Kucherenko V. Coal insertion compounds with alkali metal hydroxides and oxidants containing nitronium and nitrosonium cations.

The thesis is devoted to determination of general regularities of forming coal insertion compounds (CIC) under intercalations of coals with metal hydroxides МОН (M=Li, Na, K, Rb, Cs) and oxidizing agents containing nitronium and nitrozonium cations (HNO3, HNO3-Ac2O, HNO3-(CF3CO)2O, NO2BF4, NOHSO4, NOBF4, NaNO2-H2SO4). Alterations of spatial and molecular structure as well as paramagnetic characteristics of coal during intercalation have been studied under varying reagent nature and coal rank. The main regularities of thermolysis and hydrolysis have been obtained for CICs with intercalated particles of different nature. The generalized scheme of intercalation involving formation of coal cationic fragments, penetration of acid anions forming ion pairs, chemical modification of coal framework as reactions of substitutions, oxidations and oxydestructions. CICs have been shown to yield high-porous solids under known processes of active carbon preparations. It has been found possibility of surface area development under CIC preparation followed by high rate heating.
