PROPERTIES OF 3-(VINYLOXY)HEX-4-EN-1-YNE AS A CORROSION INHIBITOR IN RECIRCULATING WATER AND HEATING SYSTEMS

Abstract

This article analyzes the potential of 3-(vinyloxy)hex-4-en-1-yne for protecting metal surfaces against corrosion in recirculating water systems and heating systems. Organic corrosion inhibitors are distinguished by their ability to form a protective adsorption layer on the metal surface. A review of the literature shows that acetylene alcohols and their vinyloxy derivatives, especially in neutral and mildly alkaline media, can reduce the corrosion rate on steel surfaces. In recirculating water systems, corrosion is associated with dissolved oxygen, chloride and sulfate ions, hardness salts, deposits, and biofouling, whereas in closed heating systems one of the main factors is dissolved oxygen. The vinyloxy fragment, the unsaturated hydrocarbon chain, and the electron-rich centers in the molecule of 3-(vinyloxy)hex-4-en-1-yne may enhance its ability to adsorb onto the metal surface and form a protective layer. Therefore, this compound is considered promising either as a component of water-treatment reagents or as an independent organic inhibitor.
