Syntheses of tritium labelled nonionic detergents

Abstract Tritiated nonionic detergents, tri‐ and hexaoxyethylene glycol dodecyl ether, have been synthesized by condensation of triethylene glycol and dodecan‐2,3− 3 H, 3 H‐ol‐1, which was obtained by tritiation of 2‐dodecenol as the condensation product of decanal and malonic acid. They are found to be chemically, radiochemically and surface‐chemically pure enough for adsorption experiments by radiotracer method.
