Reaction Conditions:
with hydrogen;sodium hydroxide in water at 25; under 7500.75 Torr; for 1 h;Autoclave;Pressure;Reagent/catalyst;Solvent;Temperature;
Steps:
2.4; 3-7; 3; 4 4. Preparation of 1,3-butanediol
0.44 g (5 wt%) of the activated Raney Nickel prepared in Example 1, 5 ml of 1N NaOH, and 70 ml of distilled water were added to the prepared high-pressure reactor, and 8.8 g of 4-hydroxy-2-butanone Is added.Hydrogen gas is introduced into the high-pressure reactor, the air in the flask is replaced, and hydrogen is again pressurized to adjust the pressure to 10 bar. The mixture is stirred for 1 hour while maintaining the temperature at 25 ° C.After completion of the reaction, hydrogen gas was removed, and 1,3-butanediol was neutralized with 1N HCl.Finally, the solid was removed by filtration. The solid was sufficiently washed with distilled water, and the solvent of the collected filtrate was distilled under reduced pressure, and the residue was analyzed.
