The scientific-technical journal

It is the scientific-technical journal in English in Ukraine discussing actual problems of chemistry and chemical technology. Compared with other chemical journals Ch&ChT is publishing materials of both theoretical and practical values in such fields as analytical, general organic, physical and inorganic chemistry; chemistry of high molecular compounds; materials science and engineering; chemical kinetics and catalysis; technology of inorganic substances; technology of organic synthesis products; chemical technology of processing of combustible minerals; processes and apparatus of chemical and food productions; biotechnology and ecology.

    Peculiarities of NMR1H and 13C spectra of benzoates and benzoylformates carbalkoxyl fragments
    (Publishing House of Lviv Polytechnic National University, 2010) Mizyuk, Volodymyr; Shibanov, Volodymyr
    Досліджено особливості ЯМР 1Н и 13С спектрів карбалкоксильного фрагменту алкілбензоатів і алкіл- бензоілформіатів. В спектрах ЯМР 13С приведені характеристичні величини хімічних зсувів трьох типів його атомів: карбоксильного, α- і β-вуглецевих атомів алкоксильних груп, а також протонів при цих атомах в спектрах ПМР. Проведено порівняння з аналогічними параметрами деяких карбалкоксилвмісних сполук загальної формули Y–COO–CН2–R. Peculiarities of NMR 1H and 13C spectra of benzoates and benzoylformates carbalkoxyl fragments have been studied. Characteristic values of chemical shifts of three types: carboxyl, α- and β-carbon atoms of alkoxyl groups have been presented in NMR 13C spectra. Characteristic values of protons attached to the mentioned atoms have been given in PMR spectra. Analogous parameters of some carbalkoxyl-containing compounds of general formula Y–COO–CH2–R have been presented for comparison.
