Furthermore, a method has been proposed in which an olefin compound and hydrogen peroxide are reacted with a nitrile compound in the presence of an alkali metal salt (JP-A-7-206835). In this method, an epoxy compound is produced at a maximum yield of 71%. It is said that it can be produced, but requires a large amount of hydrogen peroxide for olefin compounds,
There was a problem that it was hard to say that it was economical.
