中文摘要: 采用价格低廉的石化工业副产品癸烯混合物为原料合成新型铜萃取剂5-癸基水杨醛肟。适宜的合成条件为：(1)甲酰化反应，n(癸基酚)∶n(镁) ∶n(多聚甲醛)=1∶0.67∶2.8，反应时间5h；(2)肟化反应，n(癸基酚)∶n(盐酸羟胺)=1∶1，反应时间1h。产物结构经MS，NMR和EA分析确定，GC测定产物纯度大于99.0%，产率75.9%。与M5640和M5774萃取性能测试对比表明，研制的萃取剂具有较高的铜负载能力(6.36g/L)，较好的铜铁选择性(β[Cu/Fe]?=1340)，萃取与反萃平衡时间短，单极铜萃取率>98.0%，单极铜反萃率>90.0%。

Abstract:A novel copper extractant 5-decylsalicylaldoxime is synthesized with the use of a cheap mixture by-product, 5-decylsalicylaldoxime, from the petrochemical industry. The optimal condition is, n(decylphenol):n(magnesium):n(paraformaldehyde)=1:0.65:2.8, reaction time 5h for the formylation reaction and n(decylphenol):n(hydroxylamine hydrochloride)=1:1, reaction time 1h for the oximation reaction. Under this condition, the yield of the desired product reaches to 75.9% (based on decylphenol) with 99.0% purity (determined by GC). The structure is elucidated by MS, NMR and EA analysis. It is indicated by the comparison with the M5640 and M5774 that the extraction performance of the product is of high copper load capability (6.36 g/L), good copper selectivity over iron (β[Cu/Fe]?=1340), the extracting and stripping balance time are short, the extracting rate is more than 98% and the stripping extracting rate is more than90% through only one stage.
