Diethyl Ether Boiling Point Vs Pressure

Although we usually cite the normal boiling point of a liquid the actual boiling point depends on the pressure.

Diethyl ether boiling point vs pressure. Recall that diethyl ether has weak dispersion forces which meant that the liquid has a high vapor pressure. At a pressure greater than 1 atm water. Boiling point of ethyl ether and its relation to pressure by miec1 yslaw wojciechowski 1 abstract ethyl ether of a high degree of purity was prepared and its boiling point was found to be 34 481 0 003 c. The normal boiling points of the other liquids in figure pageindex 4 are represented by the points at which the vapor pressure curves cross the line corresponding to a pressure of 1 atm.

Ether peroxides have a higher boiling point than ether and are contact explosives when dry. The weak forces also mean that it does not require a large an input of energy to make diethyl ether boil and so it has a relatively low normal boiling point of 34 6 c. Chemsrc provides diethyl ether cas 60 29 7 msds density melting point boiling point structure formula molecular weight etc. Boiling point and or vapor pressure estimates of various liquids can be derived using the clausius clapeyron equation.

Ratio of ethyl ether degrees per mm at 760 mm of hg is 0 0372. The volatility of diethyl ether is evident from a vapor pressure more than 20 times that of water at these temperatures. This difference can be demonstrated by means of a buret clamped upside down in a reservoir of water several ml of air trapped in the buret above a column of water and a funnel attached to the buret nozzle. Use the calculators below to find the boiling point and or vapor pressure of a liquid.
