Abstract
"MéTODO E EQUIPAMENTO PARA A PREPARAçãO DE HIDRAZODICARBONAMIDA UTILIZANDO URéIA COMO MATERIAL DE PARTIDA". Que refere-se a um método e equipamento para a preparação de hidrazodicarbonamida, utilizando uréia como material de partida e, mais particularmente, refere-se a um método e equipamento para a preparação de hidrazodicarbonamida de forma económica e ambientalmente correta através da produção de biureto com uréia e através da reação do biureto obtido com a amónia produzida durante o processo de síntese do biuretoque tem como objetivo prover um método para a preparação da hidrazodicarbonamida de forma economicamente e ambientalmente viável utilizando a uréia, que tem menor custo e pode ser facilmente adquirida como material de partida, sendo que tal método compreende as etapas de: obtenção do biureto da Fórmula 1 e de amónia pela pirólise da uréia; obtenção de sal de monohalobiureto metálico da Fórmula 2 ou 3 pela reação do biureto obtido com um composto de hipohalogênio metálico ou com um halogênio e uma base; e reação do sal de monohalobiureto metálico obtido com a amónia.
