Synthesis of Bis-4-hydroxycoumarins via a Multi Component Reaction Using Silica Boron-sulfuric Acid Nanoparticles (SBSANs) as an Efficient Heterogeneous Solid Acid Catalyst
The silica boron sulfuric acid nanoparticles (SBSANs) as an efficient heterogeneous solid acid catalyst with both Brønsted and Lewis acidic sites catalyzed the preparation of bis-4-hydroxycoumarin derivatives using reaction of aldehydes and 4-hydroxycoumarin under mild and solvent-free condition at room temperature. This new and efficient methodology has advantages in comparison with currently ...
متن کاملChemistry of a color reaction of retinoic acid (vitamin A acid) in sulfuric acid.
Retinoic acid (vitamin A acid) (I) has long been recognized as one of the most interesting members of the retinoid family (1). A quantitation method of I was proposed by KAWASAKI et al. who estimated an absorptivity of coloration developed by 74% sulfuric acid (2). The color was found to be stable in sulfuric acid, persisting for several hours at room temperature, so they used the method for as...

متن کاملAcid-catalyzed reactions of hexanal on sulfuric acid particles: Identification of reaction products
While it is well established that organics compose a large fraction of the atmospheric aerosol mass, the mechanisms through which organics are incorporated into atmospheric aerosols are not well understood. Acid-catalyzed reactions of compounds with carbonyl groups have recently been suggested as important pathways for transfer of volatile organics into acidic aerosols. In the present study, we...
متن کاملOscillatory Bromate-Oxalic Acid-Ce-Acetone-Sulfuric Acid Reaction, in CSTR
São relatadas, pela primeira vez, a observação de oscilações periódicas, em reator agitado de fluxo contínuo (CSTR), para o sistema bromato-ácido oxálico-Ce(IV)-acetona-ácido sulfúrico. Identificou-se que a reação entre Ce(IV) e a acetona, até então não descrita na literatura e que ocorre antes dos reagentes serem adicionados ao reator, é um fator decisivo para o aparecimento de oscilações regu...
