- Аннотация: Data are given on the operation of a pilot unit for the production of 1,2-cyclohexanediol, a semiproduct in the process chain proposed for the synthesis of pyrocatechol. On the basis of the work carried out, the optimum conditions for the process of 1,2-cyclohexanediol production have been determined. It has been shown that, for the selective production of 1,2-cyclohexanediol, the heterophase reaction of hydrogen peroxide with cyclohexene must be carried out under the following conditions: temperature 40-70 degrees C; the initial hydrogen peroxide concentration is no higher than 35 mole/l; maximum initial concentration of heteropolyphosphoric acid 0.014 mole/l; initial concentration of interphase transfer catalyst 0.011 mole/l; volume ratio of organic and aqueous phases 2:1. Under these conditions of the heterophase reaction of hydrogen peroxide with cyclohexene, the target product (1,2-cyclohexanediol) yield amounts to at least 80-90 mol.%.
