Boiling Point Of Butanol. The boiling point of n-butanol is 117 o C. For example ethanol with a molecular weight MW of 46 has a boiling point of 78 C 173 F whereas propane MW 44 has a boiling point of 42 C 44 F. In mice after a single ip injection of 81 mmol tert-butanolkg body weight initial blood levels of 8 mmol took 8-9 hr for elimination blood- tert-butanol half-life was approximately 5 hr. This is significant in cooling the car since as soon as the water in the car radiator boilsit does not work anymore as a coolant.

Caesium 40 o C 980. The definition of boiling point states that it is the temperature when the vapor pressure of the compound equals to the atmospheric pressure. Near the boiling point of the solvent. N-butanol CH3CH2CH2CH2OH 8 n-pentanol CH3CH2CH2CH2CH2OH 2 n-hexanol CH3CH2CH2CH2CH2CH2OH 05 n-pentanol CH3CH2CH2CH2CH2CH2CH2OH 01 Compounds with six or more carbons for each polar group will not be very soluble in polar solvents but will be soluble in non. But the boiling point of sodium butoxide is higher than that of butanol because the attractive force in sodium butoxide is very strong ionic bond. Ethane -886 o C 1316.
Exposure to an air concn of 50 ppm for 2 hr resulted in blood levels less than 008 mgl.
Making butanol from oil produces no such odour. Such a large difference in boiling points indicates that molecules of ethanol are attracted to one another much more strongly. 1-Butanol 20 o C 1262. We mentioned in the previous post that stronger intermolecular interactions increase the boiling and melting points but how exactly they affect the physical properties might be your next question. It is one of several isomers of amyl alcohol pentanol. Small amount of compound being purified should remain in solution at low temperatures.

But the boiling point of sodium butoxide is higher than that of butanol because the attractive force in sodium butoxide is very strong ionic bond. Butanols only major disadvantages are its high flashpoint 35 C or 95 F toxicity note that toxicity levels exist but are not precisely confirmed and the fact that the fermentation process for renewable butanol emits a foul odour. Chlorobenzene 25 o C 1270. Making butanol from oil produces no such odour. N-butanol CH3CH2CH2CH2OH 8 n-pentanol CH3CH2CH2CH2CH2OH 2 n-hexanol CH3CH2CH2CH2CH2CH2OH 05 n-pentanol CH3CH2CH2CH2CH2CH2CH2OH 01 Compounds with six or more carbons for each polar group will not be very soluble in polar solvents but will be soluble in non.

Such a large difference in boiling points indicates that molecules of ethanol are attracted to one another much more strongly. The freezing point depression aspectcan also be applied in daily life for example in raising the boiling point of the water that cools cars. Chlorobenzene 25 o C 1270. Cyclohexane 20 o C 1280. Antifreeze decreases the freezing point and increases the boiling point of thecoolant water in the car radiator.
