“…where n is an integer between 0 and 7, R1 is an unbranched aliphatic chain (such as alkyl or alkenyl) with 12-22 carbon atoms, and R2 is a short aliphatic chain (such as alkyl or alkenyl group) that usually contains 1-4 carbon atoms. The simplest FFA is ODA, n = 0, R1 = C 18 H 37 , which is also the most widespread in the energy sector 4,15,[28][29][30][31][32] and has the longest history of utilization. It belongs to the primary aliphatic amines with a saturated carbon chain.…”

Film forming amines (FFA) are corrosion inhibitors added to power plant water. The major concern associated with their application is the thermal stability in the high temperature power plant water medium, along with the risk of decomposition into low molecular weight organic acids that can cause corrosive damages in the water/steam cycle. However, there is still a lack of sufficient data on the thermal stability of FFA corrosion inhibitors. This paper presents a comprehensive critical review and state‐of‐the‐art assessment of the results obtained from studying the thermolysis of FFA corrosion inhibitors in power plant water/steam cycle conditions, highlighting the relevance for practical application and research needs. Temperature, exposure time, initial concentration, and alkalizing agents were identified as key factors influencing the thermal stability of FFA in high temperature power plant water. Organic acids are found in concentrations harmless to metal tubes. Advanced scientific background information and additional research are required on this topic.
