Abstract
"PROCESSO PARA A PURIFICAçãO DE FLUOROMETIL HEXAFLUOROISOPROPIL éTER". um processo para a purificação de fluorometil hexafluoroisopropil éter que envolve contatar uma composição bruta de fluorometil hexafluoroisopropil éter e álcool hexafluoroisopropílico com um modificador para modificar a pressão de vapor do éter e/ou do álcool. A diferença em pressão de vapor do éter e do álcool aumenta em relação à diferença em pressão de vapor do éter e do álcool na ausência do modificador e permite a separação do éter do álcool. Apropriadamente, o modificador é amónia ou um amina.
