Va. Kucherenko et al., OXIDATION OF NATURAL COAL WITH ACETYL NITRATE AS A FIRST STAGE OF PREPARATION OF CARBON ADSORBENTS AND HUMIC ACIDS, Russian journal of applied chemistry, 69(9), 1996, pp. 1306-1310
Interaction of coal with acetyl nitrate at room temperature is studied
by determination of variations in the yield and characteristics of so
lid products (oxidized coals), followed by ESR, infrared spectroscopy,
and derivatography. The process is considered as a first step of prep
aration of carbon adsorbents in the chemical activation mode and of hu
mic acids by alkaline hydrolysis.
