    Abstract: Soluble copper(I)-amine complexes, particularly copper(I)-ammonia complexes and copper(I)-monoethanmolamine complexes, are useful injectable wood preservatives. Wood treated with the copper(I)-amine complexes contains less amines, and is less corrosive to metals, than woods treated with the prior art copper(II)-amine complexes. A method of preparing an aqueous wood preservative that includes soluble copper(I) complexes comprises reacting a solution comprising a copper(II)-amine complex with metallic copper to form a copper(I)-amine complex. One aspect of the invention comprises injecting a solution comprising a copper(I)-amine complex into wood and allowing the copper(I)-amine complex to precipitate within the wood.

    Abstract translation: 可溶性铜(I) - 胺络合物,特别是铜(I) - 氨络合物和铜(I) - 单乙胺盐酸胺络合物是有用的可注射木材防腐剂。 使用铜(I) - 胺络合物处理的木材比用现有技术的铜(II) - 胺络合物处理的木材更少,胺含量较少,对金属的腐蚀性较小。 制备包含可溶性铜(I)配合物的含水木材防腐剂的方法包括使包含铜(II) - 胺络合物的溶液与金属铜反应形成铜(I) - 胺络合物。 本发明的一个方面包括将包含铜(I) - 胺络合物的溶液注入木材中并允许铜(I) - 胺络合物在木材内沉淀。
