PREPARATION OF SOME PURE POLYOXYETHYLENEGLYCOL ETHERS. PART I

Abstract

The Williamson ether synthesis has been applied to the preparation of polyoxyethyleneglycol mono- and di-ethers. These were obtained by reacting the mixed potassium salts of hexaoxyethyleneglycol with alkyl or aryl halides. Hexaoxyethyleneglycol monoethers of the type R_•O(CH₂CH_2•O)₆H, (R = n-C₁₀H₂₁, n-C₁₂H₂₅, n-C₁₄H₂₉, and p-iso-C_8•H_17•C₆H_4•O_•CH₂CH₂) and diethers of the type R_•O(CH_2•CH_2•O)_6•R, (R = n-C₁₀H₂₁, n-C₁₂H₂₅, and n-C₁₄H₂₉) have been prepared in pure state and some of their properties determined.
