Figure 21

Graphical representation of the steps of exhaustive acid hydrolysis (PTC 2 /PTC 3 ), “sandwich model” under phase-transfer catalysis (PTC) of β-nonylphenoxypolyethyleneoxy (n=3-20) propionitriles [NF(EO) n PN)] to β-nonylphenoxypolyethyleneoxy (n=3-20) propionic acids [NF(EO) n PC)] Mathematical correlation of the experimental data enabled the generalization of a particular casuistry through mathematical relationships (linear, exponential, logarithmic and/or polynomial) correlation coefficients R2 in the range 0.9-1. Thus are confirmed the reproducibility of the values recorded and the accuracy of the interpretations made.
