Abstract

Inventia se refera la un procedeu de separare a fenolului din apa prin extractia acestuia cu un agent de extractie, prin care, în scopul recuperarii fenolului prin reducerea concentratiei sale în apa de la 6...10% pâna la 0,3...2%, eventual pâna la 0,1...1% în greutate, se agita la o temperatura de 80...100 degree C emulsie formata din solutie apoasa fenolica si agentul de extractie constituit din fractiunea de produse secundare rezultata la fabricarea bisfenolului, din care, eventual, s-a distilat fenolul si care contine 0,6% fenol, 0,1...12% p-izopropenilfenol, 0,4...7% 1,3,3-trimetil-6-hidroxiinden-1, 5...11% diamina, 14...21% dimeri de p-izopropenilfenol, 0,8...23,6% trisfenoli, 4...8% bisfenol A si izomerii sai, la un raport gavrimetric de 1:2,3...4 agent de extractie:solutie fenolica, adaugîndu-se eventual un schimbator cationic cu continut de hidrogen.The invention relates to a process for separating phenol from water by extracting it with an extraction agent, whereby, in order to recover the phenol by reducing its concentration in water from 6 ... 10% to 0.3 ... 2%, possibly up to 0.1 ... 1% by weight, is stirred at a temperature of 80-100 ° C, an emulsion composed of phenolic aqueous solution and the extraction agent consisting of the by-product fraction resulting from the manufacture of bisphenol , from which the phenol has been distilled and contains 0.6% phenol, 0.1 ... 12% p-isopropenylphenol, 0.4 ... 7% 1,3,3-trimethyl-6-hydroxyinden- 1, 5 ... 11% diamine, 14 ... 21% p-isopropenylphenol dimers, 0.8 ... 23.6% trisphenols, 4 ... 8% bisphenol A and its isomers at a gavimetric ratio 1: 2,3 ... 4 extraction agent: phenolic solution, eventually adding a hydrogen-containing cation exchanger.
