Disclosed are salts comprising triaminocyclopropenium cations and various anions, and ionic liquids comprising the salts. Also disclosed are intermediates and methods of preparing the salts. The ionic liquids are useful as, for example, solvents and electrolytes, and for gas storage.
Russell-Jones theory for the dissociative volatilization process and a standard approach based on the Arrhenius model. The values of the parameters characterizing the thermal properties of alkanaminium hexachlorostannates, i.e. temperatures of the thermal effects, and the thermochemical and kinetic constants of thermolysis, depend on the number, length and structure of the alkyl substituent. The essential
摘要 热分析方法(DTA、TG 和 DTG)用于研究具有通式 [(CnH2n+1)pNH4-p]2SnCl6(其中 n = 1–4 和 p = 2–4)的无支链复合盐的热行为和其他几种环状和开链支链脂肪族链烷胺六氯锡酸盐。这些化合物的热解离通常可以使用等式来概括,其中 A 表示烷基(a = 0 和 s = 1 表示季铵盐,a = 1 和 s = 0 表示其他研究的化合物)。具有简单结构的衍生物的热解发生在一个步骤中并导致它们的完全挥发。其他化合物的分解,通常具有复杂的结构,伴随着副反应。实验 TG 曲线用于检查热解的热力学和动力学。热解离焓基于范特霍夫方程进行评估。导出的值与可用的文献数据一起用于确定盐的形成焓和晶格能。后者的数量也使用 Kapustinskii-Yatsimirskii 公式进行了检查。使用Jacobs 和Russell-Jones 解离挥发过程理论和基于Arrhenius
Superparamagnetic Fe(OH)<sub>3</sub>@Fe<sub>3</sub>O<sub>4</sub> Nanoparticles: An Efficient and Recoverable Catalyst for Tandem Oxidative Amidation of Alcohols with Amine Hydrochloride Salts
nanoparticles were successfully prepared and characterized. This magnetic nanocomposite was employed as an efficient, reusable, and environmentally benign heterogeneous catalyst for the direct amidation of alcohols with aminehydrochloridesalts. Several derivatives of primary, secondary and tertiary amides were synthesized in moderate to good yields in the presence of this catalytic system. The catalyst was
磁性Fe(OH)3 @Fe 3 O 4纳米粒子的制备和表征成功。该磁性纳米复合材料用作将醇与胺盐酸盐直接酰胺化的有效,可重复使用且对环境无害的多相催化剂。在该催化体系的存在下,以中等至良好的产率合成了伯,仲和叔酰胺的几种衍生物。该催化剂已成功回收利用,最多可重复使用六次,而不会显着降低其催化活性。
Oxidative amidation by Cu(<scp>ii</scp>)–guanidine acetic acid immobilized on magnetized sawdust with eggshell as a natural base
Copper(II)–guanidine acetic acidcomplex was immobilized on the surface of magnetized raw waste sawdust (SD) as an abundant natural biopolymer and employed as an efficient and recoverable catalyst in oxidative amidation reaction, while waste eggshell (ES) powder was used as a low-cost solid base. The magnetic raw catalyst was fully characterized using FTIR, XRD, SEM, EDX, TGA, and VSM. A variety of
The present invention is directed to novel chromane derivatives substituted in the 3-position by a substituted amino moiety and substituted on the aromatic ring with one or two substituents. The novel chromane derivatives have useful CNS properties. ##STR1##
