Reaction Steps
The precursor, C8H17OCH2OC4H8OH was prepared by monoalkylation of butane diol with octyl chloromethyl ether. The precursor was first acetylated with acetyl chloride in methylene chloride containing triethylamine and then fluorinated, and a portion of the crude perfluorinated product was hydrolyzed by treatment with aqueous sulfuric acid and then distilled to yield the carboxylic acid C8F17OCF2OC3F6CO2H, having a boiling range 100°-106° C. at 1.1 torr. Differential scanning calorimetry revealed the acid had a Tg of -97.0° C. and several crystalline exotherms of -77.4, -61.5 and -37.7° C. and a broad melting point at -9.0° C.
