SYNERGISTICALLY ACTIVE BASE SYNTHESIS FOR CORROSION INHIBITORS
Keywords:heterocycles, imidazoline derivatives, carboxylic acid ammonium salts, fatty acids, ethylenediamine, synergistically active base, corrosion inhibition
The temperature dependence and catalytic method of synthesis of imidazoline derivatives have been compared. It has been found that fatty acids and ethylenediamine, which are part of cottonseed oil, are achieved by the formation of a 1:1 ratio and monoamides and imidazoline derivatives acting at temperatures 190 and 240Сt. Compositions have been prepared by adding the vacuum distillation cubic residue of methanol, formaldehyde, and mono-ethanolamine into the composition of the products obtained, and it has been determined that with an increase in the amount of active base, the degree of corrosion protection also increases. The degree of corrosion protection is high when the amount of synergistically effective additives methanol and formaldehyde was up to 10 g, while the amount of MECRVD was 5 g. As keeping the samples under conditions with a dose of hydrochloric acid of 15 and 23%, the inhibitor concentration was 99.6 and 99.01%, respectively, when the concentration of the inhibitor was 10 g/l.
