Pengaruh Daya Iradiasi Gelombang Mikro Terhadap Profil Kromatografi Lapis Tipis pada Sintesis Metilorto-Metoksisinamat

This study was conducted to compare some of microwave power, 120 Watt, 280 Watt and 400 Watt against the TLC profile on the synthesis of orthocoumaric acid derivative compounds, namely methyl ortho-methoxycinnamate. Methylation was carried out on the OH groups of carboxylic acid and phenolic groups from o-coumaric acid with dimethyl sulfate as a methylating agent. The material is dissolved in acetone and the alkaline reagent K2CO3 is used. sampling was carried out every 30 seconds on each power. As a result, complete reactions on 120 Watt, 280 Watt and 400 Watt were achieved at the 25th, 12th and 10th sampling times, respectively. Based on the results analysis using FT-IR spectrophotometer of the compound, this synthesis succeeded in producing new compounds. So it can be concluded that the higher the power used, the faster the reaction time.
