Embodiment
[0064] Hereinafter, the present invention will be further specifically described with reference to Examples and the like.
[0065] First, the preparation example of the ether compound is described.
preparation example 1-1
[0066] Preparation Example 1-1 (Steps A to C)
[0067] To 800 ml of 2-methoxyethanol, 100 g (purity 95.0 g) of bis(2,4,6-trichlorophenoxymethyl) ether containing 5 wt% alumina and 50% water were added of 91.4 g (pure content 45.7 g, 3.0 equiv.) of sodium methanethiolate, followed by stirring at 100 to 105° C. for 4 hours under nitrogen atmosphere. The reaction mixture was cooled to room temperature and filtered. Thereafter, hexane and 10% aqueous NaOH solution were added, followed by stirring. The mixture was left to stand and then separated. The obtained organic solvent layer was dried over anhydrous sodium sulfate, and then the solvent was distilled off under normal pressure, whereby 32.2 g of bis(methylthiomethyl)ether (referred to as compound Y) was obtained as a residue. .
