The effect of aqueous brown onion peel extract on the corrosion process of carbon steel in 1 mol L-1 HCl was examined The electrochem. results, including the displacement of the corrosion potential and the inhibitory action in both anodic and cathodic polarization curves showed that the examined extract acted as mixed-type inhibitor. The results of the electrochem. impedance measurements showed that the Rct values increased in the presence of inhibitor reaching 94% of inhibition efficiency in the presence of 300 mg L-1 of the extract The inhibition efficiency of C-steel in 1 mol L-1 HCl increased as the temperature increased and the apparent activation energy (Ea) of C-steel dissolution decreased in the presence of the extract, which suggest a strong chemisorptive bond between the components present in the onion extract and the metal surface. The extract anal. showed few volatile compounds with 3(2H)-Furanone, 2-hexyl-5-methyl- as the major volatile compound and a nitrogenous base (5-octadecyl-pyrimidine-2,4,6-trione) which may play an important role in the inhibition process. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7SDS of cas: 5444-75-7).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.SDS of cas: 5444-75-7
