Abstract:

Clusia nemorosa is distributed throughout Brazil and its extract is widely used in popular medicine to treat different diseases. Although the popular use of extract of C. nemorosa, the scientific reported on their pharmacological and phytochemical analysis are scarce. In the present study, we aimed to evaluate the antinociceptive and antiinflammatory effect of hexane extract of Clusia nemorosa-derived stem bark (EHC). To evaluate the antinociceptive effect of EHC classical models of the study of pain were used, such as the abdominal writhing test induced by acetic acid, formalin test and hot

Abstract:

The various inorganic solids that may be employed as heterogeneous catalysts in organic reactions are discussed in Chapter 1. In the present climate, heterogeneous catalysts are seen as more environmentally acceptable alternatives to homogeneous Lewis acid type catalysts. Chapter 2 describes the Friedel-Crafts acylation of aromatics. Discussion focuses on both the classical and solid catalysed reactions. The study of a pharmaceutical intermediate is described in Chapter 3. The aims of the work described were to develop an efficient and commercially viable process for the production of 1-(4-met

Abstract:

A study has been undertaken to establish whether it is possible to introduce unsaturation into Friedel - Crafts ( F/C) polymers, so that they can be cured free - radically via the unsaturation. It was hoped that the hydrocarbon - only nature of the polymer backbone, and the absence of hydrophilic cure catalysts would produce a material of low water absorption. The introduction of unsaturation has been approached in two ways. The first was to synthesize Friedel - Crafts prepolymers with ethyl side - chains. The side - chains were then tb be chlorinated, and then dehydrochlorinated to produce vi

Abstract:

Alginates are polysaccharides derived from brown algae, available in nearly unlimited amounts at very low prices. In the presence of some divalent metals, these renewable biopolymers can readily form hydrogels, solvogels and aerogels, characterized by high surface areas, good mechanical properties, tolerance to different media, and easy manageability. For these reasons, alginates are nowadays being thoroughly studied in heterogeneous catalysis; several applications in supported metal catalysis and as heterogeneous Brønsted acids have emerged. However, none of these studies has given an answer

Abstract:

Neste trabalho foi realizada a funcionalização de grafite sem prévio tratamento em condições de Fridel-Crafts. Considerando que a grafite não possui hidrogênio em sua estrutura, não se observa uma reação de substituição eletrofílica. Por outro lado, o trabalho mostra o papel da umidade presente no grafite na reação de funcionalização. Dessa forma, foi proposto um mecanismo para a reação com a participação da água adsorvida na grafite estabilizando o carbocátion formado. O grafite funcionalizado obtido na reação foi utilizado como material eletródico. Para a reação de funcionalização, quatro

Abstract:

The failure of politics is closely connected with deeply rooted misconceptions about the term politics. The author argues that a re-reading of Immanuel Kant's work "The Perpetual Peace" written 200 years ago offers a challenging possibility for a new conceptualization of politics, morality and peace. Morality is seen by Kant as an essential dimension of politics and the implementation and acknowledgement of laws by moral demands is defined as a precondition for a community of free citizens. In its public discourse politics does require law and morality. Deriving future rights from existing law
