METHOD OF PREPARING SALT CORROSION INHIBITOR Russian patent published in 2000 - IPC

Abstract RU 2146244 C1

FIELD: method of preparing salt corrosion inhibitor. SUBSTANCE: method comprises reacting chloroalkanes resulting from hydrochlorination of higher fatty alcohol fraction with ethylene diamine in aqueous medium during heating operation, hydrocarbon chain of chloroalkanes containing 12-14 carbon atoms, and process is carried out at temperature of 150-160 C and pressure of 0.57-0.65 MPa. Amount of water is 5-15% based on weight of initial products, preferably 10%. The resulting inhibitor has high protecting effect and has bactericidal activity with respect to corrosion aggressive sulfate reducing bacteria. EFFECT: more efficient preparation method. 2 cl, 6 ex, 3 tbl
