Животова Е. Н. Исследование физических состояний бинарных систем вода—оксиэтилированный глицерин со степенью полимеризации n = 5 и 25 при температурах ниже 273 К методом криомикроскопии [Електронний ресурс] / Е. Н. Животова, Л. Г. Кулешова, А. В. Зинченко, В. В. Чеканова // Доповiдi Національної академії наук України. - 2007. - № 4. - С. 78-84. - Режим доступу: http://nbuv.gov.ua/UJRN/dnanu_2007_4_16 Binary systems water - oxyethylated glycerol (OEG) with the polymerization degree n = 5 and 25 have been investigated by optical cryomicroscopy within the temperature range 173 - 273 K at a cooling rate of 30 K <$E roman min sup -1> and a warming rate of 5 K <$E roman min sup -1>. Cryomicrographs demonstrating the morphology of the crystalline and/or amorphous phases at different contents of OEG depending on temperature on cooling or warming are given. It has been shown that the systems with low (0 - 45 %) and medium (46 - 72 %) contents of OEG (n = 5) crystallize, and the high OEG (n = 5)-content systems (73 - 100 %) remain wholly amorphous. A similar situation is observed for the system water - OEG (n = 25) with insignificant differences in the concentration ranges. The fundamental distinction between the two systems consists in that the system water - OEG (n = 25) of the high OEG (n = 25) concentration (more than 77 %) forms an ordered structure in contrast to the system water - OEG (n = 5).
