Abstract

"PROCESSO PARA A PREPARAçãO DE áCIDO METACRìLICO DE ALTA PUREZA, áCIDO METACRìLICO DE ALTA PUREZA, E, METODOS PARA IMPEDIR A DECOMPOSIçãO DE HIBA DENTRO DE UMA CORRENTE CONTENDO áCIDO METACRìLICO E UM CATALISADOR áCIDO, PARA REMOVER HIBA DE UMA CORRENTE CONTENDO áCIDO METACRìLICO E PARA PURIFICAR UMA CORRENTE DE MAA CONTENDO HIBA EM UM PROCESSO DE PURIFICAçãO". é fornecido um processo neste relatório para a produção de alto rendimento de ácido metacrílico glacial de alta pureza ('HPMAA') que seja substancialmente puro, especificamente 99% puro ou mais, com teor de água de 0,05% ou menos e baixos níveis de outras impurezas, incluindo HIBA, ácido acrílico, MOMPA, metacroleína e outros. Este processo melhorado compreende o fornecimento de uma corrente de MAA bruto e a purificação da corrente de ácido metacrílico bruto em uma série de etapas sucessivas de destilação envolvendo duas colunas de destilação. O processo da invenção é capaz de produzir o produto de ácido metacrílico de alta pureza que seja especialmente adequado para a produção de polímeros de MAA especiais.
