COLOPHONY and It’s Derivatives as Corrosion Inhibitor Agent

Abstract

Colophony obtained from oleoresin, toll oil and wood stump sources from the Pine species. The dominant components of colophony are resin acids and abietic acid forms the primary resin acid. Colophony and derivatives as inhibitor agent of metallic surface corrosion and alloy dissolution in corrosive environments reviewed. The novel approach and basic chemical reactions of the colophony derivatives as a corrosion inhibitor given in detailed. Toxicity research approved that colophony and derivatives practically non-toxic component. This evidence has strengthened the reason why colophony is the escalated attention of industrial applications. Colophony is considered green oil because it is renewable, inexpensive, and environmentally friendly material. The ability of colophony, also named naval store, to improve the sealing properties of ships is well known feature. In the oil industry, colophony derivatives have rising interest of corrosion inhibitors thanks to their amphiphilic nature. Additionally, it could be utilized as petroleum dispersants. Colophony derivatives are renewable raw material which has enhanced solubility and ambient in nature. Besides, comparing to petroleum-based materials it has affordable price and low toxicity. Therefore, colophony and derivatives have advantageous as a unique raw material of advanced polymers applications compared to chemical based toxic corrosion inhibitors. A critical note that colophony and derivative does not causing water pollution in field such as maritime transportation.
