xylenol การใช้

• Xylenol has one hydroxyl group and two methyl groups and a total of 6 isomers exist.
• It is an aqueous solution of ferrous ammonium sulfate, sorbitol, sulfuric acid and xylenol orange.
• In one study 2, 6-xylenol is oxidized with iodosobenzene diacetate with a fivefold excess of the phenol.
• 2, 6-Xylenol is a monomer for poly ( p-phenylene oxide ) engineering resins through carbon-oxygen oxidative coupling.
• A 2nd order polynomial relationship between absorption and concentration is sometimes encountered for very large, complex molecules such as organic dyes ( Xylenol Orange or Neutral Red, for example ).
• Fricke solutions with various gelling agents such as gelatine, agarose, sephadex and polyvinyl alcohol ( PVA ) were investigated along with chelating agents such as xylenol orange ( XO ) to reduce diffusion.
• The main xylenols in such tar are the 3, 5-, 2, 4, and 2, 3-isomers . 2, 6-Xylenol is produced by methylation of phenol using methanol in the presence of metal oxide catalysts:
• The creosote is a combination of natural phenols : primarily guaiacol and creosol ( 4-methylguaiacol ), which will typically constitute 50 % of the oil; second in prevalence, cresol and xylenol; the rest being a combination of monophenols and polyphenols.
