By combining 2 chloropyridine, 1,3,4 thiadiazole and acylamide, three toxophoric moieties seven 2 [ N (1 methoxycarbonyl)ethyl N acyl]amino 5 [(2 chloropyrid) 4 yl] 1,3,4 thiadiazoles(8) were synthesized in seven step...By combining 2 chloropyridine, 1,3,4 thiadiazole and acylamide, three toxophoric moieties seven 2 [ N (1 methoxycarbonyl)ethyl N acyl]amino 5 [(2 chloropyrid) 4 yl] 1,3,4 thiadiazoles(8) were synthesized in seven steps. The preliminary biological activity tests show that the title compounds reveal a certain plant growth regulating effect as well as fungicidal activity.展开更多
合成了一种新型的三唑硫酮类表面活性剂—3-己基-4-氨基-1,2,4-三唑-5-硫酮（HATT）,通过红外光谱和核磁共振氢谱及磁谱对其结构进行了表征,研究其在黄铜矿表面的吸附动力学和热力学。结果表明：黄铜矿吸附HATT优选的p H值为4~8,吸附量...合成了一种新型的三唑硫酮类表面活性剂—3-己基-4-氨基-1,2,4-三唑-5-硫酮（HATT）,通过红外光谱和核磁共振氢谱及磁谱对其结构进行了表征,研究其在黄铜矿表面的吸附动力学和热力学。结果表明：黄铜矿吸附HATT优选的p H值为4~8,吸附量随着温度的升高而增大;吸附过程符合准二级动力学方程,吸附活化能为13.06 k J/mol;HATT在黄铜矿表面的吸附等温线符合Langmuir模型,吸附焓变ΔH为71.52 k J/mol,熵变ΔS为348.7 J/（mol·K）,吸附自由能变ΔG为-28.95 k J/mol（298K）。HATT可能以单分子层化学吸附于黄铜矿表面,吸附为自发的吸热过程。FTIR光谱分析进一步证实HATT以化学方式吸附在黄铜矿的表面。浮选试验结果也表明,HATT是黄铜矿的优良捕收剂。展开更多
