Abstract

"PROCESSO PARA A PREPARAçãO DE N-METILDIALQUILAMINAS A PARTIR DE DIALQUILAMINAS SECUNDáRIAS E FORMALDEìDO". A presente invenção refere-se a um processo para a preparação de N-metil-dialquilaminas mediante reação de dialquilaminas secundárias com formaldeído a uma temperatura de 100 até 200<198>C, sendo que para cada mol de dialquilamina secundária são aplicados 1,5 até 3 moles de formaldeído e o produto de reação obtido é desgaseificado, a fase aquosa é separada e a fase orgânica é destilada.
