In this work, we report carbon-silicon bond formation in thiophene, assisted with alkylated silylchloride. The formylation reaction of silylated thiophene has been discussed and achieved 61% overall yield of reactions. The compounds obtained are characterized quantitatively and qualitatively by using elemental analysis, FT-IR spectroscopy, UV/Visible spectroscopy, and proton NMR spectroscopy. This research work will boost chemists to make the carbon-silicon bond and utilize them in various applications. Journal of Engineering Science 11(1), 2020, 101-105

The advanced oxidation of Congo red (CR) and Nigrosine (NI) using the combined action of dimethyl dioxirane as an oxidising agent is described in this study. The effects of several parameters, such as the concentration of the oxidising agent, the initial dye concentration, and the pH, have been investigated. At room temperature, the oxidising agent dimethyl dioxirane was employed to test the degradation of CR and NI dyes. On the degradation efficiency of CR and NI, pH’s effects, oxidising agent, and initial dye concentration were examined. The absorbance of CR and NI dyes before and after degradation was measured using UV-visible spectroscopy. The functional group existing in the dyes before and after degradation was determined using FT-IR spectroscopy.

Photoacoustic FT-IR spectroscopy was used to quantify kaolinite in binary mixtures with KBr and silica, with the use of a linear relationship between the reciprocals of photoacoustic intensity and kaolinite concentration. The method is valid for both dilute and concentrated mixtures; an average error of 12% was obtained for kaolinite concentrations ranging from 15 to 80%. The technique thus compares favorably with more common approaches that require low analyte concentrations. It is concluded that quantitative photoacoustic infrared spectroscopy is feasible provided that the magnitude of the product of thermal diffusion length and absorption coefficient is taken into account.
