WebIt looks like you might have flipped the two concepts. Branching of carbon compounds have lower boiling points. An example of this would be neopentane - C(CH3)4 - which has a boiling point of 282.5 Kelvin and pentane - CH3CH2CH2CH2CH3 - which has a boiling point of 309 Kelvin. Pentane has the straight structure of course.

WebJan 21, 2024 · In the liquid phase, fumaric acid will keep the near-sphere ordering somewhat intact, i.e. conserve a high number of hydrogen bonds to its neighbours. However maleic acid will probably stick with one fully intramolecular hydrogen bond that does not contribute to intermolecular attractions, thereby lowering its boiling point. WebSome crude oils contain components of high boiling-point that are difficult to recover even when high vacuum is used. Such materials are therefore separated from the vacuum residue using solvent precipitation, usually with propane or butane. ...

WebDec 31, 2024 · It is the heaviest fraction and the one with the highest boiling point, boiling at 525 °C (977 °F). What is the softening point of bitumen? The softening point value of the two readings should not exceed 1.0 °C for the softening point of bitumen range 40-60 °C and 1.5 °C for the softening point between 61-80 °C. laws of integration
