A liquid unknown is insoluble in water and soluble in cyclohexane and alcohol with a boiling point of 145 C at 658 mm Hg. What is the substance?

To find the substance, you can use a Nomograph Table. Take the observed boiling point and the pressure to find the change in temperature correction. It was found that the actual boiling point was 3.5 degrees off what was stated, so the boiling temperature is 60.5 degrees Celsius. The compound has a boiling point of approximately 60.5 degrees (1) in water and (s) in cyclohexane and alcohol. Chloroform is extremely close to this, with its normal boiling point being 61 degrees Celsius and it matches everything else.

How could you seperate benzophenone from a-naphthol?
The melting point for lauric acid is about 45 degrees while it is 121 degrees for naphthol. So, in a mixture repeated cycles of slow warming and cooling should separate out lauric acid from naphthol. You can improve the efficiency by adding a dash of slightly acidic 70% isopropyl alcohol. This will deprotonate the lauric acid while maintaining the proton on naphthol during this process to enhance separation and purification of the two compounds. You could also flat-out distill the two products by maintaining the temperature of the solution at the boiling point of lauric acid to separate it from naphthol.
Does Cyclohexene has a lower boiling point than either cyclohexanol?
Yes, cyclohexene has lower boiling point than cyclohexanol (and cyclohexane as well)
What is steam distillation and why is it a preferred technique to purify high boiling liquids that are water insoluble?
steam distillation is an effective way to separate slightly volatile water insolube substance from nonvolatile material

What is the boiling point of cyclohexane experiment?
This depends on the pressure.
What is the effect on the boiling point of water when you add insoluble substances?
it could be splash or bomb because you put an insoluble substance eh so it has the tendency it will bomb because also of the gravity:)
What is the effect of an insoluble solid such as glass on the boiling temperature of a liquid?
If the solid is insoluble, it will have little or no effect on the boiling point. If it is soluble, it will raise the boiling point.
What is the physical state of cyclohexane?
At room temperature cyclohexane is a liquid. According to the Wikipedia article on cyclohexane, it's melting point is 6.47 degrees C and it's boiling point is 80.74 degrees C.
Does Cyclohexene has a lower boiling point than either cyclohexanol?
Yes, cyclohexene has lower boiling point than cyclohexanol (and cyclohexane as well)
How does the addition of stone affect the boiling pont of water?
If the stone is insoluble the boiling point is unchanged.
Boiling point of cyclohexane at 600mm Hg?
The boiloing point of toluene at atmospheric pressure of 760 mm (torr) is 110.5 deg C. Reducing the pressure lowers the boiling point. The boiling point of toluene at 600 mm (torr) is 104.0 deg C.
What is the meaning of boiling and of boilingpoint?
Boiling is to heat an liquid to the point where it will turn from a liquid to a gas. Because the substance cannot be at temperature higher than its boiling point the temperature will remain that until all the liquid has been boiled away. That is why if I were to heat some alcohol and water the temperature would remain at about 60oC until all the alcohol had evaporated away. Then the temperature would go to 100oC and the water would boil. The boiling point of substance is the temperature at which the substance will turn from a liquid to a gas. This is about 100oC for water.
How pressure attract boiling point in cyclohexane?
It is impossible to 'attract' any boiling point (whatever that may mean):Boiling point is a physical property of a particular liquid compound depending on pressure.
What substance has a boiling point of 100 Celsius?
it is some type of alcohol did a distillation lab on it today
What is steam distillation and why is it a preferred technique to purify high boiling liquids that are water insoluble?
steam distillation is an effective way to separate slightly volatile water insolube substance from nonvolatile material
