The novel water-soluble compounds are the ethyl ether and the N,N-dialkyl(C 1 to C 4 )aminoethyl ethers of β-cyclodextrin (β-CD). n The process for the preparation of these ethers is performed by reacting β-CD with an etherifying agent in a basic liquid reaction medium. The reaction medium contains an alkali-metal hydroxide, water and at least one water-miscible organic solvent (for example, dimethoxyethane or isopropanol). |
