Abstract:
In the preparation of (poly)cyclic polyethers by a cyclic Williamson synthesis, the improvement of contacting the reactants in a hindered (C. sub. 4 -C. sub. 14) alkanol. For example, bis-chloroethyl ether and the disodium salt of tetraethylene glycol are contacted in t-butanol to produce the cyclic polyether ##STR1## in high yields.
