    • The present invention provides: a solid catalyst which enables a person to simply and efficiently carry out an etherification reaction; and a process by which an ether compound is simply and efficiently produced using the solid catalyst. The solid catalyst is a first solid catalyst comprising at least one rare earth element, or is a second solid catalyst comprising a metallic compound which includes a metal atom and a nonmetal atom bonded to the metal atom, wherein the metallic compound has molecular orbitals including: at least one orbital (L) having an energy of E.sub.L (eV) which satisfies E.sub.LUMO .ltoreq.E.sub.L .ltoreq.(E.sub.LUMO +0.05) wherein E.sub.LUMO is an energy (eV) of the lowest unoccupied molecular orbital around the metal atom; and at least one orbital (H) having an energy of E.sub.H (eV) which satisfies (E.sub.HOMO -0.02).ltoreq.E.sub.H .ltoreq.E.sub.HOMO wherein E.sub.HOMO is an energy (eV) of the highest occupied molecular orbital around the nonmetal atom; wherein at least one of orbitals (L) and at least one of orbitals (H) are both orientational. The process for producing an ether compound comprises the step of carrying out a reaction between an organic compound having a hydroxyl group and an unsaturated carboxylic acid compound or an epoxy compound in the presence of either or both of the first and the second solid catalyst, thus forming the ether compound.

    • The present invention is related to a method for producing a resin compact containing an epoxy resin, a curing agent, a curing accelerator and an inorganic filler. The method includes a kneading and crushing process for preparing a first powder material obtained by mixing, heat-melting, kneading and crushing a first component containing the epoxy resin and the curing agent and the inorganic filler, but not containing the curing accelerator; a pulverizing process for preparing a second powder material obtained by pulverizing a second component containing the curing accelerator; a mixing process for preparing a resin composition by dispersing and mixing the first powder material and the second powder material; and a molding process for obtaining the resin compact by compression-molding the resin composition. This makes it possible to obtain a resin compact (particularly, a resin compact for encapsulation) having superior long term storage stability at room temperature, good curable property and fluidity.
