The dielectric constant and loss data, measured at seven microwave frequences, for seventeen aliphatic esters in cyclohexane solution at 2YC have been analyzed for mean relaxation times and Cole-Cole distribution parameters. The relaxation times for ethyl esters are slightly longer than those for corresponding methyl esters. In both cases, however, the relaxation time does not lengthen significantly as R in RCOOR' is increased from C 5 to C n . It would appear that the dielectric absorption of aliphatic ester…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
