Versuchsvorschrift

According to this invention, 22 grams of ethylene carbonate, 11 grams of 2-decanone and 0.565 grams of CsCl were placed in a 100 ml round-bottomed flask which was fitted with a thermometer, distillation head and a cold trap. The flask was heated in an oil bath (with magnetic stirring) at about 150° C. to about 175° C. for about 8 hours. Analysis of the reaction mixture by gas chromatography showed that 15-Crown-5 and 18-Crown-6 were formed.
