International Classification:

B03D 1/14
B03D 1/016
C02F 1/56

US Classification:

209166000, 209167000, 208390000, 208391000, 208425000

Abstract:

Modified resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These modified resins are especially useful as froth flotation depressants in the beneficiation of many types of materials (e.g., mineral and metal ores), including the beneficiation of impure coal comprising clay impurities, as well as in the separation of valuable bitumen from solid contaminants such as sand. The modified resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water. The modified resins comprise a base resin that is modified with a coupling agent, which is highly selective for binding to solid contaminants and especially siliceous materials such as sand or clay.

Abstract:

Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants in the separation of bitumen from sand and/or clay or in the beneficiation of clay (e.g., kaolin clay) from an impure clay-containing ore. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water.

Assignee:

Georgia-Pacific Resins, Inc. - Atlanta GA

International Classification:

C08G 6378
C08G 6387

US Classification:

528205

Abstract:

The present invention is directed to the formation of phenol alkylation polymers which release negligible phenol and formaldehyde emissions. The phenol aralkylation polymers of the present invention are derived from a phenolic monomer, at least one styrene derivative and an aryl diolefin. In addition to the phenolic monomer, styrene derivative and aryl diolefin. In addition to the introduced to produce a product with particular properties.

International Classification:

C08G 5900

US Classification:

528 86

Abstract:

The present invention is directed to the formation of phenol alkylation polymers which release negligible phenol and formaldehyde emissions. The phenol aralkylation polymers of the present invention are derived from a phenolic monomer having at least three free reactive aromatic ring positions, at least one styrene derivative and an aryl diolefin. In addition to the phenolic monomer, styrene derivative and aryl diolefin, other reactants may be introduced to produce a product with particular properties.
