Modification of Sodium Lignosulfonate with a Synthetized Oligomer Based on Acrylamide and Citric Acid
The purpose of this work was to obtain a synthesized modifier by polycondensation of acrylamide and citric acid, followed by the creation of a composition with sodium lignosulfonate. During the synthesis, the ratios of the components of the starting substances, the temperature and time regime varied. The determination of the ratios of the main initial components of the synthesized modifier is confirmed by the method of mathematical modeling using the STATISTICA 12 software package. When obtaining a composition based on sodium lignosulfonate and a synthesized modifier, the ratio of components was 50:50 % by weight (for absolutely dry matter). The effectiveness of the obtained reagent was evaluated by the value of the surface tension of the aqueous solution of the samples under study with different concentrations. The possibility of using the obtained modified sodium lignosulfonate as a reagent for regulating the parameters of the drilling washing liquid is investigated.
