A series of long chain alkoxymethyl-15-C-5 3 have been synthesized by the cyclization of alkoxymethyl oligoethylene glycol 2. The surface tension, CMCs and γ~C~M~C of the aqueous solution of alkoxymethyl crown compounds and 2 were determined at 25℃, 35℃, 45℃. The results showed that CMCs reduced with the increase of the number of carbon atoms n, compound 2 and 3, in which the number of carbon atoms in the side chain is more than 8 , may form micelle in aqueous solution.
