Functionalized MCM-41 as a catalyst for the aldol condensation of 4-isopropylbenzaldehyde and propanal

Popis výsledku v původním jazyce

Aldol condensation of 4-isopropylbenzaldehyde and propanal was carried out using functionalized MCM-41. The aldol condensations are usually performed using acidic or basic catalysts and due to this fact, the modification of MCM- 41 was realized using post-grafting method by two acid groups (3-propylsulfoxy, 3-propylcarboxy) and one basic (the 3-(1,2-diethylamino)propyl) group. MCM-41 treated by sulfuric and nitric acid was also used. The prepared functionalized materials were characterized by BET, elemental analysis and UV-Vis spectroscopy. The optimal reaction conditions were found: the temperature of reaction mixture 100 C, the molar ratio of reactants 4 isopropylbenzaldehyde:propanal = 1:2, the amount and the type of the catalyst: 50 wt% of MCM SO3H(compared to the amount of 4-isopropylbenzadehyde), the addition time of propanal 90 min and suitable solvent for the reaction was toluene. Using the optimal reaction conditions the yield of forcyclamenaldehyde was 45 %. The obtained res
