307-70-0 Usage
Uses
1H,1H,11H-Eicosafluoro-1-undecanol is a highly fluorinated alcohol, and has been used as a modifier in polydiene urethane-based composites, increasing elastic and strength properties, light-, water- and thermo-oxidative stability, and diffusion/sorption properties.
Check Digit Verification of cas no
The CAS Registry Mumber 307-70-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,0 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 307-70:
(5*3)+(4*0)+(3*7)+(2*7)+(1*0)=50
50 % 10 = 0
So 307-70-0 is a valid CAS Registry Number.

Process for hydroxyalkylation of fluorinated alcohols
-
, (2008/06/13)
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.
