There are 9 isomers of heptane. The normal boiling point of liquid heptane is 371 K 371 K.
Assuming that its molar heat of vaporization is constant at 347 kJmol 347 k J m o l the boiling point of C7H16 C 7 H 16 when the. Heptane boiling point under vacuum. Use the calculators below to find the boiling point andor vapor pressure of a liquid.
Heptane or n-heptane is the straight-chain alkane with the chemical formula H 3 C CH 2 5 CH 3 or C 7 H 16 and is one of the main components of gasoline petrol. Boiling Point C Solvent. Boiling Point C Acetic Acid.
15 rows Point o C Boiling Point o C State at 25 o C. C 2 H 6. Low boiling point.
The heptane boiling point is 9842 degrees Celsius. It cannot be dissolved in water. Heptane has a solubility in water of 00003 at 25C.
On the other hand the solubility of water in heptane is 001 at 25C. It evaporates really slowly. Given that heptane is under a lot of high vapor pressure it doesnt evaporate that.

Heptane is an environmentally preferable solvent and greener alternative to hexane and thus has been enhanced for Safer Solvents and Auxiliaries. Click here for more information. Heptane is a linear hydrocarbon that is considered as a greener alternative to the more toxic hexane.
The heat of evaporation of your substance will be calculated when you ACCEPT these data. This means you can obtain very accurate results now. Take crotonic acid for example.
It boils at 185C under 760 mmHg atmospheric pressure and at 80C under 10 mmHg. The table below lists the boiling points of some alkanes.
