Gas‐chromatographische Charakterisierung organischer Verbindungen. Teil 3: Berechnung der Retentionsindices aliphatischer, alicyclischer und aromatischer Verbindungen.

Abstract: Volumen XLII, Fasciculus VII (1959) -No. 291 -292 2709 c yclen abgeklart werden. Durch die Synthese der optisch aktiven A l*lob-N-Mct hylhexahydro-benzo[f]chinolin-2-one und der entsprechenden Alkoholbasen liess sich auf Grund der bereits bekannten, relativen Konfiguration an den beiden Asymmetriezentren der Lysergsauren, wiederum durch spektropolarimetrischen Vergleich, die absolute Konfiguration der vier isomcren Lysergsauren, insbesondere am asymmetrischen Kohlenstoffatom c-5, ableiten.Physikalisch-chemis… Show more

“…Atropine was used as internal standard. Retention indices (RIs) were calculated from cochrom atographed hydro carbon standards according to [11]. GC-MS: A Carlo Erba Mega 5160 gas chrom atograph equip ped with a quartz column (30 m x 0.32 mm) speci fied as given above, was directly coupled to a quadrupole mass spectrometer Finnigan MAT 4515.…”

“…Os tempos de retenção das parafinas padrões utilizadas para o cálculo dos índices de retenção [27][28][29][30][31][32][33][34][35] foram obtidos através da injeção de uma amostra padrão de nafta (Quantitative Reference Naftha Standart, 4-8265-U-Supelco). A Tabela 1 apresenta a composição da gasolina base com massa molar média de 107 g mol -1 e fórmula molecular média C 8 H 15 .…”

“…An effective back-calculated solute dipolarity value would be an improvement over r*2, and other replacement terms were also investigated. Attempts would also t -made to replace the trivial parameter 62 with a parameter that could more accurately represent the degree of solute dipolarisability. This parameter should ideally be easily calculated and have some sort of rationale behind it.…”
