Synthesis, Physicochemical and Antimicrobial Properties of 3-[3-[2-(Alkylamino)ethyI]-2-oxo-1-imidazolidiny1]-1propanesulfonic Acids

Abstract

Four kinds of 1-[2-(alkylamino)ethyl]-2-imidazolidinone [2] [alkyl: C12H25C, 141-129and C161433] were prepared by reactions of the corresponding 2-amino-2'-(alkylamino)diethylamine [1] with urea in good yields. Sodium salts of 3-[3-[2-(alkylamino)ethyl]-2-oxo-1imidazolidiny1]-1-propanesulfonic acids[3] were obtained from [2] and 1, 3-propanesultone with NaH as a catalyst.
The novel compounds obtained were purified through coloumns of anion- and cationexchange resins and identified by TLC, IR and elemental analyses.
Some surface-active and antimicrobial properties of the samples [3] were measured in aqueous solution. The results showed that these compounds were excellent as emulsifying, solubilizing and antimusty agents.
