Исследование физических состояний водных растворов оксиэтилированных производных ацетамида со степенью полимеризации n = 1 и n = 7 ÷ 8 методом оптической криомикроскопии
Ice crystal morphology in the binary systems water – oxyethylated acetamide (OEA) with polymerization degree n = 1 and 7÷8 is studied by optical cryomicroscopy over the temperature range of 173–273 K. Fine ice crystals are formed at low (20% w/w) concentrations of OEA (n = 1 and 7 ÷ 8). Dendrites...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Ice crystal morphology in the binary systems water – oxyethylated acetamide (OEA) with
polymerization degree n = 1 and 7÷8 is studied by optical cryomicroscopy over the temperature
range of 173–273 K. Fine ice crystals are formed at low (20% w/w) concentrations of OEA
(n = 1 and 7 ÷ 8). Dendrites of various orders are formed at medium concentrations (56%
w/w). The systems remain in a completely amorphous state at high concentrations (80% w/w).
One molecule of OEA (n = 1) is able to strongly bind 3 water molecules, and one molecule of
OEA (n = 7 ÷ 8) is able to strongly bind 7–8 water molecules. |
