  • Crosslinking composition
    Patent number: 7381347
    Abstract: This invention relates to a crosslinking composition comprising a compound having the structure of Formula I: A?-NRA—RD where A? is a moiety derived from the group consisting of linear or cyclic ureas, cyanuric acid, substituted cyanuric acids, linear or cyclic amides, glycolurils, hydantoins, linear or cyclic carbamates and mixtures thereof, or a moiety comprising the structure: where RA is RD, hydrogen, an alkyl of 1 to 20 carbon atoms, or taken together with A? forms a cyclic compound; RD is —CHRC ORB, wherein RB is hydrogen, alkyl, aryl, aralkyl or an alkaryl having from 1 to about 24 carbon atoms and RC is an alkyl, halogenated alkyl, aryl, aralkyl, halogenated aralkyl, alkoxyalkyl or an alkaryl having from 1 to about 24 carbon atoms; A is a moiety derived from the group consisting of linear or cyclic ureas, cyanuric acid, substituted cyanuric acids, linear or cyclic amides, glycolurils, hydantoins, linear or cyclic carbamates and mixtures thereof; B is a residue of a poly(alkylaldehyde) with n al

  • Recovery of precious metal
    Patent number: 5028259
    Abstract: An improved process for recovery for precious metals such as gold and silver from aqueous cyanide solutions by contact with certain guanidine reagents. The guanidine reagents not only extract the precious metal but may provide advantages in selectivity of gold over other metals, such as tetra- and pentahydrocarbon substituted non-resin guanidine reagents and tri- and tetra-hydrocarbon substituted resin guanidine reagents.
