Abstract

Schiff base compound was a product between carbonyl and primary amine compounds in acidic conditions. Based on several studies, the compound had activity as a corrosion inhibitor. Schiff base compounds were synthesized from vanillin and aniline using natural acid catalysts from Belimbing Wuluh (Averrhoa Blimbi L.) with volume variations 0; 0.25; 0.5; and 1 mL and grinded for 10 minutes. The synthesized compound was characterized by its physical properties. Further characterization included a UV-Vis spectrophotometer, FTIR and GC-MS. The corrosion inhibition efficiency on metals was carried out in HCl 1M. Synthesized compounds were yellowish-white solids, slightly soluble in water, and had a melting point at 149-151°C. The yield with volume variations 0; 0.25; 0.5; and 1 mL in a row were 96.84; 93.81; 92.45 and 89.69%. The synthesized compound had wavelengths 283-284 and 325-330 nm. This compound had an imine bond (-C=N-) with wavenumber 1584.909 – 1585.974 cm−1. The product with a 0 mL catalyst was characterized by GC-MS and showed a peak with retention time 24.173 minutes and m/z 227. It had a similarity with the molecular weight of the 2-methoxy-4- ((phenylamino)methyl)phenol compound. The inhibition efficiency of these compounds was 39.38 to 77.40%.
