measurements were performed in the temperature
range from 20 to 50°C with 10°C increment using a
UTU-3 ultrathermostat (Poland, the temperature
setting and maintaining precision ±0.1°C).

Gas-chromatographic analysis was performed on a
Tsvet-100 chromatograph with a flame ionization
detector and a packed column I in the mode of
programming temperature from 50 to 220°C at the rate
4–6 deg min–1. In the case of overlapping the signals of
examined components with the peak of a solvent was
used column II in the same mode of temperature
programming: column I: 3 m × 3 mm with 5% SE-30
on Chromaton N (0.16–0.20 mm); column II: 1.5 m ×
3 mm with 20% Carbowax 20M on Chromaton NAW
HMDS (0.20–0.25 mm).

Evaporator temperature 220°C, carrier gas nitrogen
(30 ml min–1), sample dosage 2 μl (microsyringe MSh-
10). Registration of chromatographic peaks (scale
100×10–10 Å) was performed using a TR 2213
integrator (Japan) or a software package UniChrom
(Minsk, version 4.x-5). For monitoring changes in the
mutual solubility of perfluorodecalin and acetonitrile
by the method [11] column I was used at 50°C. Under
these conditions almost complete separation of trans-
and cis-isomers of perfluorodecalin was achieved
(ratio 55: 45; peak areas were summed up), the ratio
obtained is consistent with the typical ratio of trans-
and cis-isomers of this substance according to
published data (~1:1) [21] .
