초록

An azeotropic composition includes a perfluorinated cycloaminoether and an organic solvent.

대표
청구항

[ What is claimed is:] [1.] An azeotropic composition consisting essentially of about 50 to 40 weight percent perfluoro-N-methyl-morpholine and about 50 to 60 weight percent 1-fluoro-1,1- dichloroethane, which when fractionally distilled, produces a distillate fraction that is an azeotrope of perfluoro-N-methyl-morpholine and 1-fluoro-1,1-dichloroethane that boils at about 27.degree. C. at atmospheric pressure.
