Problem 4 Jasmone (molecular formula C₁H₁60) is a valuable specialty chemical that is obtained from the jasmine plant. A common method of manufacture is to extract the plant material in water, and then use benzene to concentrate the jasmone in a simple liquid-liquid extraction process. Jasmone (species A) is 170 times more soluble in benzene than in water, and so C₁ = 170 CA where is the concentration of jasmone in benzene, and ca is the concentration of jasmone in water. In a proposed extraction unit, the benzene phase is well mixed with the film mass- transfer coefficient k = 3.5 x 10-6 m/s. The aqueous phase is also well mixed with its film mass-transfer coefficient k = 2.5 x 10 m/s. Determine a. The overall liquid mass-transfer coefficient. K₁, based on the benzene phase b. The overall liquid transfer coefficient, K₁, based on the aqueous phase c. The percent resistance to mass-transfer encountered in the aqueous liquid film Note: For any parameter or variable values that you need refer to the tables and appendices of the course textbook.
