What is Selective oxidation of 2-isopropylnaphthalene to 2-isopropylnaphthalenehydroperoxide in a gas–liquid reaction system using CuO+NaOHaq catalyst about?

The catalytic activities of CuONaOH aq and Cu 2 ONaOH aq in the liquid-phase selective oxidation of 2-isopropylnaphthalene (2-IPN) to 2-isopropylnaphthalenehydroperoxide (2-IPNHP) were compared, and the process parameters using CuONaOH aq catalyst were investigated. It was found that the atomic ratio of copper to sodium ions of the catalyst system affected the product distribution, a temperature 1008C was favourable for the selective production of 2-IPNHP, and the degree of back-mixing and liquid-phase mass transfer limitation markedly affected the conversion and selectivity. 2-IPNHP (1.254 mol dm À3 ) was produced from 2-IPN (6.9 mol dm À3 ) with 76% selectivity in a bubble column reactor with molecular oxygen as the oxidizing gas. An oxidation mechanism that depends on the unique combined catalytic behaviour of CuONaOH aq was proposed.
