Abstract

"PROCESSOS PARA SEPARAçãO E RECUPERAçãO DE FLUORETO DE HIDROGêNIO, E PARA A PRODUçãO DE UM COMPOSTO ORGâNICO QUE CONTéM FLúOR". Um processo para a recuperação de fluoreto de hidrogênio que compreende o contato de uma mistura gasosa contendo fluoreto de hidrogênio e um composto orgânico com uma solução de um fluoreto de metal alcalino em fluoreto de hidrogênio, separando uma fase gasosa esgotada em fluoreto de hidrogênio e contendo o composto orgânico a partir de uma fase líquida enriquecida em fluoreto de hidrogênio, e em seguida recuperando o fluoreto de hidrogênio a partir da fase líquida.
