Synthesis and characterization of citral-methylanthranilate schiff base, relationship between synthesis time and some physical properties

Abstract

Citral-Methylanthranilate Schiff base was synthesized by the reaction of citral and methylanthranilate in simple condensation technique. The synthesis was carried out at temperature (90 ± 5) °C and various synthesis times of 15 minutes, 30 minutes, 1 hour, 2 hours, 3 hours, and 4 hours. Product of Citral-Methylanthranilate Schiff base spreads color in bright red to black brown as the synthesis times increases. The results of the refractive index of synthesis time variation were 1.541 to 1.561. The values of density at various synthesis times were 1.017 to 1.042 g/mL. The results of the specific gravity of synthesis time variation were 1.026 to 1.050. Analysis with GC-MS was performed to prove that citral-methylanthranilate was actually formed and resulted in the peaks at 18.023 and 19.123 minutes.
