preparation of piperonal (MW irradiationon) | Bookmark | |||||
The effect of microwave irradiation on organic chemical synthesis were examined.While having studied in detail the preparation of piperonal under microwave irradiationon an organic solid support, -such like alumina, silica, clays, sodium-, potassium-,calcium carbonate,- in the absence of any organic solvents (in dry media) , or inthe presence of solvents, the synthesis carried out in dry media by using microwave irradiation seemed to be more advantageous. Higher reaction rate and better selectivity were observed, the downstream processing was found to be easier and moreeffective (... A. Vass). ... Conference lectures and posters ... 9.
