The invention relates to an oscillatory flow reactor used for preparing cumene hydroperoxide (CHP) in catalytic oxidation of cumene and a method for preparing CHP in catalytic oxidation of the cumene. The oscillatory flow reactor comprises a feed distribution section, a reaction section, a gas-liquid separation section and a condensation section; the feed distribution section comprises gas inlets, a gas distributor, a liquid inlet and a liquid-solid separator, and the liquid-solid separator is connected with an oscillation pump; the main body of the reaction section comprises a corrugated reaction tube with multiple sections which are in sectoral arc connection to form a concave-convex corrugated shape integrally, a heat tracing layer is arranged on the outer side of the corrugated reaction tube, and heat tracing medium enters from a heat tracing liquid inlet and flows out from a heat tracing liquid outlet; each of the upper, middle and lower section of the main body of the reaction section is provided with a
