Abstract: This research work was focused on the effects of process parameters on mildsteel corrosion inhibition by ethyl ester of castor seed oil. This was motivated by the necessity of creating a formidable alternative (through castor oil generation) to deal with the menace of corrosion in our industries, and to assess the sensitive factors that affect the corrosion process. Standard methods were employed during the oil generation and its subsequent performing ability enhancement through acid esterification. Corrosion study conducted at varying reaction conditions of concentration, temperature and dosage showed that corrosion rate increases in the direction of increased process parameters; the least value of the weight loss (2.3146g) was recorded at the lowest concentration (10g/L), temperature (40oC) and Dosage (50% stroke), while the highest weight loss (37.1825g) was recorded at the highest concentration (20g/L), temperature (60oC) and Dosage (70% stroke). Corrosion rate was also found to increase with time, and was more established in cases of blank conditions when compared with those with inhibitors. Generally, the castor seed oil was found to have ability of inhibiting mildsteel corrosion substantively, and as such is recommended for advanced chemical engineering applications.
