摘要:
Disclosed are compositions comprising 90 to 99 weight percent trans-1,2-dichloroethylene, from 0.1 to 8 weight percent methylperfluoroheptene ethers and from 0.1 to 2.0 weight percent of 1,1,1,2,2,3,4,5,5,5-decafluoropentane, wherein the composition is non-flammable. The disclosure further provides a method for removing residue from a surface of an article comprising: (a) contacting the article with a composition comprising a composition of MPHE, HFC-4310mee and trans-1,2-dichloroethylene; and (b) recovering the surface from the composition.
摘要:
The present disclosure provides, in part, a solvent composition including an an acetic acid alkyl (C1-C4) ester (e.g., methyl acetate (MA), ethyl acetate (EA), or tert-butyl acetate (TBAc)) and a carbonate ester (e.g., dimethyl carbonate, or propylene carbonate).
摘要:
The invention relates to certain compositions of hydrofluoroalkanes, hydrofluoroalkenes, hydrofluoroethers or hydrofluoroketones with 1,2-dichloroethylene and fatty acid esters as well as mixtures comprising these compositions and the use of the same especially as cleaning and/or drying agents for solid surfaces and for flushing, especially of refrigeration systems.

摘要:
This invention provides a heat transfer composition comprising from about 5 to about 40 % by weight of trans -1,3,3,3-tetrafluoropropene (R-1234ze(E)), from about 20 to about 35 % by weight difluoromethane (R-32), from about 15 to about 30 % by weight R-125 pentafluoroethane (R-125), and from about 12 to about 50 % by weight 1,1,1,2-tetrafluoroethane (R-134a).
