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 NMR13C spectra of benzoic acid and saturated alkylbenzoates. I. Chemical shiftof benzoyl fragmentcarbon atoms
    (Publishing House of Lviv Polytechnic National University, 2008) Mizуuk, Volodymyr; Shibanov, Volodymyr; Kobrin, Lesya; Marshalok, Galyna; Elagin, Georgiy
    It has been shown that chemical shift of 5 types of carbon nuclei of benzoyl fragment in saturated alkylbenzoates depends upon alkyl radical degree of branching near alfa-carbon atom of alkoxyl group. Typical values of chemical shifts of five nuclei for primary, secondary and tertiary alkylbenzoates have been admitted. Показано, що хімічні зсуви 5 типів ядер вуглецю бензоїльного фрагменту в насичених алкілбензоатах закономірно залежать від ступеню розгалуження алкільного радикалу біля альфа-вуглецевого атому алкоксильної групи. Прийнято типові значення хімічних зсувів цих п'яти типів ядер для первинних, вторинних та третинних алкілбензоатів.
