Versuchsvorschrift

Under nitrogen stream, to a 2-L reactor provided with a stirrer, thermometer, condenser and gas inlet tube, 320 g (2 mol) of 2,4-diethyl-1,5-pentanediol, 311 g (1.5 mol) of n-nonylbromide and 12 g of tetrabutylammonium bromide were put, to which 532 g of 52 mass/volume % aqueous sodium hydroxide was added and heated at 70 to 80 degrees C. for six hours with stirring. After the reaction, the mixture was cooled and left still overnight to deposit white crystal. A liquid layer is transferred to a separating funnel by decantation. The white crystal was washed with 20 mL of hexane. The washing liquid of hexane was added to the liquid layer.
