Demulsifying capacities of hydroxyethyl acyl derivatives of glycerol and ethanolamines

Summary

  1. 1.

    The authors have determined the demulsifying capacities of hydroxyethyl acyl derivatives of glycerol and mono- and triethanolamine containing different numbers of ethylene oxide groups.

  2. 2.

    It is shown that the number of hydrophobic and hydrophilic groups in the surfactant molecule has an effect on the demulsifying capacity and optimal content of ethylene oxide groups.

  3. 3.

    It has been established that an increase in the reagent's demulsifying capacity is obtained by increasing the number of hydrophobic groups in the molecule; an increase in the number of hydrophilic groups has a lesser effect. In contrast to this, an increase in the number of hydrophilic groups has a more marked effect on the reduction of the ethylene oxide content in the molecule of the reagent with maximum demulsifying capacity.

  4. 4.

    The presence of an amide group in the molecule of a hydroxyethyl reagent (hydroxyethyl amide of an aliphatic acid) has a very beneficial effect on the demulsifying capacity and the reduction of the ethylene oxide content.
