The invention claimed is: 1. A method for producing a polyol-ether compound, comprising: subjecting a compound represented by the following formula (1) to hydrogenation reduction in the presence of a hydrogenation catalyst to obtain a polyol-ether compound represented by the following formula (2): wherein: R 1 and R 2 , which may be the same as or different from each other, each represent a linear or branched alkyl group comprising 1 to 6 carbon atoms; and R 3 represents a linear or branched alkyl group comprising 1 to 6 carbon atoms or a hydroxymethyl group. 2. The method according to claim 1 , wherein R 3 is a methyl group or an ethyl group. 3. The method according to claim 1 , wherein R 3 is a hydroxymethyl group. 4. The method according to claim 1 , wherein R 1 and R 2 are each a methyl group. 5. The method according to claim 1 , wherein the compound represented by the general formula (1) is subjected to hydrogenation reduction in a reaction solvent comprising an ether compound, a saturated hydrocarbon compound, or both. 6. The method according to claim 1 , wherein the hydrogenation catalyst is a solid catalyst comprising palladium. 7. The method according to claim 1 , wherein the hydrogenation catalyst is a solid catalyst comprising a zirconium compound or an apatite compound. 8. A polyol-ether compound represented by the following formula (3): wherein R 1 and R 2 , which may be the same as or different from each other, each represent a linear or branched alkyl group comprising 1 to 6 carbon atoms. 9. The polyol-ether compound according to claim 8 , wherein R 1 and R 2 are each a methyl group. 10. The method according to claim 2 , wherein R 1 and R 2 are each a methyl group. 11. The method according to claim 2 , wherein the compound represented by the general formula (1) is subjected to hydrogenation reduction in a reaction solvent comprising an ether compound, a saturated hydrocarbon compound, or both. 12. The method according to claim 2 , wherein the hydrogenation catalyst is a solid catalyst comprising palladium. 13. The method according to claim 2 , wherein the hydrogenation catalyst is a solid catalyst comprising a zirconium compound or an apatite compound. 14. The method according to claim 3 , wherein R 1 and R 2 are each a methyl group. 15. The method according to claim 3 , wherein the compound represented by the general formula (1) is subjected to hydrogenation reduction in a reaction solvent comprising an ether compound, a saturated hydrocarbon compound, or both. 16. The method according to claim 3 , wherein the hydrogenation catalyst is a solid catalyst comprising palladium. 17. The method according to claim 3 , wherein the hydrogenation catalyst is a solid catalyst comprising a zirconium compound or an apatite compound. 18. The method according to claim 4 , wherein the compound represented by the general formula (1) is subjected to hydrogenation reduction in a reaction solvent comprising an ether compound, a saturated hydrocarbon compound, or both. 19. The method according to claim 4 , wherein the hydrogenation catalyst is a solid catalyst comprising palladium. 20. The method according to claim 4 , wherein the hydrogenation catalyst is a solid catalyst comprising a zirconium compound or an apatite compound.
