Abstract
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 comp…
