As an active compound, chloroacetic acid (MCAA) is an important organic fine chemical raw material widely used in pesticides (eliminating agents), medicines, dyes, oilfield chemicals (drilling fluids), paper chemicals, plastic additives (plastics). Stabilizers), textile auxiliaries, surfactants, electroplating, perfume flavors and other fields. Its greatest use is in the production of carboxymethyl cellulose (CMC), followed by the production of thioglycolic acid.
With the advancement and development of technology, new applications of chloroacetic acid have been gradually developed and the prospects are very broad. According to statistics, the main uses of chloroacetic acid in 2005 were: carboxymethyl cellulose (CMC) accounted for 33%, herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) and dimethoate accounted for 21%. In the application, thioglycolic acid accounted for 14%, amphoteric surfactant accounted for 12%, and cyano ester and malonate accounted for 11%. In Europe, CMC accounts for more than 40%, and in the United States, surfactants account for more than 20%.
There are several methods for the determination of chloroacetic acid: 1. Chemical titration; 2. Esterification gas chromatography. The above method is complicated in operation, not environmentally friendly, and the esterification method has a problem of conversion rate.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd., with the advancement of the times, developed high performance liquid chromatography for the determination of chloroacetic acid and impurities such as dichloroacetic acid, acetic acid and other impurities, the peak of dichloroacetic acid before chloroacetic acid, no coverage, Separated and the results are accurate. This column is a vast chromatographic, exclusive development, and is currently applying for patent protection.
