| Application: | p-Cresol (4-Methylphenol) has been used in a study for the identification of volatile compounds from the meat samples aged for 4- and 8-days by gas chromatography-mass spectrometry. |
| General description: | Cresols exist in three isomeric forms: o-, m- and p-cresol. They have phenolic odor. p-cresol contamination in water samples has been determined by employing polyphenol oxidase at a graphite foil electrode. Chemical changes involved during the adsorption of p-cresol on the activated carbon at 278, 298 and 323K have been investigated. p-Cresol (4-Methylphenol) affords 4-methylcyclohexanol on hydrogenation in the presence of MoO3, MoO2, and MoS2 catalysts. It affords 4-methyl-2-nitrophenol, via reaction with nitrogen dioxide in solution. |
