Abstract

The measurement of unsaturation in organic compounds are commonly expressed in terms of an iodine number, but as this value is not trustworthy in a number of cases, it has been suggested by earlier worker that an indication of unsaturation could be obtained by the quantitative hydrogenation of a compound and expressing the result in terms of a hydrogen number. Although such determinations have been previously made, usually at elevated temperatures and pressures, it is the purpose of this work to carry out the hydrogenation at room temperature and atmospheric pressure. For purposes of comparison, determinations will be made at temperatures of approximately 40°c and 70°C. The compound to be examined for the purpose of establishing the validity of the method to be used is 9-10 oleic acid since the iodine values of this compound· and its hydrogenated products do give a trustworthy measurement of unsaturation. Thus, iodine numbers can be used to measure the success of the hydrogenation. Solutions of the oleic acid in ethyl alcohol, normal propyl alcohol, ethyl acetate, chloroform, carbon tetrachloride, and cyclohexane are to be used and compared.
