Brown equation solution properties

Fullerene Ceo and aminosilica react in toluene or p-xylene solutions at heating with formation of brown adsorbent. Specific surface area of silica gel and Silasorb Amin containing fullerene Ceo after reaction of modification is increased a little in compared with the specific surface area of initial adsorbents. The values of C constant of BET equation for both adsorbents are practically the same. So the adsorption properties of these modified adsorbents are similar as well as the degree of modification by fullerene molecules. 

Among Other color reactions of quinones the color of their solutions in cone, sulfuric acid should be mentioned. 1,2-, 1,4-, and other isomeric quinones give distinctly different colors they change from yellow to green and blue (31). A simple detection scheme for quinones consists in bringing them into contact with an alkali, which leads to the formation of a brown to black color. Oxidative properties of quinones are also very important / -benzoquinone and 1,4-naphthoquinone liberate iodine from an acidified potassium iodide solution according to the equation...
