摘要：

Purpose - This paper seeks to evaluate the effect of natural menthols and their synthesised epoxy-allylmenthols as a non-toxic inhibitor on the corrosion of steel in HCl media at various temperatures. Design/methodology/approach - Epoxy-allylmenthols were synthesised and characterised. Gravimetric technique was used to measure the efficiency of corrosion inhibition. Findings - Modified allylmenthol (to epoxy-allylmenthol) exhibited a good inhibition. But its efficiency decreases with temperature. Research limitations/implications - The inhibition efficiency increases with the concentration of inhibitor to attain 74 percent at 0.8 g/l. Practical implications - The efficiency of menthol derivatives increases with the concentration but decreases with rise of temperature in the 303-328 K range. Natural inhibitor can be used in chemical cleaning and pickling processes. Originality/value - The originality of this work is to find a safe and cheap eco-friendly inhibitor from natural plants.
