Funnels Furfuryl alcohol

Place 200 g. (172 -5 ml.) of redistilled furfural (1) in a 1 litre beaker, provided with a mechanical stirrer and surrounded by an ice bath. Start the stirrer and, when the temperature has fallen to 5-8°, add a solution of 50 g. of sodium hydroxide in 100 ml. of water from a separatory funnel at such a rate that the temperature of the reaction mixture does not rise above 20° (20-25 minutes) continue the stirring for a further 1 hour. Much sodium furoate separates during the reaction. Allow to cool to room temperature, and add just enough water to dissolve the precipitate (about 65 ml.). Extract the solution at least five times with 60 ml. portions of ether in order to remove the furfuryl alcohol the best results are obtained by the use of the continuous extraction apparatus (charged with 350 ml. of ether) depicted in Fig. //, 44, 2. Keep the aqueous layer. Dry the ethereal extract with a httle anhydrous... 

Technical 2-furaldehyde (1 kg) in a 4-1 vessel is cooled to 5-8° whilst being stirred and a solution of sodium hydroxide (275 g) in water (350 ml) is allowed to run in from a separatory funnel at a rate such that the temperature of the mixture does not exceed 20°. The whole is then stirred for a further hour, then sufficient water is added to dissolve the crystals of sodium furoate, and the solution is perfused with ether (1500-2000 ml) which removes most of the furfuryl alcohol.
