| 摘 要： | 用751G型分光光度计,以环已烷为惰性稀释溶剂,在紫外区间测定NMP与苯、甲苯、乙苯、对二甲苯、1,3,5-三甲苯的分子络合常数。NMP与芳烃存在着弱的化学作用,这种作用是NMP具有良好抽提芳烃能力的原因。

Molecular complexing constants of N-methylpyrrolidone with some aromatic hydrocarbons |
| |
| Abstract: | Using cyclohexane as inert diluent, molecular complexing constants for the N-methyl-pyrrolidone(NMP) with aromatics have been determined by UV spectrophotometer. These complexing constant provide an evidence that the weak chemical interaction between NMP and aromatics is the essential cause for NMP being an excellent extracting agent for aromatics in petroleum industry. |
