Abstract

Inventia se refera la un procedeu de purificare a o-aminofenolului prin cristalizare din apa, prin care se obtine un produs cu stabilitate marita, de calitate superioara, folosind un agent de legare care formeaza cu ionii de metale grele din solutie compusi insolubili, care se îndeparteaza prin filtrare. o-Aminofenolul astfel purificat poate fi utilizat de industria cosmetica.
