Title (EN) METHOD OF PREPARING COPPER-CONTAINING WOOD PRESERVING COMPOSITIONS
(FR) PROCÉDÉ DE PRÉPARATION DE COMPOSITIONS DE PRÉSERVATION DU BOIS CONTENANT DU CUIVRE
Abstract:
(EN) The present invention relates to a method for producing copper ammonia solutions by reacting a cuprous oxide with ammonia, carbon dioxide and an oxidant. The resulting copper-containing solution can then be used to formulate a variety of wood preserving products.
(FR) La présente invention concerne un procédé de production de solutions cuivre ammoniac consistant à faire réagir un oxyde de cuivre avec de l'ammoniac, du dioxyde de carbone et un oxydant. La solution contenant du cuivre ainsi obtenue peut ensuite être utilisée pour formuler une variété de produits de préservation du bois.
