The present invention provides a method for producing an alicyclic diepoxy compound at a higher yield by carrying out epoxidation of an alicyclic olefin compound at a higher reaction rate. The method is a method for producing an alicyclic diepoxy compound represented by formula (1) below by reacting an alicyclic olefin compound represented by formula (2) below with hydrogen peroxide in the coexistence of the alicyclic olefin compound represented by formula (2) below, a hydrogen peroxide solution, a powdered solid catalyst support and a powdered solid catalyst all together: wherein Rto Rare each hydrogen, halogen, an alkyl group optionally having halogen or an alkoxy group optionally having a substituent.

Method for producing alicyclic diepoxy compound

A method is provided for carrying out epoxidation of an olefin compound with good productivity. The method produces an epoxy compound by reacting a compound having a carbon-carbon double bond with hydrogen peroxide by carrying out repeatedly or continuously the following steps: (1) reacting a compound having a carbon-carbon double bond with hydrogen peroxide in the coexistence of (a) the compound having a carbon-carbon double bond, (b) a hydrogen peroxide solution, (c) a powdered solid catalyst support, and (d) a powdered solid catalyst, and optionally further (e) an organic solvent to produce an epoxy compound; (2) separating the epoxy compound reaction product from the reaction mixture produced in (1); and (3) adding (d) and also adding (a), (b), (c), and optionally further (e) to the mixture of the powdered solid catalyst support and powdered solid catalyst after separating the reaction product in (2).

It is an object to provide a novel material that can quickly form metal silver even at a low temperature of approximately 210&#xb0; C. or less. This serves as a metal silver forming material that includes a silver &#x3b2;-ketocarboxylate. By heating this forming material, it is possible to form metal silver quickly even at a low temperature of approximately 210&#xb0; C. or less. Examples of the silver &#x3b2;-ketocarboxylate include silver isobutyrylacetate, silver benzoylacetate, silver acetoacetate, silver propionylacetate, silver &#x3b1;-methylacetoacetate, and silver &#x3b1;-ethylacetoacetate.
