A novel method of synthesizing solid phase adsorbent silica modified with xylenol orange: application for separation, pre-concentration and determination o... Quantitative sorption of uranium was observed above pH 3 and complete desorption can be achieved using 0.2 M sodium pyrophosphate solution. The ...
The molar ratios of alkyl phenol or alkyl phenyl ether to phenol itself in the feed are preferably from 1:3 to 2:1. The examples describe the preparation of o, m, and p-cresols from xylenols; cresols and xylenols from 2,3,5,6-tetramethyl phenol; o-cresol from anisole; and 2-...
