Abstract

Production processes and systems are provided that include reacting halogenated compounds, dehalogenating compounds, reacting alcohol's, 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 groups —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.
