| Abstract: | Using potassium ion as template and in THF solution, 18crown6 was synthesized in 51.58 % yields by reaction of a mixture of triethylene glycol and dichlorotriethylenediether. Also, in dioxane solution, 18Crown6 was prepared in 64.4% yields by reaction of polyethylene glycol 270 and ptoluenesulfonyl chloride. The products were purified via 18crown6·CH 3NO 2 (1∶2) complex. The reaction conditions such as reaction time, molar ratio and state of potassium hydroxide were investigated. The product structure was determined by IR and m.p.. |
