Abstract

"PROCESSO PARA PRODUçãO DE COMPOSTO DE OXIRANO". A invenção refere-se a um processo para produção de um composto de oxirano a partir de um peróxido orgânico diferente de hidroperóxido de etilbenzeno e de uma olefina na presença de um leito de catalisador imobilizado, processo este que satifaz as seguintes condições (1) a (4): (1) o leito de catalisador é dividido em n leitos de catalisador e os leitos de catalisador são usados em série, em que n é um número inteiro de 2 ou mais, (2) um peróxido orgânico novo é dividido em porções, que são alimentadas a respectivas entradas dos leitos de catalisador, (3) uma olefina nova é alimentada à entrada do primeiro leito de catalisador, e (4) a mistura reacional descarregada de cada saída dos respectivos leitos de catalisador, excluindo o leito final de catalisador, é alimentada à entrada do leito de catalisador subseq³ente.
