le spectre rmn du 19 f du dérivé diéthyléné est identique à celui du monoéthyléné.
[0296] the nmr spectrum of the 19 f of the diethylenated derivative is identical to that of the monoethylenated one.

après distillation, on récupère d'abord le dérivé monoéthyléné, l,4-dibromo-2-chloro-l,l,2-trifluorobutane, (brcf 2 cfclc 2 h 4 br), incolore (t eb = 59-62 °c / 20 mm hg) puis le diéthyléné, 1 ,6-dibromo-2-chloro- 1 , 1 ,2-trifluorohexane, (brcf 2 cfclc 4 h 8 br) incolore (t eb = 50-53 °c / 0,8 mm hg).
after distillation, first of all the colourless mono-ethylenated derivative, 1,4-dibromo-2-chloro-1,1,2-trifluorobutane (brcf 2 cfclc 2 h 4 br), (t eb =59-62° c./20 mm hg), then the colourless diethylenated derivative, 1,6-dibromo-2-chloro-1,1,2-trifluorohexane (brcf 2 cfclc 4 h 8 br) (t eb =50-53° c./0.8 mm hg), is recovered.
