Abstract

Telah dilakukan sintesis tris-(4-thioanisil)oktilsilan (1) melalui reaksi kopling antara oktilsilan dengan 4-iodidathioanisol. Reaksi dilakukan menggunakan katalis paladium dalam kondisi atmosfir inert menggunakan pelarut tetrahidrofuran. Senyawa (1) diperoleh dalam bentuk cairan tak berwarna dengan rendemen 20% mempunyai tujuh puncak 1H NMR, tigabelas puncak 13C NMR dan memiliki nilai m/z 510.Synthesis of tris-(4-thioanisyl)octylsilane (1) by coupling reaction between octylsilane and 4-iodo thioanisole has been done. Reaction was carried out using palladium as catalyst in inert condition and tetrahydrofuran as solvent. Compound (1) was obtained in colorless oil with the yield 20% has seven peaks of 1H NMR, thirteen peaks of 13C NMR and m/z 501.

Abstract

Telah dilakukan preparasi kalsium oksida dari tulang ayam dengan proses dekomposisi selama 3 jam pada variasi temperatur 400oC, 500oC, 700oC, 800oC, 900oC, 1000oC, 1100oC. Karakterisasi CaO hasil dekomposisi dengan XRD menunjukkan pola difraksi CaO pada temperatur dekomposisi 1100°C mendekati difraksi CaO standar (JCPDS) yang memiliki nilai 2?: 34,2º, 37,3º, 58,3º, 64,1º dan 67,3º dengan struktur kristalin. Pita serapan pada spectra FTIR Ca-O dari tulang ayam terlihat pada daerah 354,90 cm-1 yang menunjukkan adanya vibrasi Ca-O hasil dekomposisi, diperkuat dengan munculnya puncak pada gelombang 870 cm-1. Kemudian persentase CaO di dalam sampel dikonfirmasi dengan data EDX yang menunjukkan persentase sebesar 56,28%.Preparation of calcium oxide from chicken bones has been carried out systematically by decomposition for 3 hours at various temperatures i.e. 400, 500, 700, 800, 900, 1000 and 1100 oC. Formation of calcium oxide from decomposition process was characterized using X-Ray diffractometer. The results showed that XRD pattern of materials obtained from decomposition of chicken bones at 1100 oC which has a values of 2?: 32.2º, 37.5º, 58.3º, and 64.1º with a crystalline structure is similar with XRD pattern of calcium oxide standard from Joint Committee on Powder Diffraction Standards (JCPDS) . The absorption bands in the FTIR spectra of the Ca-O shown at 354.90 cm-1 region indicated the presence of Ca-O vibration, reinforced by the emergence of a peak at 870 cm-1. The percentage of 56.28% of CaO in the sample was confirmed by EDX data.

Abstract

Telah dilakukan tripel arilasi senyawa organosilika primer dengan beberapa aril iodida menggunakan katalis paladium dengan teknik reaksi kopling. Reaksi dilakukan dalam kondisi atmosfir argon dengan 4-diazabicyclo[2,2,2]octane sebagai basa dalam pelarut tetrahidrofuran. Senyawa hasil sintesis yakni tris(5-metil-2-thiopen)fenil silan (1), tris(4-N,N-dimetil anilin) fenil silan (2), dan tris(2-thiopen)fenil silan (3) berhasil disintesis walaupun memilki persentase yield yang rendah yakni 27% untuk senyawa (1), 23% untuk senyawa (2) dan 17% untuk senyawa (3)The triple arylation between primary organosilica and several aryl iodides have been carried out using palladium catalyst by coupling reaction. Reaction was conducted in argon atmospheric with 4-diazabicyclo[2,2,2]octane as a base in tetrahydrofuran as a solvent. The products, which were tris(5-metil-2-thiopen)fenil silan (1), tris(4-N,N-dimetil anilin) fenil silan (2), and tris(2-thiopen)fenil silan (3), were successfully synthesized although with low yield. The yields of (1), (2), and (3) are 27%, 23%, and 17% respectively.
