Dependence of the composition of the mixture of total acid hydrolysis of β-nonylphenoxypolyethyleneoxy (n=3-16) propionitriles contaminated with 2% PEG 9 on the degree oligomerization of the polyoxyethylene chain (n), molar ratio dodecylbenzenesulphonic acid/β-nonylphenoxy polyethyleneoxy (n=3-16) propionitrile [NF(EO) n PN] 0.5/1, processing time 60 minute, temperature 80°C, molar ratio [water/NF(EO) n PN] 2/1, without phase-transfer catalyst.
