実験手順

To a 1.5 L autoclave equipped with a stirrer and a heating means were added 154 g (1.0 mol) of diethyl sulfate, 101 g (1.0 mol) of triethyl amine and 690 g (15 mol) of ethanol. Stirring was initiated after the autoclave was sealed. The autoclave was heat to 140° C., and pressure was 1.0 MPa. The reaction was kept at 140° C. for 4 h. Then the reaction mixture was cooled to room temperature and discharged into a 1 L three-necked flask. 80 g (2.0 mol) of sodium hydroxide was added thereto. The reaction mixture was heated at 45° C. for 4 h while stirring. After filtration, part of ethanol was distilled off from the filtrate. Then 500 g of water was added while ethanol was distilled off (part of water was entrained out), to give 604 g of tetraethyl ammonium hydroxide solution. The content of tetraethyl ammonium hydroxide was found as 23.3 wt.-% and the total reaction yield was 95.7%.
