Abstract The petroleum, petrochemical and chemical industries are totally dependent on the use of different iron alloys. The internal corrosion of oil pipelines, and other production, processing, storage and transport equipments is considered to be one of the most dangerous types of corrosion which couldn’t be seen by the human eye but we use many modern techniques to determine their internal corrosion rates. This is because the presence of organic and inorganic substances associated with oil production and distribution causing corrosion. The problems of corrosion are many and dangerous, while the most important of which is the oil spill as it resulted in loss of oil production and violation of international standards which may cause fires, explosions, loss of living beings, loss of production and equipments leading to a significant effect on the national economy. The utilizing of corrosion inhibitors is the most efficient approach to protect against internal metallic corrosion and to minimize the massive corrosion losses. Organic compounds like surfactants and polymers are used extensively for this purpose due to their low manufacturing price, ease of application, and physical characteristics. The most important kind of polymers used as corrosion inhibitors are Schiff base polymers. For this purpose, this thesis is concerned with synthesis of some novel Schiff base polymers and using them as corrosion inhibitors in sour petroleum |
