1)  copper catching regent
脱铜试剂
1.
The free α-amino was released from Nε-tert-butoxycarbonylation of L -lysine copper (Ⅱ)complex promoted by copper catching regent, and followed by Nα-9-fluorenylmethyloxycarbonylation catalysted by sodium carbonate with H2O-acetone as solvent to form Nα-9-fluorenylmethyloxycarbonyl-Nε-tert-butyloxycarbonyl-l-lysine (Fmoc-L -Lys (Boc)-OH).

2)  copper removal reagent
脱铜剂
1.
The effects of vacuum tightness, copper removal reagents selected and their amounts, melting temperature and removing duration on the removal rate were studied.
根据真空冶金原理,通过热力学分析,采用正交设计实验方法,研究了真空度、脱铜剂种类与用量、温度以及处理时间等对钢液去铜的影响·试验结果表明:真空条件下,加入脱铜剂尿素或氧化镁,钢液中的铜可以明显去除,能满足大部分钢种所要求的标准(w(Cu)<0 2%);比较两种不同的脱铜剂的脱铜效果发现,在相同条件下,尿素的脱铜效果明显好于氧化镁;随着脱铜剂用量增加、脱铜时间延长以及温度的提高,去铜率明显增加;当脱铜剂尿素用量为0 7%,脱铜处理时间40min,能够满足洁净钢质量的要求·在实验室研究的基础上,对工业化试验提出了初步的设想
