TL;DR: In this article, a zeolite with 10 oxygen-atom rings as the inlets of the major pores is used as an adsorbent and brought into contact with crude 2,6-xylenole to effect adsorption of impurities.
Abstract: PURPOSE:A zeolite with 10 oxygen-atom ring as the inlets of the major pores is used as an adsorbent and brought into contact with crude 2,6-xylenole to effect adsorption of impurities, thus giving high-purity 2,6-xylenol. CONSTITUTION:As an adsorbent, is used a zeolite having major pores whose inlets consists of 10 oxygen-atom rings such as crystalline aluminosilicate. The zeolite is brought into contact with crude 2,6-xylenol containing phenol and cresol isomers as impurities to effect adsorption of these impurities to separate 2,6-xylenol. The above adsorbent selectively adsorbs phenol and cresol isomers. USE:2,6-Xylenol is used as a raw material of a heat-resistant engineering plastic [poly(2,6-dimethyl-1,4-phenylene oxide)].
