Abstract

Prezenta inventie se refera la un procedeu de obtinere a nonilfenolului prin achilarea fenolului cu nonena în prezenta schimbarilor de ioni constînd din copolimeri stirendivinilbenzenici sulfonati utilizati drept catalizator de reactie la temperatura de 80....120 degree C caracterizat prin aceea ca în scopul realizarii unui grad de conversie ridicat de peste 88% a nonenei într-un timp de reactie scurt reactia are loc într-o singura structura monoporoasa cu continut de 10....15% umiditate si capacitate de schimb de 4.7....4,9 mval/g asigurînd selectivitate marita la obtinerea nonilfenolului, purificarea produsului obtinut efectuîndu-se în mod uzual prin distilare la presiune redusa si în prezenta de 0,1% stabilizator hiposfit de sodiu.The present invention relates to a process for obtaining nonylphenol by acylation of phenol with nonene in the presence of ion changes consisting of styrenedivinylbenzene sulfonate copolymers used as a reaction catalyst at a temperature of 80 ... 120 ° C, characterized in that in order to achieve a degree of conversion of over 88% of nonene in a short reaction time the reaction takes place in a single monoporous structure with 10 ... 15% moisture and exchange capacity of 4.7 ... 4.9 mw / g providing increased selectivity to obtain the nonylphenol, purifying the product obtained usually by distillation under reduced pressure and in the presence of 0.1% sodium hypophosphite stabilizer.
