Sobre IBD

O selênio e os compostos organosselenados são utilizados em diversas áreas da ciência e da tecnologia. Muitos métodos clássicos de transformação do selênio e seus compostos levam muito tempo (4-6 horas). Um dos métodos muito eficazes da química verde é a síntese orgânica em condições de ativação por micro-ondas, que em muitos casos permite reduzir significativamente o tempo de reação e, em alguns casos, dispensar o uso de solventes. O livro analisa uma cadeia ecologicamente correta de transformações sucessivas de selênio sujo em dióxido de selênio de alta pureza, depois em éteres de ácido selênico e, por fim, a regeneração de selênio de alta pureza em condições de ativação por micro-ondas.
