dianisalacetone compounds. The purity test was carried out on both the synthesized compounds by melting point test and thin layer chromatography then the structure was identified by IR spectrophotometry. The results of the synthesis were tested for antioxidant activity by the DPPH method. Based Academia.edu is a platform for academics to share research papers.TLC, then the compounds were characterized by, IR, 1H-NMR, 13C-NMR spectroscopy and GC-MS. Based on the result of analysis, dibenzalacetone and dianisalacetone compounds can be synthesized and give yields 62% and 93%. It can be concluded that the yield of dianisalacetone was higher thanHow to fight a crosswalk ticket
