Fluorinated telomer alcohol

The so-called telomer alcohols are fluorinated79 over cobalt(III) fluoride at 180°C, e.g. fluorination of 1. 

Greiner et al. [152] prepared fluorinated ether sulfates, H-(CF2CF2) CH2 [0CH2CH2], 0S03NH4, n = 2, 3, 4, m = average 3. The telomer alcohols were oxyethylated using BF3 as the catalyst, sulfonated with chlorosulfonic acid, and neutralized with ammonia. 

The preparation of nonionic fluorinated surfactants from fluorinated alcohols is straightforward [218-230]. Perfluoroalkylethanol (see Section 2.3), obtained from telomer perfluoroalkylethyl iodides, is oxyethylated in the presence of a catalyst, for example, BF3 ... 

Telomer B alcohol [4]. Scotchgard FC-1395, a fluorinated polymer, was made by 3M [5]. The fluorinated soil retardant is undoubtedly the most important component of the soil and stain-resist finish on the carpet because soiling by foot traffic is a daily occurrence, whereas staining with liquids is an accidental event.
