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

Abstract

The kinetics of reaction between cyclohexanone (0"05 mol) and o-cresol (0-1 tool) 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~ The product was purified from benzene and methanol (m.p. 186~ The optimum reaction temperaturr catalyst concentration and time have been determined for obtaining yields greater than 80%.

Measurement, Correlation, and Thermodynamic Properties of the Solubility of Bisphenol Z (BPZ) in Nine Mono and (Tetrahydrofuran + 1-Propanol) Binary Solvents

“…Bisphenol Z, further designated as BPZ, was synthesized according to reported methods. , A Friedel–Crafts catalyst of HCl/CH 3 COOH (2:1 v/v, 100:50 mL) was charged in a round-bottom flask equipped with a condenser and stirrer containing a mixture of phenol (1 mol) and cyclohexanone (0.5 mol) and heated at 328.15 K for 4 h. The dark pink product thus obtained was filtered and washed with hot water to remove acids and unreacted phenol and cyclohexanone. A 2N NaOH solution was used to dissolve the washed product, and the solution was filtered through a cotton plug to remove any resinous residues.…”
