Abstract

"PROCESSO PARA FORMAçãO DE HIDRAZIDAS E SEUS DERIVADOS A PARTIR DE HIDRAZINAS E áCIDOS DICARBOXìLICOS". A presente invenção fornece um processo para formação de hidrazidas a partir da reação de uma hidrazina com um ácido dicarboxílico, sendo empregado um ácido de Lewis como reagente chave do processo reacional. A reação se passa em um ambiente reacional seguro, empregando condições brandas, não envolvendo a utilização de altas pressões ou temperaturas, produzindo os produtos desejados com rendimentos elevados, em torno de 90-95%. A invenção também fornece um kit de utilização de substâncias quimioluminescentes, sendo tal kit constituído por duas soluções.
