N-heptan siedetemperatur Heptan ist ein kettenförmiger Kohlenwasserstoff aus der Stoffgruppe der Alkane mit der Summenformel C₇H₁₆. Er ist der unverzweigte Vertreter der neun Heptan-Isomere. Heptan ist entzündlich und wassergefährdend. 1 l−1 bei 25 °C) · löslich in. 2 Die neun Heptan-Isomere haben folgende Siedepunkte: n-Heptan: 98 ºC, 2-Methyl-hexan: 90 ºC, 3-Methyl-he- xan: 92 ºC, 2,2-Dimethyl-pentan: 79 ºC. 3 Molmasse , g/mol ; AGW ml/m3 (TRGS ) ; Dichte 0, g/cm ; Schmelzpunkt −90, °C ; Siedepunkt +98,38 °C. 4 n-Heptane is defined as the zero point of the octane rating scale. It is a lighter component in gasoline, burns more explosively, causing engine pre-ignition (knocking) in its pure form, as opposed to octane isomers, which burn more slowly and give less knocking. 5 IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters ( feet) in all directions. LARGE SPILL: Consider initial downwind evacuation for at least meters ( feet). FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for meters (1/2 mile) in all directions; also, consider initial. 6 n-Heptane: Übersicht: EMSURE® grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE® provides worldwide best and most extensive product specifications. 7 n-Heptane MSDS (material safety data sheet) or SDS, CoA and CoQ, dossiers, brochures and other available documents. SDS.

Ph Eur. 8 The low temperature chemistry of n-heptane is dominated by consecutive oxygen addition pathways, which lead to oxygenated reaction products [8]. In Section , several oxygenated species, i.e. C 7 H 12 O 2, C 7 H 14 O, and C 7 H 14 O 3, were identified, and their temperature-dependent signal profiles are shown in Fig. 5 with the associated. 9 l −1 bei 25 °C) [2] löslich in vielen organischen Lösungsmitteln wie Ethanol, Testbenzin, Benzol oder Tetrachlormethan [3] Brechungsindex. n-heptan sicherheitsdatenblatt 10 heptan isomere 12
