| dc.description.abstract | The production of Butyl Decanoate from Butanol and decanoic acid has been
carried out through an esterification reaction using lipase enzyme as a catalyst and microwave radiation. The parameters studied in this study were reaction time with variations of 0,5, 1, 3, 5, and 7 minutes and microwave power with variations of 10, 20, 30, 40, and 50%. Determination of the conversion of Butyl Decanoate was carried out by alkalimetric titration. The obtained Butyl Decanoate was analyzed for changes in its functional groups using FT-IR. The maximum conversion of Butyl Decanoate of 97.52% ± 0.20% was obtained for the reaction time parameters obtained at conditions of 1 minute, 20% microwave power, 1:2 mole ratio, and 1% catalyst weight. While for the microwave power parameters obtained at conditions of 20% microwave power, 1 minute time, 1:2 mole ratio, and 1% catalyst weight of 97.54% ± 0.21%. The formation of an ester group from the resulting butyl decanoate is marked by a peak at a wave number of 1714 cm-1 indicating the stretching vibration of the group (C = O) which indicates the presence of esters and is supported by the formation of stretching vibrations -C-O-C- ester at a wave number of 1028 cm-1. Based on GC-MS, the ion peak at m/z 228 indicates the molecular weight of butyl decanoate and the base peak 56 so that it can be concluded that there has been a butanol substitution process for the H atom contained in the carboxylic acid group of decanoic acid. | en_US |
