摘要

The goal of the given activity is study and development of the possibility of supercritical fluid as specific reactant. We report on the first evidence of 100% reactivity of some oxides (as powders or pattern) with supercritical isopropanol. We developed two autoclave methods for performance of experiments: in sealed ampoules and in opened glass containers. The transition in supercritical state has been conducted by increasing of reaction temperature and the inner pressure respectively. The standard experiments have been carried out at temperatures and pressures, which were higher (on 50-70°C and more) than critical ones of isopropanol to go out of the field of instability, which usually occurred in the field of phase transition. After the reaction the solid phase has been studied by X-ray analysis, DTA, TGA and the liquid one-by GC and GC-MS. We were the first to notice heterogeneous chemical reaction, the reactants of which were supercritical fluid and metal oxide.
