Ueber die Hydrierung geschlossener Ringe

Abstract: In seiner Arbeit: ,,Ueber die physikalischen Eigenschaften cles Benzols" kam H o r s t n i a n n l ) zu dem Schlusse, das Benzol stehe nach seinen physikalischen Eigenschaften in der Mitte zwischen den gesattigten und ungesattigten Verbindungen der Pettreihe, das Lichtbrechungsvermogen, die Dichte wiesen ihm seine Stellung bei den ungesattigten an , die Verbrennungswarme verhalte sich dagegen wie bei den gesattigten Verbindungen.Zn der Zeit, als diese Arbeit geschrieben wurde, lagen nur Bestimmungen des Warmew… Show more

“…Data on n-hexane were reported by Stohmann, Kleber, and Langbein [36] in 1891, by Zubow [37] in 1898, and by Jessup [30] in 1937, and on 2,3-dimethylbutane by Thomsen [38] in 1886. Since no one investigator measured both isomers, and since the older work of Stohmann et al, Zubow, and Thomsen carries uncertainties as large as several kilocalor;ies per mole, any values deduced from these data for the heat of isomerization of n-hexane into 2,3-dimethylbutane would have uncertainties as large as, or larger than, the heat of isomerization itself.…”

“…Measurements of the heat of combustion of liquid n-hexane by means of a bomb calorimeter were made by Zubow [24], and by Stohmann, Kleber, and Langbein [21]. Zubow reported the value 11602.6 calories per gram weighed in air for the heat of combustion at 18° C under the conditions of the bomb process.…”

“…Stohmann, Kleber, and Langbein [21] made two measurements of the heat of combustion of liquid n-hexane at about 15° C and under an initial oxygen pressure of 24 atmospheres. The volume of their bomb was 294 cm 3 • Combustible impurities were removed from the oxygen by passing it through a red-hot copper tube.…”
