Synthesis of dipeptide benzoylalanylglycine methyl ester and corrosion inhibitor evaluation by Tafel equation

Corrosion is one of the major problems in petroleum mining and processing industry. The pipelines used to transport crude oil from reservoir to the processing installation were made from carbon steel that is susceptible towards corrosion. One of the best methods to prevent corrosion that occurred at...
