Abstract

Patente de Invenção: <B>"PROCESSO APERFEIçOADO PARA PREPARAçãO DE 4-AMINO-1,2,4-TRIAZOLIN-5-ONAS"<D>. A presente invenção refere-se a um processo aperfeiçoado para a preparação comercial de aminotriazolinas substituídas, que são intermediários conhecidas na preparação de compostos herbicidas ativos. Em particular, esta invenção se refere à preparação de 4-amino-1,2,4-triazolin-5-onas e, mais particularmente, à preparação de 3-isopropil-4-aminotriazolinona. O processo da invenção inclui a reação de uma oxadiazolinona com hidrato de hidrazina, na ausência de um solvente. Em uma concretização preferida, o hidrato de hidrazina é misturado com um composto básico, de preferência, hidróxido de sódio aquoso.
