Kinetics of formation of 1, 1′-bis (3-methyl-4-hydroxy phenyl) cyclohexane

The kinetics of reaction between cyclohexanone (0.05 mol) ando-cresol (0.1 mol) in the presence of varying mixtures of hydrochloric acid and acetic acid (2:1 V/V) were determined at four different temperatures: 40°, 50°, 60° and 70°C. The product was purified from benzene and methanol (m.p. 186°). The optimum reaction temperature, catalyst concentration and time have been determined for obtaining yields greater than 80%.
