Die Bestimmung der Hydrierjodzahl und ihre Anwendung bei der Analyse des Essangöls (Studien auf dem Fettgebiet, 45. Mitteil.)

Thermolysis of N‐oxides of some o‐dimethylaminoalkyl derivatives of cellulose

“…Double bonds were determined by the addition of bromine [3]. DEAE-Sephadex (Pharmacia, Sweden) and 0-(2-aminoethy1)cellulose (AE-50, Whatman, England) were used as supplied.…”

Simplified Microhydrogenation Apparatus

“…Their apparatus, however, was designed for semimicroquantities of material, as were those of Erdos (S), Zechmeister and von Cholnoky (17), and Mayeda (10). Kaufmann and Baltes (8) devised an apparatus on this same principle for determination of the degree of unsaturation of fats by catalytic hydrogenation, using 20-to 40-mg. samples. Weygand and Werner (16) used an electromagnetic stirring device in their apparatus.…”

A critical study of the precision and value of halogen addition reactions applied to dairy research

“…Bromine vapor has been employed by the following jjivestigators; Becker (9), Toms (82,a^), Bbeseken and Polls (15), f/ollschitt (95) and Rossman (71,72), Biilmann (10) studied the action of bromine water on unsaturated compounds, Kaufmann (40) found that thiocyanogen could be used to determine simple ethylenic linkages. A catalytic hydrogenation method, the results of wMch are calculated in tenas of iodine number, was described by Kaufmann and Baltes (46).…”
