Unformatted text preview: Name: Lab Day: Isolation of Limonene From Orange Peels (6.2M) Results Show calculations for the following, where appropriate, in your notebook and indicate the page number where it can be found. _______ Mass of orange peels used: Mass of limonene isolated: % Recovery of limonene from peels: Temperature (range?) during distillation: Concentration of limonene in polarimetry solution (with units): Observed rotation, α : Specific rotation, [ α ]: % Enantiomeric excess of limonene: % R : Describe the isolated limonene. General Questions 1. Limonene and water co-distill at atmospheric pressure (assume 760 mmHg) at a temperature of 97.4°C. a- Look up the vapor pressure of water at this temperature and use this information to calculate the following: b- the vapor pressure of limonene at this temperature, c- the mole fraction of limonene in the limonene/water mixture that co-distills, and d-the corresponding mass percent of limonene. Report the values for a, b, c and d below and put the calculations in mass percent of limonene....
