Sažetak
Determination of methoxyl and ethoxyl groups in organic compounds according to Zeisel 's method frequently yielded somewhat higher analytical values. This usually occured when the methyl or ethyl iodide was insufficiently purified from matters which hindered their determination. Liquid-filled washers are used for the elimination of these matters. When the liquids in the washer were replaced by solid ascarite, and the determination carried under a stream of nitrogen or air, no errors occurred . Besides, if a layer of anhydrone was added to the washer containing ascarite, the carbon and hydrogen content of the obtained methyl or ethyl iodide could be determined, and it could thus be ascertained whether the organic compound contained methoxyl groups, ethoxyl groups, or a mixture of both.
