What is 4-Cyclohexylphenol?
The Uses of 4-Cyclohexylphenol
4-Cyclohexylphenol is a derivative of Cyclohexylphenol (CHP), which is widely used in the preparation of dyes, resins, and biocides[2]. 4-Cyclohexylphenol labelled with 35s can be used for metabolic studies[3].
Synthesis
4-Cyclohexylphenol is obtained by hydroalkylation of phenol using phenol as a raw material in the presence of a palladium catalyst and a molten salt (NaCl-AlCl3)[1]. The specific synthesis steps are as follows:
The hydroalkylation of phenol in the presence of palladium catalyst and fused salt (NaCl-AlCl3) under hydrogen pressure was carried out. By using 1% Pd-Al2O3 (1 g) and the fused salt (1 : 1 mol ratio, 6 g), 4-cyclohexylphenol was obtained selectively from 1 (30 g) in a yield of 31.9% at 120°C for 4.5 h.
