetic acid without esterification, direct injection analysis.

2. There is no need to transform the sample, save time, greatly improve the efficiency, is conducive to the industrialization of large-scale production quality control.

 3. This product, for my company exclusive research and development, is currently applying for patent protection.

 The vastness of chromatography provides a complete analytical method

The vast majority of chromatography, analytical technology leader

The vast number of chromatography, sales of not only products, more importantly, to help customers solve the problem, set up a bridge of spiritual communication
