Abstract

"PROCESSOS PARA A CONDENSAçãO FRACIONADA DE UMA MISTURA GASOSA E PARA A PREPARAçãO DE áCIDO ACRìLICO OU áCIDO METACRìLICO" A invenção refere-se a um processo para a condensação fracionada de uma mistura gasosa, que contém pelo menos um outro constituinte condensável, em adição ao ácido acrílico ou ácido metacrílico, e que possui também uma alta proporção de um ou mais constituintes não condensáveis. De acordo com o referido processo, a mistura gasosa é passada através de um coluna com chicanas eficientes para a separação e os constituintes condensáveis são condensados por resfriamento.
