HYDROGEN SULFIDE CORROSION INHIBITORS BASED ON OXYETHYL PIPERAZINE DERIVATIVES

Abstract

The effect of the composition of the reaction mass of esterification of distilled tall oil with oxyethylated piperazine derivatives on the protective effect in hydrogen sulfide-containing media was studied. The reaction product is a mixture of complex mono- and diesters. Statistical processing of the results showed that the protective effect is mainly determined by the content of esterification products for one hydroxyl group. The maximum protective effect is achieved when the conversion of tall oil acids is not lower than 98 %.
