calculate the temperature of an isothermal flash drum required to vaporize 40% of a liquid mixture of 60mol% isopropanol and 40mol% n-butanol. The flash drum operates at 0.5 atm absolute pressure. The feed enters at a rate of 100kmol/hr and at 1 atm and 50 Celsius. Give the compositions of the liquid and vapor phases formed.
In trans-1,2-dibenzoylethylene, even though the conjugated C=O group frequency coincides directly with the expected C=C stretching fequency, we would not have expected to observe the late stretching mode in the infrared spectum. Why?
