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(CH2CH2•O)6H, (R = n-C10H21, n-C12H25, n-C14H29, and p-iso-C8•H17•C6H4•O•CH2CH2) and diethers of the type R•O(CH2•CH2•O)6•R, (R = n-C10H21, n-C12H25, and n-C14H29) have been prepared in pure state and some of their properties determined.
