METHODS OF ANALYSIS OF SUBSTANCES SYNTHESIZED VIA ETHYLENE TELOMERIZATION REACTION

This scientific work explores the synthesis of isopropyl and isoamyl alcohols via telomerization of ethylene with methanol under high-pressure hermetic reactor conditions. Various analytical methods including IR spectroscopy, chromatographic-mass spectrometry, Raman spectroscopy, physicochemical, quantum chemical, and mathematical modeling were used to study and identify the structure and properties of the synthesized compounds. The analysis included the determination of boiling point, density, refractive index, and molecular refraction. IR spectra were obtained using the “INVENIO-S FTIR” spectrometer, and Raman spectra were recorded with the “InVia Raman BRAVO” device. Chromato-mass analysis was conducted using the Agilent MSD 5975C-GC7890A spectrometer. Quantum chemical calculations were performed via HyperChem Professional software, while mathematical modeling and experimental data processing were conducted using Maple 2018, applying the method of least squares. Density was determined using pycnometers, and refractive indices were measured by an Abbe refractometer.
