The gelling ability of a series of dialkoxy-9,10-anthraquinone derivatives has been investigated in a number of organic solvents at different concentrations. The most efficient systems were found to be formed from the 2,3-dialkoxy (OCnH2n + 1) derivatives with n = 8–11 (compounds 9–11, 14–15). In ethanol, a gel is formed with 2,3-di-n-decyloxyanthraquinone (11) at a concentration of ca. 10–2M (0.65 g/100 g) at 30 °C. The gel-to-sol transition temperatures were determined in ethanol, isopropanol and n-heptane as a function of gelling agent concentration. The gel-to-sol transition enthalpies (23–51 kJ mol–1) were found to be in agreement with recent results obtained for other gel forming systems.
一系列二烷氧基-9,10-蒽醌衍生物在不同浓度的有机溶剂中进行了凝胶能力的研究。最有效的体系是由2,3-二烷氧基(OCnH2n + 1)衍生物形成的,其中n = 8–11(化合物9–11, 14–15)。在乙醇中,2,3-二-n-十二烷氧基蒽醌(11)在约10–2M的浓度(0.65 g/100 g)下于30°C形成凝胶。研究了醇-凝胶转变温度在乙醇、异丙醇和正庚烷中作为凝胶剂浓度的函数。发现凝胶-溶液转变的焓变(23–51 kJ mol–1)与近期获得的其他凝胶形成体系的结果一致。
