surface-active substances

The review of methods of industrial equipment corrosion prevention is presented. Application of technological means using chemical reagents and surface-active substances is considered, namely dehydration and desalting of hydrocarbon products of deposits by surface-active substances – so called demulsifiers. Corrosion inhibitors and neutralizing agents for protection of condensation-refrigeration equipment and overheads of atmospheric columns are examined. The amount of reagents to be used and the process conditions were determined.

The synthesis of functional derivatives of epoxystearic acid methyl ester by oxirane ring opening and transesterification of ester group has been described. Some novel surface-active and peroxide-containing compounds have been obtained. Major features of the process have been investigated and main characteristics have been determined.
