Title: Processo para a preparação de acetato de etila
Inventor: COLLEY STEPHEN WILLIAM
IPC: C07B61/00
Filed: 1999-09-29
Abstract: Patente de Invenção: <B>"PROCESSO PARA A PREPARAçãO DE ACETATO DE ETILA"<D>. Etanol é desidrogenado na presença de hidrogênio sobre um catalisador de desidrogenação, por exemplo, um catalisador de cobre sobre sílica. Os produtos que podem ser liquefeitos presentes na mistura do produto da reação intermediário resultante são hidrogenados seletivamente sobre um catalisador adequado, tal como rutênio a 5% sobre carbono, de modo a hidrogenar seletivamente subprodutos reativos que contém carbonila aos álcoois correspondentes. Butan-2-ona e <MU>n<MV>-butiraldeído, que de outra forma causariam dificuldades na purificação do produto acetato de etila, em virtude da proximidade de seus pontos de ebulição ao do acetato de etila, são desse modo hidrogenados a 2-butanol e a <MU>n<MV>-butanol respectivamente. é então usado um procedimento de destilação em dois estágios para purificar o produto hidrogenado seletivamente. A primeira zona de destilação é tipicamente operada a menos do que aproximadamente 4 bar (4 x 10^ 5^ Pa) absolutos, enquanto que a segunda zona de destilação é tipicamente operada a uma pressão de desde aproximadamente 4 bar (4 x 10^ 5^ Pa) absolutos até aproximadamente 25 bar (2,5 x 10^ 6^ Pa). Um primeiro destilado de acetato de etila, etanol e água produzido na primeira zona de destilação é redestilado na segunda zona de destilação, produzindo dessa maneira um produto de fundo que compreende, tipicamente, desde aproximadamente 99,8% em mol até aproximadamente 99,95% em mol de acetato de etila e um segundo destilado de topo, que tem uma composição diferente daquela produzida na primeira zona de destilação e que é retornado para a primeira zona de destilação, de preferência a um ponto acima do ponto de alimentação para os produtos que podem ser liquefeitos da mistura do produto da reação hidrogenado seletivamente.
