Synthesis and Evaluation of Some Local Anticorrosion (anti-rust) Additives for Some Petroleum Products

UNDER the effect of the work, lubricating oils absorb moisture from the weather and/or from the oxidation reaction on the metal surface. Therefore, anti-rust and anti-corrosion additives must be used. Rust and corrosion inhibitors, which form a barrier film on the substrate surface reducing the corrosion rate. The inhibitors also adsorb on the metal surface forming a film protecting the part from the attack of oxygen, water and other chemically active substances. The object of this study is to synthesis and evaluate of zinc octoat & barium octoat as anti-rust, anti-corrosion additives. They were applied with oils&greases. Synthesized additives were added with different ratio to semi synthetic cutting oil and sodium grease blends. Many trials have been carried out to obtain the optimum dose. Formulated blends were tested according to IP standard test no. 125.
