Abstract: | Summary Iodine numbers by the Hanus and Wijs methods and thiocyanogen numbers using various absorption periods, were determined on
methyl oleate and methyl linoleate and on mixtures of these esters. It is concluded that iodine numbers by the Wijs method
and three-hour thiocyanogen numbers are more satisfactory for methyl linoleate and for mixtures containing large amounts of
this ester.
Small amounts of higher saturated acids were determined with a precision of about 0.1 unit-percent by means of the Bertram
procedure. A purified specimen of methyl oleate was found to contain about 0.2 percent of saturated ester by this method.
