Production method for epoxy compound using solid catalyst

1. A method for producing an epoxy compound comprising:

reacting a compound having a carbon-carbon double bond with hydrogen peroxide in the coexistence of the compound having a carbon-carbon double bond, aqueous hydrogen peroxide, a powder of a solid catalyst support and a powder of a solid catalyst,

wherein the solid catalyst comprises an isopolyacid, and

the isopolyacid is produced from a catalyst raw material comprising (a) tungstic acid or a salt thereof and (b) a cationic polymer.

2. The method according to claim 1 , wherein the catalyst raw material comprises an ammonium tungstate.

3. The method according to claim 1 , wherein the catalyst raw material comprises at least one cationic polymer selected from the group consisting of a salt of poly 4-vinylpyridine and a salt of poly N-alkyl-4-vinylpyridine.

4. The method according to claim 1 , wherein the compound having a carbon-carbon double bond is an alicyclic olefin compound.

5. The method according to claim 1 , wherein the compound having a carbon-carbon double bond is a compound represented by the following formula (2):

wherein R 1 to R 12 each independently represent a hydrogen atom, a halogen atom, an alkyl group that may have a substituent selected from the group consisting of a halogen atom and an alkoxy group, or an alkoxy group that may have a substituent selected from the group consisting of a halogen atom and an alkoxy group.

6. The method according to claim 1 , wherein the solid catalyst support is selected from the group consisting of phosphates, diatomaceous earth, silica, alumina, kaolin, silica alumina and calcium fluoride.

7. The method according to claim 1 , wherein the solid catalyst support is apatite.
