Methylphenols

Fig. 1. A single step perturbation fails for the mutation of p-methylphenol to p-methoxyphenol because no configuration with a cavity large enough to accommodate the methoxy group is sampled in a simulation of p-methylphenol in water.

NMR spectrum of 3 methylphenol m cresol) Notice that contrary to what we might expect for a compound with seven peaks for seven different carbons the intensities of these peaks are not nearly the same The two least intense signals those at 8 140 and 8 157 correspond to carbons that lack attached hydrogens... 

The hydrolysis of p bromotoluene with aqueous sodium hydroxide at 300°C yields m methylphenol and p methylphenol in a 5 4 ratio What is the meta—para ratio for the same reac tion carried out on p chlorotoluene" ... 

IMINES, CYCLIC] (Vol 14) 2,2y-Thiobis(6-tert-butyl-4-methylphenol) [90-66-4]... 

Gymene. Methyhsopropylben2ene [25155-15-1] can be produced over a number of different acid catalysts by alkylation of toluene with propylene (63—66). Although the demand for cymene is much lower than for cumene, one commercial plant was started up in 1987 at the Yan Shan Petrochemical Company in the People s RepubHc of China. The operation of this plant is based on SPA technology offered by UOP for cumene. The cymene is an intermediate for the production of y -cresol (3-methylphenol) [108-59-4]. 

Other common names are cresol and xylenol for methyl- and dimethylphenols respectively, eg, o-cresol is 2-methylphenol, and 2,5-xylenol is...
