Synthesis methods and description for new derivatives associated with 8-hydroxyquinoline and their use as acidic corrosion inhibitors for steel and other alloys: a review

The field of corrosion has recently been considered a productive field for scientific research. With the increasing use of metals in several industrial fields, such as metal construction, the construction of arches and the automobile industry, the problem of corrosion is an important issue. To solve the corrosion problem of metal materials, several methods have been discovered to combat this phenomenon, such as process control, cathodic protection, organic and inorganic coatings. Nonetheless, the presentation of corrosion inhibitors, particularly organic inhibitors, stays the least expensive and simplest technique for the insurance of metals against consumption in acidic media. In this work, it was summed up the strategies for amalgamation and portrayal of newly innovative heterocyclic complexes from 8-hydroxyquinoline, their inhibition performances for M-steel, C40E steel and C35E steel in acidic conditions, for example, hydrochloric acid, sulfuric acid, etc.
