| Abstract: | 2-Furaldehyde oxime was synthesized using furfural and oxammonium hydrochloride as the starting materials.The effects of the pH value,the reaction time,the temperature and the ratio of the reagents were studied.The optimized reaction conditions were obtained as follows:molar ratio of oxammonium hydrochloride to furfural 1.3 to 1,the reaction temperature 20℃,the reaction time 1 h.The target product was resulted in overall yield of 43% with purity above 98.7%. |
