Synthesis of Tris(4-Methoxyphenyl)Phenylsilane using phenylsilane and 4-Iodo anisole catalyzed by palladium complex
" Sintesis Tris(4-Metoksifenil)Fenilsilan Menggunakan Fenilsilan dan 4-Iodida Anisol dengan Katalis Senyawa Kompleks Paladium. Sintesis tris(4-metoksifenil)fenilsilan melalui reaksi kopling antara fenilsilan dan 4-iodida anisol menggunakan senyawa paladium tersier tributilfosfin sebagai katalis telah dilakukan berdasarkan penentuan senyawa basa, pelarut, dan waktu reaksi kopling. Hasil penelitian menunjukkan bahwa senyawa tris(4-metoksifenil)fenilsilan dapat disintesis menghasilkan persentase produk maksimum pada penggunaan senyawa 1,4-diazabisiko[2,2,2]oktan (DABCO) sebagai basa, tetrahidrofuran sebagai pelarut, dan waktu reaksi kopling selama 5 hari. Persentase tertinggi produk senyawa tris(4-metoksifenil)fenilsilan adalah ... "

Characterization and Utilization of Calcium Oxide (CaO) Thermally Decomposed from Fish Bones as a Catalyst in the Production of Biodiesel from Waste Cooking Oil
" Thermal decomposition of fish bones to obtain calcium oxide (CaO) was conducted at various temperatures of 400, 500, 800, 900, 1000, and 1100 °C. The calcium oxide was then characterized using X-ray diffractometer, FTIR spectrophotometer, and SEM analysis. The calcium oxide obtained from the decomposition at 1000 °C was then used as a catalyst in the production of biodiesel from waste cooking oil. Diffraction pattern of the calcium oxide produced from decomposition at 1000 °C ... "

Production of adipic acid from mixtures of cyclohexanol-cyclohexanone using polyoxometalate catalysts
" Adipic acid production through catalytic conversion of cyclohexanol-cyclohexanone using polyoxometalate H5[a-BW12O40] and H4[a-SiW12O40] as catalysts was carried out systematically. Polyoxometalates H5[a-BW12O40] and H4[a-SiW12O40] were synthesized using an inorganic synthesis method and were characterized using Fourier transform infrared spectroscopy (FTIR). Adipic acid was formed from conversion of cyclohexanol-cyclohexanone and was characterized by using melting point measurement, identification of functional group using FTIR spectrophotometer, analysis of gas chromatography-mass spectrometry (GC-MS), and 1H and 13C NMR (nuclear magnetic ...
