摘要
在稀氢氧化钠溶液中,由苯甲醛和乙醛缩合制备肉桂醛.并对影响肉桂醛质量收率的因素(碱浓度、碱用量、反应时间、反应温度以及反应摩尔比)进行了分析,探索出肉桂醛合成的优惠反应条件,收率达到5 6 .6 7% .
In aqueous sodium hydroxide, with benzene as the catalyst, cinnamaldehyde is synthesized from the reaction of benzaldehyde and acetaldehyde. The factors affecting the quality and recovery of cinnamaldehyde, such as the volume of alkali, its concentration, the temperature, the time and the molar ration, are analyzed, as well as the optimum conditions for synthesizing cinnamaldehyde, with 56.67% as its recovery.
