Abstract:
Capillary columns based on a number of thermostable polysiloxane–silarylene motionless phases are prepared and their properties are studied. Three polymers with different contents of methyl and phenyl groups are synthesized: dimethylsiloxanesilarylene (DMS), methylphenylsiloxanesilarylene (MPhS), and diphenylsiloxanesilarylene (DPhS). Studies of their thermostability show that the level of the background current of these columns upon heating to 350°С is several times lower than that of a column based on polydimethylsiloxane. Based on McReynolds’ studies of polarity and Abraham’s studies of the selectivity of prepared columns according to the parameters of intermolecular interactions, it is found that silarylene MLPs are more affected by the contributions from specific interactions (especially for dipole-dipole, π–π-, and n–π-interactions) than MLPs with no phenylеne inserts. The effect on the selectivity of a phenyl group inside a chain differs from the one produced by the phenyl groups in side MLP chains. The effect on the selectivity of a phenyl group inside a chain differs from the one produced by the phenyl groups in side MLP chains. Examples of the separation of test mixtures of aromatic and oxygen-containing compounds are obtained, along with an extract of thistle oil containing tocopherols and phytosterols at a final temperature of analysis of 350°С.
