  Gas-chromatographic identification of products formed in iodination of methyl phenols by retention indices

  摘要：

  Iodination reaction followed by conversion of iodine-substituted methylphenols to the corresponding trifluoroacetates was suggested for improving the sensitivity of the gas-chromatographic determination of phenol and its methyl-substituted derivatives (al isomers of mono-and diethylphenols, 2,3,5-, 2,3,6-, and 3,4,5-trimethylphenols) in aqueous media. Acylation products of iodo methylphenols (104 compounds) were identified by linear-logarithmic retention indices on a standard nonpolar polydimethylsiloxane stationary phase, and the pattern of their variation with the number and nature of substituents were characterized. A procedure for identification of methyl-substituted phenols in water in their gas-chromatographic determination with an electron-capture detector was developed.

  The present invention relates to liquid-crystalline media comprising more compounds of formula Q and one or more compounds selected from the group of compounds of formulae T, U and I wherein the occurring groups and parameters have the meaning indicated in claim 1. The present invention further relates to the use of these liquid- crystal media, in particular in components for high-frequency technology, and to components of this type which contain media according to the invention, and to the production and use of these components. The components according to the invention are suitable, in particular, as phase shifters in the microwave and millimetre wave region, for microwave and millimetre wave array antennae and very particularly for so-called tunable "reflect- arrays".
