The reaction temperature increases with increasing extent of conversion, the hydrochloride formed escaping as a gas. The excess phenol is distilled off when the reaction is complete. The phosphate esters can be purified by distillation. o-Cresol may not be used in the manufacture of cresyl phosphate on ecological grounds. Isopropyl-phenyl phosphate can, however, be produced using phenol mixtures, which are obtained by the alkylation of phenol with propene. 

Carvacrol and Thymol, CH3.C3H7.C6H3.OH, are phenols derived from cymene (p-methyl-isopropylbenzene). In carvacrol the hydroxyl group is ortho to the methyl radical this is shown by the fact that carvacrol is converted into o-cresol and propylene when heated with phosphorus pentoxide. In thymol the hydroxyl group is ortho to isopropyl.

Based on analysis of products distribution [25], it was concluded that there were two kinds of decomposition action hydrolysis mainly at lower temperature and pyrolysis mainly at higher temperature. At low-temperature stage, the brominated epoxy resin was mainly decomposed into bisphenol A, brome-phenol, isopropyl phenol monomer, etc., while at high-temperature stage, the brominated epoxy resin was mainly decomposed into phenol, o-cresol, p-cresol, and other small molecule compormds without bromine.

The FTIR spectra of the gas mixture evolved in thermal decomposition of Bisphenol AF poly(formal) (7) at various temperatures suggest the existence of benzene rings, C—O—C bonds, and C=C bonds. In a pyrogram of pyrolysis gas chromatography (Py-GC) of Bisphenol A (3), a-methylstyrene, phenol, p-cresol, 4-hydroxy-amethylstyrene, and isopropyl phenol are observed as major peak products. The cleavage reactions shown in Scheme (5) is suggested for the formation of phenol and 4-hydroxy-a-methylstyrene from Bisphenol A (3). 

Hydroxylation of benzene to phenol using hydrogen peroxide in the presence of heteropoly compounds was observed in this study. Other aromatic hydrocarbons that were used as substrates were toluene, ethylbenzene, o,p-xylene and isopropyl benzene under homogeneous conditions. Both side chain oxidation and ring hydroxylation were observed in presence of hydrogen peroxide. For example, toluene gave benzyl alcohol, benzaldehyde, o,p-cresols in presence of hydrogen peroxide, whereas benzaldehyde and benzyl alcohol were observed in presence of t-BuOOH.
