Procedure

5 Equivalents of dimethylcarbonate were added to a solution of 53 mg 18-crown-6 in 1 ml diethylether at 25° C. A solid complex was formed immediately. The precipitated crystals were filtered off at atmospheric pressure. The crystals contained 81% of the starting amount of 18-crown-6. A melting point range of 39°-54° C. was observed.
