    Abstract: Disclosed are compositions and methods for cleaning contaminated articles based on the provision of a zeotropic composition comprising (a) at least one flammable solvent having a boiling point at a first pressure; (b) at least one first nonflammable solvent having a boiling point at said first pressure which is less than about said first pressure boiling point of said flammable solvent; and (c) at least one second nonflammable solvent having a boiling point at said first pressure which is greater than about the first pressure boiling point of said flammable solvent.

    Abstract: Disclosed is an integrated process to co-produce trans-1-chloro-3,3,3-trifluoro-propene (1233zd(E)), trans-1,3,3,3-tetrafluoropropene (1234ze(E)), and 1,1,1,3,3-pentafluoropropane (245fa). Overall the co-production is a three-step process. The chemistry involves the steps of: (1) the reaction of 240fa with anhydrous HF in excess in a liquid-phase catalyzed reactor in such a way as to co-produce primarily 1233zd(E) and 244fa (plus byproduct HCl); (2) the 244fa stream can then be used to directly produce any of the three desired products; (3a) the 244fa stream can be dehydrochlorinated to produce the desired second product 1234ze(E); and/or (3b) the 244fa stream can be dehydrofluorinated to produce 1233zd(E) if more of that product is desired; and/or (3c) the 244fa stream can be further fluorinated to form 245fa.
