Abstract
"PROCESSOS PARA SEPARAçãO DE UM PRODUTO CONTENDO FORMALDEìDO DE UMA SOLUçãO DE FORMALDEìDO E PARA A PRODUçãO DE METACRILATO DE METILA, E; PRODUTO CONTENDO FORMALDEìDO". Um processo para separação de um produto contendo formaldeído de uma solução de formalina compreendendo formaldeído, água e metanol, no qual citado produto contendo formaldeído contém substancialmente menos água do que citada solução de formalina, compreendendo destilação da citada solução de formalina na presença de um composto de arraste de água, especialmente propionato de metila ou metacrilato de metila. O produto contendo formaldeído é adequado para uso em um outro processo que requer uma fonte de formaldeído contendo um nível de água relativamente baixo. Um exemplo de um tal processo é a reação de propionato de metila com formaldeído e metanol sobre um catalisador para produzir metacrilato de metila.
