CAPILLARY GAS CHROMATOGRAPHY OF HIGHER ALKYLPOLYOXYETHYLENE GLYCOLS WITH AN EVEN NUMBER OF CARBON ATOMS IN THE ALKYL GROUP - INFLUENCE OF TYPE OF DERIVATIZING AGENT, ALCOHOL CHAIN LENGTH AND OXYETHYLENE CHAIN LENGTH ON THE RETENTION INDICES WITH A LI

摘要

The influence of an increase in the length of the chain in the alkyl or polyoxyethylene glycol part of molecule of some homologous series of higher alkylpolyoxyethylene glycols and their derivatives on retention indices with a linear temperature increase was studied. The influence of the functional group supplied by the derivatizing agent on the retention index was also studied. Alkylpolyoxyethylene glycols with an even carbon number were converted by derivatization reactions into acetates, monochloroacetates, trifluoroacetates and trimethylsilyl ethers.
