O que \u00e9 TEMPO?<\/strong><\/h2>\n

O \u00f3xido de 2,2,6,6-tetrametilpiperidina, abreviado como TEMPO, \u00e9 um radical nitr\u00f3xido de piperidina. O TEMPO \u00e9 vermelho-alaranjado, f\u00e1cil de sublimar em cristal ou l\u00edquido e \u00e9 facilmente sol\u00favel em solventes como \u00e1gua, etanol e benzeno.<\/h4>\n

Ele tem a fun\u00e7\u00e3o de capturar radicais livres e extinguir o oxig\u00eanio singlete, al\u00e9m de ser um catalisador de oxida\u00e7\u00e3o muito eficaz, que pode oxidar \u00e1lcoois prim\u00e1rios em alde\u00eddos e \u00e1lcoois secund\u00e1rios em cetonas.<\/h4>\n

Devido ao efeito de impedimento est\u00e9rico dos quatro grupos metil, o TEMPO \u00e9 relativamente est\u00e1vel \u00e0 luz e ao calor e \u00e9 um catalisador de oxida\u00e7\u00e3o muito eficaz, que pode oxidar \u00e1lcoois prim\u00e1rios e secund\u00e1rios nos compostos carbon\u00edlicos necess\u00e1rios. Ele tem as caracter\u00edsticas de alto rendimento, boa seletividade, boa estabilidade e capacidade de reciclagem.<\/h4>\n

2,2,6,6-Tetrametilpiperidinooxi \/ TEMPO Uso<\/strong><\/h2>\n

1. A oxida\u00e7\u00e3o catal\u00edtica da celulose usando TEMPO \u00e9 considerada um m\u00e9todo eficaz. Ele pode oxidar totalmente a estrutura da fibra lignocelul\u00f3sica em seu sistema de rea\u00e7\u00e3o de suspens\u00e3o e estabelecer uma boa condi\u00e7\u00e3o b\u00e1sica para a dissocia\u00e7\u00e3o mec\u00e2nica subsequente.<\/h4>\n

2. O TEMPO \u00e9 um radical nitroxil est\u00e1vel sol\u00favel em \u00e1gua. Ele pode ser usado para catalisar seletivamente a oxida\u00e7\u00e3o dos grupos hidroxila prim\u00e1rios de polissacar\u00eddeos para convert\u00ea-los em grupos carboxila.<\/h4>\n

3. Contato com o oxidante da rea\u00e7\u00e3o, usado para a oxida\u00e7\u00e3o do iodobenzeno diacetil nerol para produzir nerol. Em resumo, o cobre\/TEMPO \u00e9 usado para a rea\u00e7\u00e3o de contato do \u00e1lcool de 1 posi\u00e7\u00e3o com o alde\u00eddo.<\/h4>\n
