Web15 Sep 2024 · Individual n-alkane standards, C 17, C 18, C 20, C 22, C 24, C 26, C 28 and C 31 were purchased from Sigma Aldrich, UK (purity >99%). Approximately 0.5 g of the individual n-alkane was dissolved in dichloromethane (DCM, purity ≥99.9%; VWR International Ltd, UK) and ultrasonicated for 180 min at 298 K. Webtemperature while their melting points are below room temperature. The lowest molecular mass unbranched alkane that can be a solid at room temperature is octadecane (C18H38 or CH3-(CH2)16-CH3) (m.p. 28°C) and those with more than 18 C's are also solids. You can see that alkane boiling points increase with increasing molecular mass.
