With the use of quartz capillary columns with a non-polar and a polar
stationary liquid phase (SLP), a chromatographic analysis has been mad
e of high-boiling products of alkylation of mono- and dihydric phenols
by styrene. The time of analysis can be shortened, while retaining a
high efficiency of separation, by using a short capillary column with
polar liquid phase PEG-20M. The degrees of retention on the two SLPs h
ave been determined, and a correlation relationship has been obtained
which confirms the reliability of identification of the compounds anal
ysed.
