SYNTHESIS BASED ON MONOCHLOROACETIC ACID AND APPLICATIONS OF PRODUCTS
Downloads
In order to obtain a new type of polydentate compounds that form stable complexes with metal ions in aqueous solutions, the
carboxymethylation reaction of peat (thiourea) with monochloroacetic acid was carried out (temperature range 50-95 С, reaction
time 2-7 hours). studied in alkaline media and by the esterification method. The composition and structure of the obtained
products were determined by IR spectroscopy. The inhibitory properties of the synthesized products of water inhibition in the
Navoi and Nukus regions with a hardness of 11-13 mgeq/l at a concentration of 7 mg/l with an efficiency of at least 90% have
been proven.
