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.

    Evaluating binol-aldehyde as a chiral derivatizing аgent for diamines
    (Publishing House of Lviv Polytechnic National University, 2015) Ravindranath, R.; So, S. M.; Chin, J.
    We have synthesized and tested a new binolaldehyde compound 1, against five diamine compounds. Using 1H NMR (400 MHz) spectroscopy, stable diasteriomeric imine complexes between 1 and five diamines were formed. Chemical shift nonequivalences (up to 0.058 ppm) were obtained for imines. Linear calibration plot was obtained for determining the enantiopurity of diamines. Синтезовано і досліджено нову бінолальдегідну сполуку 1 відносно п'яти діамінів. Використовуючи 1H ЯМР-спектроскопію (400 МГц), показано утворення стійких діастеріометричних імінних комплексів сполуки 1 і п'яти діамінів. Визначено нееквівалентність хімічного зсуву для імінів (до 0,058 ppm). Для визначення нантіочистоти діамінів побудовано лінійний калібрований графік.
