The Process of 4-Hydroxybiphenyl Synthesis from 4-Isopropylbiphenyl

摘要

The kinetics of the oxidation of 4-isopropylbiphenyl (1) in the liquid phase by oxygen to 1-(1,1'-biphenyl-4-yl)-1 -methylethyl hydroperoxide (2) was investigated. The oxidizability of 1 in the temperature range from 60°C to 120°C and the overall energy activation of oxidation were determined. Long-term oxidation of 1 to 2 in the temperature range of 80-120°C was investigated, and the yield and selectivity of the process were determined. Pure 2 was obtained, and its properties were defined. 4-Hydroxybiphenyl was obtained as a result of the acidic decomposition of 2.
