摘要:
Production processes and systems are provided that include reacting halogenated compounds, dehalogenating compounds, reacting alcohols, reacting olefins and a saturated compounds, reacting reactants having at least two -CF3 groups with reactants having cyclic groups. RF-compositions such as RF-intermediates, RF-surfactants, RF-monomers, RF-monomer units, RF-metal complexes, RF-phosphate esters, RF-glycols, RF-urethanes, and/or RF-foam stabilizers. The RF portion can include at least two -CF3 groups, at least three -CF3 groups, and/or at least two -CF3 groups and at least two -CH2- groups. Detergents, emulsifiers, paints, adhesives, inks, wetting agents, foamers, and defoamers including the RF-surfactant composition are provided. Acrylics, resins, and polymers are provided that include a RF-monomer unit. Compositions are provided that include a substrate having a RF-composition thereover. Aqueous Film Forming Foam ('AFFF') formulations are provided that can include RF-surfactants and/or RF-foam stabilizers are provided.
摘要:
Methods and materials are disclosed for the conversion hydrofluorocarbons. More specifically methods and materials are provided for converting hydrofluorocarbons such as HFC-227, HFC-236, HFC-245, HFC-125, HFC-134, HFC-143, HFC-152, HFC-32, HFC-23 and their respective isomers. Methods are provided for converting hydrofluorocarbons such as these to fluoromonomer precursors such as CFC-217, CFC-216, CFC-215, CFC-115, CFC-114, CFC-113, CFC-112, CFC-22, HCFC-22, CFC-12, CFC-13 and their respective isomers. Materials and methods are provided for the conversion of these fluoromonomer precursors to fluoromonomers such as HFP, PFP, TFP, TFE, and VDF.
