A 2-phase system is prepd. by mixing o-xylene or iso-BuCOMe, contg. a nonionic surfactant in some cases, with a soln. of a-cyclodextrin or b-cyclodextrin in water contg. NaOH and NaBH4, and epichlorohydrin is added to the system to give water swellable, water insol. beads comprising cyclodextrin derivs. capable of forming inclusion complexes (e.g., useful for sepg. isomers and racemic mixts.) or stabilizing compds. against oxidn., enzymic decompn., etc. [on SciFinder (R)]
