  • Trans-1, 2-dichloroethylene and hydrofluorocarbon or alkoxy perfluoroalkane compositions having elevated flash points
    Publication number: 20070010421
    Abstract: A tran-1,2-dichloroethylene blend which comprises a combination of a major amount of tran-1,2-dichloroethylene and a minor amount of a hydrofluorocarbon or an alkoxy perfluoroalkane having an elevated flash point is disclosed. The combination exhibits a flash point significantly higher than trans-1,2-dichloroethylene alone while containing only a minor amount of the component exhibiting the high Global Warming Potential. The preferred hydrofluorocarbon is 1,1,1,2,2,3,4,5,5,5-decafluoropentane or 3,3,4,4,5,5,6,6,6-nonafluoro-1-hexene and the preferred alkoxy perfluoroalkane is 1-(methoxy)nonafluorobutane.
