Resumo: Two synthetic application involving phase transfer catalysis were studied. The first application involved eletroxidation of anthracene to anthraquinone using low cost ghraphite eletrodes and tetrabutilammonium dicromate as catalyst. The electroxidation was run in a new electrolityc cell equipped with a rotatory cylindrical cathode; the desired product was obtained in yield superior to 90%. The second study included the alkylation of diethyl malonate using tetra-n-butylammonium hydrogensulphate as catalyst to obtain an important intermediate for the preparation of barbiturates

A primeira aplica??o envolveu a eletroxida??o de antraceno a antraquinona, utilizando-se eletrodos de grafite de baixo custo e dicromato de tetrabutilam?nio como catalisador de transfer?ncia de fases. A eletroxida??o foi realizada em um novo tipo de c?lula eletrol?tica, constando de catodo cil?ndrico m?vel, obtendo-se rendimentos superiores a 90%. Na outra, foi estudada a alquila??o de malonato de etila usando hidrogenossulfato de tetra-n-butilam?nio como catalisador, para obter um importante intermedi?rio para a prepara??o de barbituratos.Submitted by Celso Magalhaes (celsomagalhaes@ufrrj.br) on 2020-11-18T15:55:21Z No. of bitstreams: 1 1993 - H?lio Arag?o dos Santos.pdf: 1172143 bytes, checksum: 7f7a0f723a535312da7d51f8c49b962c (MD5)Made available in DSpace on 2020-11-18T15:55:21Z (GMT).
