Oxidation of Peat to Organic Acids

Milling of Pharmaceutical Solids

“…Crystals of pure substances have internal weaknesses due to missing atoms or ions in their lattice structures and flaws arising from mechanical or thermal stress (6). If an ideal crystal were pressed with an increasing force, the force would be distributed uniformly through its structure until the crystal disintegrated into its individual units.…”

“…There does not seem to be a quantitative relationship of grindability to hardness (6). A grindability index has not been generally accepted for materials other than coal, because of the wide variety of grinding equipment that may be used and the dissimilar physicochemical properties of materials.…”

Metal-Catalyzed Oxidation of Polyethylene

“…Oxidation of peat with air and an alkaline permanganate catalyst at 150°C. converts up to 22% of the carbon to water-soluble polycarboxylic acids (13).…”
