Ketone-terminated polyoxyalkylene compounds |
摘要 |
Mono-, di- and tri-ketones of polyoxyalkylene compounds prepared by a method whereby the terminal hydroxyl groups of polyoxyalkylene compounds are oxidized to ketone groups with an alkali metal or an alkaline earth metal hypochlorite oxidant in the presence of acetic acid are disclosed. These compounds are useful for preparing surface active agents or they may be reacted with amines to provide fuel additives.
