Abstract:

Salified higher aliphatic amides (C₁₂H₂₅/C₁₈H₃₇) have been reported in the literature together with classical surface-active components, as products that potentiate their sanitation colloidal competences. This work brings to attention two variants for the obtention of some salified (HCOOH; CH₃COOH) β-alkyl (C₁₂H₂₅/C₁₈C₃₇) polyethyleneoxy (n = 3-20) propionamides, the first through the nucleophilic addition under basic catalysis of the hydroxyl functional group in higher polyethoxylated alcohols to the acrylamide monomer, followed by stoichiometric salification with HCOOH and/or CH₃COOH, the second through the partial acid hydrolysis of β-alkyl (C₁₂H₂₅ /C₁₈C₃₇) polyethyleneoxy (n =3-20) propionitriles to the corresponding propionamides, followed by stoichiometric salification with HCOOH and/or CH₃COOH. In this work the dependence of the processing yields on the operating parameters (temperature, duration, catalysts etc.) is investigated.

Keywords:

Salified polyethoxylated propionamides, food sanitation, propionitriles, micellar catalysis, phase-transfer catalysis
