Procedure

To a 1" ID 8" long cylindrical glass reactor, fitted with a gas sparger, a magnetic stirrer and a condenser, was charged 5.0 g of chromium exchanged resin prepared above, 25 g of tetralin (99.3 weight percent purity) and 2 g of 2-methyl-5-ethyl pyridine. The reactor with contents was immersed in a hot-oil bath whose temperature was controlled at 120°±2° C. When the temperature of the reactants had risen to 120° C., oxygen flow at 235 standard ml/minute was started. At the end of two hours the reaction mixture analyzed 18.35 percent 1-tetralone, 1.81 percent 1-tetralol, by vapor phase chromatography, giving a 1-tetralone/1-tetralol ratio of 10.1. Tetralin hydroperoxide level was 1.3 percent by weight.
