An attempt was made to determine the relationship of chemical properties of reagents to their flotation activity. The relationship of the destruction of paramagnetic centers of the coal after absorption of the reagents to the dipole moment of the reagents was determined for aliphatic and aromatic compounds as well as compounds having two polar groups. H was determined that this destruction of paramagnetic centers is a good indicator of flotation activity. Flotation activities of various groups of compounds were determined: naphthenes, aliphatic acids, alcohols, esters, ketones, and 1,3-dioxan. Of all the compounds tested, 1,3-dioxan was found to have the best flotation activity. (JMT)
