Abstract

The oxotrinuclear compound [Ru2Co(O)(OOCCH3)6(C5H5N)3](ClO4) has been synthesized using RuCl3?nH2O at room temperature under oxygen atmospheric condition. The oxotrinuclear complex was characterized by FT-IR spectrophotometer and mass spectrometer with cold spray ionization (CSI) method. The FT-IR spectra of the resulted oxotrinuclear compound show has specific vibration at 692 cm-1. This absorption is related to M3O vibration (M= metal). CSI-mass spectra of the oxotrinuclear compound show that pyridine as ligand was fragmented in oxotrinuclear compound.

Abstract

A study on cyclopentylsilane reaction in tetrahydrofuran with 4-iodo thioanisol has been carried out using palladium as catalyst under argon atmosphere at room temperature. The results showed that the product was tris(4-thioanisyl)cyclopentylsilane (1) which was obtained from recrystallization using methanol with the yield 35%. The Compound (1) has a melting point of 91.5-92.0 oC. Analysis using GC-MS found m/z 466 with six equivalent protons and eight carbons peak obtained from 1H and 13C NMR.

Abstract

Flusilazole pesticide has been synthesized through coupling reaction of organosilica and aryl halide using palladium catalyst in basic condition under argon atmospherie in two reaction steps. The product was characterized using 1H and 13C NMR spectroscopy at 500 MHz and 125 MHz respectively.The results of this research showed that the high yield of colorless oil product was obtained up to 70%. 1H and 13C NMR spectra have six and eight peaks respectively, which indicate the structure of flusilazole.

Abstract

Separation of cellulose from sawdust using methanol and hydrocloric acid in various acid concentrations has been carried out. Cellulose from sawdust was characterized using FT-IR Spectroscopy and XRD difractometer. The cellulose was used as adsorbent for Mn2+ and Co2+ metal ions in aqueous medium. Adsorptions process was studied through variation of time interaction, concentration and separation desorption. FT-IR Spectrum shows that cellulose with 5% acid concentration has similarity with FT-IR cellulose standard. The XRD difractometer pattern of cellulose shows that cellulose has amorf structure. The adsorption rate constant of Mn2+ on cellulose from sawdust shows adsorption rate constant in cellulose is higher than in sawdust. Adsorption energy of Mn2+ metal ion in cellulose from sawdust was about 26.21 kJ/mol. The adsorption capacity of Mn2+ in cellulose is higher than in sawdust. The desorption of Mn2+ metal ion using H2O, Na-EDTA, Amonium acetic, and HCl shows that the adsorption mechanism of Mn2+ on cellulose and sawdust is dominated by chemical interaction.
