The methylation is carried out by contacting gaseous phenol and methanol at elevated temperatures in the presence of a solid acid catalyst: [2] [3] C 6 H 5 OH + 2 CH 3 OH → (CH 3) 2 C 6 H 3 OH + 2 H 2 O. Challenges associated with the production is the similarity of the boiling points of cresols and this xylenol.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

These residue contains a few percent by weight of xylenols as well as cresols and phenol. 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: [1] C 6 H 5 OH + 2 CH 3 OH → (CH 3) 2 C 6 H 3 OH + 2 H 2 O
The acidity of the methylene group in diphenylmethane is due to the weakness of the (C 6 H 5) 2 CH–H bond, which has a bond dissociation energy of 82 kcal mol −1 (340 kJ mol −1). [5] This is well below the published bond dissociation energies for comparable C–H bonds in propane , where BDE((CH 3 ) 2 CH–H)=98.6 kcal mol −1 , and ...
