PROBLEM TO BE SOLVED: To provide a use of a cyclic alkane having 8-20 carbon atoms in the ring, as a settling accelerator in epoxydation of a cyclic, at least monounsaturated alkene having 8-20 carbon atoms in the ring. SOLUTION: The epoxidation is carried out by using a saturated compound as a cyclic alkane which corresponds to the alkene used, in the presence of an oxidant and a catalyst system comprising at least one metal of Group 4, 5 and 6 of the Periodic Table of the Elements, phosphoric acid and a phase transfer catalyst. The settling time is shortened according to the amount of the added alkane. COPYRIGHT: (C)2004,JPO
