Mixture of imidazoline was synthesized from a mixture of corn oil acids and polyethylene polyamine in a molar ratio 2:1. Propyl-, butyl-, pentyl-, hexyl-, heptyl-, octyl- amine complexes of sulfated oleic acid were prepared. The mixtures were prepared from 20% solution of imidazoline and amine complexes at a weight ratio of 1:1. The obtained compositions were tested as corrosion inhibitors of H2S corrosion in a biphasic medium of kerosene-water (in a ratio of 1: 9) containing 3% NaCl and 500 mg/l H2S.
