Abstract

Schiff bases can be synthesized by reacting Vanillin and p-aminoacetophenone using a natural acid catalyst such as lime juice (Citrus aurantifolia.) with the grinding method. The purposes of this study were to determine the characterization. The yield of synthesized compounds calculated and also determined the physical properties such as color and melting point. The product also characterized using NaOH reaction. Further characterization was carried out using FTIR and 1H-NMR. The synthesized compound is a yellow solid, slightly soluble in water, and has a melting point of 160-162 °C. The Mass obtained is 1,9459 g, with a percentage yield of 94,45%. The compound 1- {4 - [(4-hydroxy-3-methoxy-benzylidene) -amino] -phenyl) -etanone reacts with NaOH to form a bright yellow color. This compound has an imine bond (-C = N-), which showed in the wavenumber 1583 cm-1. 1H-NMR characterization showed a typical chemical shifting of HC = N- at 8,5 ppm. The inhibition efficiency of these compounds ranged from 23,11-86,16%.
