Abstract

"PURIFICAçãO DE 2-METóXI-5-TRIFLUOROMETOXIBENZALDEìDO". Um processo para a purificação do óleo 2-metóxi-5-trifluorometoxibenzaldeído no qual o óleo é convertido em amina por reação de uma nitroanilina com o óleo; a imina é isolada na forma de um sólido; e a imina sólida é de novo convertida para o óleo 2-metóxi-5-trifuorometoxibenzaldeído. A nitroanilina é selecionada a partir do grupo consistindo em 3-nitro-anilina, 3-metil-2-nitroanilina, 4-metil-2-nitroanilina, 2-metil-3-nitroanilina e 4-metil-3-nitroanilina.
