Corrosion is an unavoidable fact in everyday life but always receive attention to control due to its technical, economical, and esthetical importance. Corrosion inhibitors are one of the most widely used and economically viable methods protecting metals and alloys against corrosion. Typical corrosion inhibitors are bio-toxic organic compounds, which have serious issue on toxicity. Considering the toxicity of the inhibitors, there is a tremendous interest in searching for an eco-friendly, and non-toxic green corrosion inhibitor. This chapter briefly discusses the importance and different methods of corrosion inhibitors with a particular emphasis given to the discussion on the different characteristic feature of the green corrosion inhibitors reported in the literature as a comparative view of organic inhibitors.

Polyethylene terephthalate waste (PET) was depolymerized by thiodiglycol into thioglycolyzed product. The product was characterized by FTIR and 1 HNMR spectroscopy and the thermal properties (TGA, DTA) showed that the prepared compound was thermally stable until 250˚C. The efficiency of the prepared corrosion inhibitor for carbon steel was measured by using acid media (0.1 HCl) as corrosive environment and the inhibitor concentration was (0, 10, 20, 30, 40 and 50 ppm). The electrochemical technique used Tafel plot to measure the efficiency of inhibitor. Factors effect on the rate of corrosion like temperature (298, 308, 318, 328 K) and concentration (10,20,30,40, 50 ppm) of inhibitor were studied. From the obtained results many factors were calculated that determined the efficiency of the inhibitor like corrosion rate, charge transfer resistance and inhibitor efficiency. It was observed that the corrosion rate and charge transfer of the carbon steel for the inhibitor increase with increase of temperature and decrease with increase of the inhibitor concentration in the same temperature. The results showed that the inhibitor had high inhibition in reducing the corrosion rate. The inhibition efficiency (% IE) reached 97.1% for the 40 ppm concentration at 308 K.

“…Various chemicals have been used for protection against corrosion of mild steel or metals [7][8][9][10][11][12][13][14][15][16][17][18][19][20]. For polymeric inhibitors [11], the use of polyvinylimidazoles [12], polyvinylpyrolidone [13][14], polyvinylpyridine [15][16][17][18][19][20] has been widely examined. Poly(4-vinylpyridine), P(4-VP) has been used as corrosion inhibitor of mild steel and iron in HCl [15], of copper in 3 M HNO 3 [16], of Zinc in 1 M H 2 SO 4 [17], of iron in 1 M H 2 SO 4 [18][19] and of Cu60-Zn40 in 0.5 M HNO 3 [20].…”

In this work, the oligomer of 4-vinylpyridine designated as O(4-VP) was synthesized by hydrogen peroxide initiated chain growth polymerization and characterized in terms of molecular weight and structure by matrix assisted laser desorption ionization time of flight mass spectroscopy (MALDI-TOF MS). The oligomer was tested as corrosion inhibitor of mild steel in brine solution saturated with carbon dioxide, with the main purpose to investigate the effect of inhibitor concentrations and temperatures on the inhibition activity defined in terms of corrosion rate and percent of protection. The inhibition tests were carried out using the methods of weight loss (WL) and linear polarization (LP). Characterization using MALDI-TOF MS revealed that the oligomer has the mass (m/z) in the range 200-2400, which corresponds to chain length of 2-22 repeating units. The results of corrosion rate measurements show that the corrosion rate with the use of oligomer is significantly lower than that without inhibitor, demonstrating that the oligomer functioned as effective corrosion inhibitor, while the 4-vinyl pyridine monomer was found to promote the corrosion. It was also found that the protection by the oligomer increased with increasing temperature and it was predicted the oligomer was chemically adsorbed by the surface of the metal. Keywords: oligomer 4-vinylpyridine; corrosion inhibitor; CO 2 corrosion; MALDI-TOF MS ABSTRAK Dalam penelitian ini, oligomer 4-vinilpiridin, O(4-VP), disintesis menggunakan inisiator hidrogen peroksida untuk pertumbuhan rantai polimer dan dikarakterisasi berat molekul dan struktur molekulnya menggunakan matrix assisted laser desorpsion ionization time of flight mass spectroscopy (MALDI-TOF MS). Oligomer kemudian diuji sebagai inhibitor korosi baja ringan dalam larutan air garam yang jenuh dengan gas karbon dioksida, dengan tujuan utama untuk menyelidiki efek dari konsentrasi inhibitor dan suhu pada aktivitas inhibisi yang dinyatakan dalam bentuk laju korosi dan persen proteksi. Tes inhibisi dilakukan dengan menggunakan metode kehilangan berat (WL), dan polarisasi linier (LP). Karakterisasi menggunakan MALDI-TOF MS
