| Abstract: | Aeetoin as a flavor compound has been widely used in all kinds of foodstuff and drinking. The acetoin（3-hydroxy-2- butanone） was synthesized by oxidation of 2-butanone with sodium bromate followed by basic hydrolysis. The effects of mole ratio of the reagents, acidity, reaction temperature and reaction time on the yield were investigated. The optimum reaction conditions for this reaction were found as follows： mole ratio of 2-butanone to sodium bromate, to sodium hydroxide 1 ： 1.2 ： 1, 10% H2SO4, reaction temperature 45℃, reaction time 9 h. Under this condition, the total yield of acetoin was up to 62% and its purity was over 99%. |
