HYDROCHLORIC ACID CORROSION INHIBITOR Russian patent published in 1997 - IPC

Abstract RU 2096525 C1

FIELD: oil production. SUBSTANCE: hydrochloric acid corrosion solution is essentially mixture of hydrochloric aminoparaffins prepared by amination of C10-C26 chloroparaffins containing 15-46 wt % organic chlorine at 120-160 C with ethylene diamine in organic chlorine to diamine equimolar ratio to attain residual organic chlorine content of not higher than 3 wt %. Use of corrosion inhibitor makes it possible to prevent more effectively corrosion of metals in hydrochloric acid. EFFECT: improved properties of the corrosion inhibitor.
