Abstract

"PROCESSOS PARA A PRODUçãO DE ACETAIS A PARTIR DA REAçãO DE ALDEìDOS COM áLCOOL E PARA A PRODUçãO DE METILAL A PARTIR DA REAçãO DE FORMALDEìDO COM METANOL" Acetais são produzidos pela reação de aldeídos e álcoois, por exemplo pela reação de metanol com formaldeído, pela reação em uma coluna de destilação de reação de álcool e aldeído na presença de um catalisador e a destilação fracionada concorrente da mistura reacional para separar os produtos de reação, água e acetal.
