A method for the quantitative determination of ethylene oxide adducts in their aqueous solutions or dispersions

  • Published:
Journal of the American Oil Chemists' Society

Summary

A method for quantitative determination of ethylene oxide adducts is described. By precipitation in hydrochloric acid solution with a known quantity of ferrocyanic acid, filtration, and titration with zinc sulfate, the consumption of ferrocyanic acid can be determined. From the results a m.d. of less than 8% was calculated, the corresponding figure for adducts containing more than 9 ethylene oxide units does not surpass 5%. The reaction takes place on the ethylene oxide chain in the compound. To precipitate an adduct containing 6 units ethylene oxide approximately one mole of ferrocyanic acid is necessary.
