Abstract

PROCESSO PARA A PREPARAÇçO DE ALCOOLATOS DE METAL ALCALINO. A presente invenção refere-se a um processo para a preparação de uma solução alcoólica de um alcoolato de metal alcalino a partir de hidróxido de metal alcalino e álcool, em uma coluna de reação, sendo que o álcool e o hidróxido de metal alcalino são conduzidos em contracorrente, caracterizado pelo fato de que a proporção de refluxo é ajustada em pelo menos 0,05 na coluna de reação.
