Reduction of cuprous cyanide with hydrogen in a liquid medium
专利汇可以提供Reduction of cuprous cyanide with hydrogen in a liquid medium专利检索，专利查询，专利分析的服务。并且Cuprous cyanide is dispersed in a high boiling hydrocarbon oil nonreactive with hydrogen, copper or HCN, such as a paraffin mineral oil, and hydrogen is passed through at temperatures from 190* C. to temperatures at or a little below the boiling point of the oil. With an oil boiling above 325* C., suitable temperatures are from a little below 300* C. to approximately 325* C. Hydrogen is passed through at a rate and for a time to produce a substantial excess, for example at least 50 percent excess, and the cuprous cyanide is reduced almost quantitatively to a very pure copper powder. After reduction is complete, the copper powder is separated from the oil, the last traces of oil being removed by known means, such as solvent washing, or removed when the copper is melted. The excess hydrogen carries with it HCN formed in the reduction, and the two are separated and reused.，下面是Reduction of cuprous cyanide with hydrogen in a liquid medium专利的具体信息内容。
