| titleOfInvention | One kind circulation prepares benzoic green synthesis method |
| abstract | The invention discloses one kind circulation to prepare benzoic green synthesis method.Its step is：Polyethylene glycol 400, vitamin B are sequentially added in the reactor 1 , Anhydrous potassium carbonate, magnetic agitation is after 5 minutes at room temperature, benzaldehyde is added, after 3h is reacted in thin-layer chromatography monitoring, colourless solution is changed into faint yellow, as reaction is carried out, white solids increase in flask, react after 5h and terminate, stand 10min filterings, filter cake obtains white powdery solid, yield 93% with 95% ethyl alcohol recrystallization；Filtrate is added in reaction bulb, again addition Anhydrous potassium carbonate and benzaldehyde, beginning first time circular response, after 5h, reaction terminates, and stands, filters, and filter cake obtains white powdery solid, yield 95% with 95% ethyl alcohol recrystallization；For circular response after totally 15 times, reaction yield and reaction time are substantially unchanged.Synthetic method of the present invention is simple, and reaction cost is low, high catalytic efficiency, and yield is high, green. |
