Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 2043-47-2, name is 1H,1H,2H,2H-Nonafluoro-1-hexanol. This compound has unique chemical properties. The synthetic route is as follows. Computed Properties of C6H5F9O
To a mixture, kept under stirring, of C4F3CH2CH2OH (200 g, 0.757 moles), tetrahydrofurane (350 ml) and cyclohexane (300 ml) at 250C, an aqueous solution of NaOH (400 ml, 50%) was added drop-wise. After stirring for 2 hours, benzyltriethyl ammonium chloride (25 g, 0.11 moles) as phase transfer catalyst, and then 1- bromopropane (170 g, 1.38 moles) were added. The reaction mixture was kept under stirring at 400C for 40 hours, then at 700C for 8 hours. The resulting mixture was poured into water and the organic phase thus obtained was washed two times with water. After removing the fraction having a low boiling point, the raw product was subjected to distillation at reduced pressure, ? thus obtaining 200 g of C4F9CH2CH2O (CH2) 2CH3 (yield 86%, boiling temp. 1470C, n 1.3255) . Spectrographic data confirm the obtained structure: GC/MS m/z at 305 (M- H)+, 377 (M-CH2CH3J+, 73 ( -CH2OCH2CH2CH3) +, 43 (- CH2CH2CHj) + ; for NMR data see Tables 1-2.
