This paper, continue the study of acid hydrolysis of β – alkyl (C12H25/C18H37) polyethyleneoxy (= 3 – 20) propionitriles (I) with classical phase transfer catalyst (PTC) and a new generation.
The process is favoured by their presence in steadily increasing amounts for lower and higher values of micellar critical concentrations. The simultaneous presence of the cationic functional group and of the “homogeneous” polyethyleneoxy chains with variable degree of oligomerisation confirms the cumulated, favourable synergic effects.
