Usage

Uses

Used in the Polymer Industry:
1H,1H,11H-Eicosafluoro-1-undecanol is used as a modifier in polydiene urethane-based composites for enhancing their elastic and strength properties. Its incorporation into these materials leads to improved light-, water-, and thermo-oxidative stability, as well as better diffusion and sorption properties, making the composites more durable and resistant to environmental factors.

Process for hydroxyalkylation of fluorinated alcohols

Mono O-hydroxyalkylated derivatives of 1,1-dihydroperfluorinated or 1H,1-alkylperfluorinated alcohols are prepared by reacting the alcohols with alkylene carbonates at a temperature of at least 60° C. in the presence of a one- or two-part catalyst. The catalyst is a nitrogenous base, optionally in combination with a tetraalkylammonium halide. The O-hydroxyalkylated derivatives are useful non-ionic surfactants and emulsifiable compounds for fire extinguishing systems.
