ETIMOLOGIA DA PALAVRA MOND PROCESS
Named after Ludwig Mond (1839–1909), German chemist and industrialist.
O QUE SIGNIFICA MOND PROCESS EM INGLÊS
Processo Mond
O processo de Mond, às vezes conhecido como o processo carbonílico, é uma técnica criada por Ludwig Mond em 1890 para extrair e purificar o níquel. O processo foi usado comercialmente antes do final do século XIX. Este processo converte os óxidos de níquel em níquel puro. Este processo faz uso do fato de que os complexos de monóxido de carbono com níquel são prontamente e reversivelmente para dar carbonilo de níquel. Nenhum outro elemento forma um composto de carbonilo sob condições suaves usadas no processo. Este processo tem três etapas: 1. O óxido de níquel é feito reagir com Syngas a 200 ° C para remover o oxigênio, deixando o níquel impuro. As impurezas incluem ferro e cobalto. NiO + H2 → Ni + H2O 2. O níquel impuro é feito reagir com excesso de monóxido de carbono a 50-60 ° C para formar o gás níquel carbonilo, deixando as impurezas como sólidos. Ni + 4 CO → Ni4 3. A mistura de excesso de monóxido de carbono e níquel carbonilo é aquecida a 220-250 ° C. Ao aquecer, o tetracarbonilo de níquel decompõe-se para dar níquel: Ni4 → Ni + 4 CO. A decomposição pode ser projetada para produzir pó, mas, mais comumente, um substrato existente é revestido com níquel.
definição de Mond process no dicionário inglês
A definição de processo de Mond no dicionário é um processo para a obtenção de níquel por aquecimento do minério em monóxido de carbono para produzir vapor de carbonilo de níquel, o qual é então decomposto a uma temperatura mais alta para produzir o metal.
