Calculate your percent recovery for both camphor and ß-carotene. Using sublimation, a student attempted to separate camphor (mp 175-177 °C) from borneol (mp 206-208 °C) by sublimation at 120 °C at atmospheric pressure. When no more crystals appeared to sublime, the student stopped and scraped the sublimed crystals from the centrifuge tube. The melting point of the solid was 150-160 °C. Was the student successful in the separation? Briefly explain. What do your measured melting point ranges indicate about the purity of your camphor and ß-carotene? (optional) (a) Calculate the molar absorptivity & for the maximum absorption of your ß-carotene sample. Compare your calculated & with the literature value. (b) Compare your spectrum with that of a standard sample of ß-carotene, found in Figure 4 later in this experiment. Calculate your percent recovery for both camphor and ß-carotene.
