반응 단계
Following the procedure of E. T. McBee et al. ibid, 2-methyl-3,3,4,4,5,5,5-heptafluoro-pentan-2-ol was prepared by adding methyl heptafluorobutyrate to 2 equivalents of methyl Grignard. The alcohol (boiling point 108° C.) was dehydrated with concentrated sulfuric acid to 2-methyl-3,3,4,4,5,5,5-heptafluoro-pent-1-ene (boiling point 55° C.). Hydrogenation of this olefin at 1500 psig using 5% rhodium/carbon gave 2-methyl-3,3,4,4,5,5,5-heptafluoropentane, boiling point 59°-61° C. 1H NMR (CDCl3) δ 1.2 (d, 6 Hz), 2.45 (m). This compound was miscible with silicone oil with a perfluorinated polyether at 25° C. and with light mineral oil at 56° C.
