Facile Knoevenagel condensation Using Sulfonic Acid Functionalized Nanoporous silica (SBA-Pr-SO3H)
Knoevenagel condensation between barbituric acid and aldehyde was investigated in the presence of sulfonic acid functionalized nanoporous silica (SBA-Pr-SO3H) and resulted in the formation of arylidene and bis-arylidene barbiturates. Excellent yields and short reaction times are related to the high efficiency of SBA-Pr-SO3H that the reactions take place easily in its nano-pores. SBA-Pr-SO3H as ...

متن کاملAmine-Functionalized Sugarcane Bagasse: A Renewable Catalyst for Efficient Continuous Flow Knoevenagel Condensation Reaction at Room Temperature.
A biomass-based catalyst with amine groups (-NH₂), viz., amine-functionalized sugarcane bagasse (SCB-NH₂), was prepared through the amination of sugarcane bagasse (SCB) in a two-step process. The physicochemical properties of the catalyst were characterized through FT-IR, elemental analysis, XRD, TG, and SEM-EDX techniques, which confirmed the -NH₂ group was grafted onto SCB successfully. The c...
متن کاملApplication of Nanoanalysis: Amine-Functionalized Mesoporous Silica nanoparticles for Mercury Speciation in Human Samples
Mercury (Hg) causes hazardous cumulative effects in humans; like central nervous system disorders,hypertension and chromosomal aberrations. Therefore, due to high toxicity and bioaccumulationfactor, mercury determination and speciation in human blood is very important. A sensitive,accurate, precise and inexpensive method was demonstrated for preconcentration and speciationof ultra-trace mercury...
