Реферат:
A comparative assessment is performed of the separation capability of three types of PLOT capillary columns: PTMSP032 (poly(1-trimethylsilyl-1-propyne)), Rt-Q-BOND (polydivinylbenzene), GS-GasPro (silica), and it is studied of the possibility of their use for the determination of impurities in commercial (target, technical) n-butane. Satisfactory separation of alkanes, alkenes, arenes and methanol was achieved on PTMSP032 and Rt-Q-BOND columns. The effect of the main component amount of the mixture on the separation of trace amounts of hydrocarbons and methanol is studied. It is shown that the macrozone (> 99%) of n-butane is selectively separated from the accompanying impurities. With an increase in the injected sample volume, the resolution for the peaks of C1–C2 hydrocarbons and the structural isomers of o-, m-, and p-xylenes on the PTMSP032 column is significantly higher than on the Rt-Q-BOND column. A comparative assessment of the precision of the measurements of the hydrocarbons and methanol retention times on PTMSP032 and Rt-Q-BOND is characterized by a relative standard deviation (RSD) of not more than 0.3%.
