1.Composite W-Cu oxide nanopowder was prepared by spray-drying and milling of ammonium metatungstate(AMT) and cupric nitrate.
采用铵、硝铜通过喷雾燥、焙烧、球磨工艺制氧化铜复合粉末。
2.The hexadecanol bischloroacetate was synthesized fastly with the technique of microwave irradiation with the anhydrous cupric sulfate as catalyst.
研究了在无水硫铜的催化下,利用微波辐射技术快速合成氯乙十六酯的方法及影响反应收率的因素。
3.According to the problems in dyes production,the role of cupric ion in coupling-cupric complexation was discussed,and the chelated forms of formazane reactive dyes were introduced.
