EWhat are the advantages of using steam distillation in the recovery of organic liquid from a micture?
Step by step
Solved in 2 steps
- What are the differences between a simple distillation and steam distillation?How to increase thw yield of steam distillation?3. A pure white crystalline compound was found to melt at 131.5-132.0°C when taken on a melting point apparatus, and on further heating, the liquid was found to start bubbling at ca. 155-160 °C. The capillary containing the melted compound was set aside to cool, and resolidify. When the sample was retried using that same capillary, the sample melted at 120.6-154.5°C, along with some bubbling. What is the cause of the bubbles? Why is the melting point so wide the second time? Explain by stating what you have learned in this laboratory about melting points.
- Why is fractional distillation more efficient than simple distillation when purifying liquid mixtures?What is the function of a desiccant in a set-up of volatilization gravimetry? To remove nitrogen from the sample To remove sulfuric acid from the sample To remove water vapor from the sample To remove carbon dioxide from the sampleExplain the reasons for the importance of crystallization step involved in the manufacturing of bulk drugs?
- Explain the principle behind vacuum distillation.When you are extracting an aqueous solution with an organic solvent, you are uncertain of which layer in the separatory funnel is aqueous, how would you quickly sort out the issue.5 g of cobalt carbonate and 13 mL of concentrated hydrochloric acid were used. In another glass, prepare a solution with 8.4 mL of anhydrous ethylenediamine and 2.8 mL of concentrated hydrochloric acid. They are mixed and added and 6.5 mL of peroxide were added to it.30% hydrogen, thenconcentrated hydrochloric acid is added, followed by60 mL of ethanol. 5.1234 g were obtained orange solid [Co (en) 3] Cl3 What is the percentage yield of the reaction. The reactions are shown in the images.
- Compare simple and fractional distillation for the separation of HEXANE and TOLUENEA student performs a crystallization on an impure sample of biphenyl. The sample weighs 0.5 g and contains about 5% impurity. Based on his knowledge of solubility, the student decides to use benzene as the solvent. After crystallization, the crystals are dried and the nal weight is found to be 0.02 g. Assume that all steps in the crystallization are performed correctly, there are no spills, and the student lost very little solid on any glassware or in any of the transfers. Why is the recovery so low?What are the important solubility characteristics for a solvent for crystallization of an organic solid that is contaminated with a small amount of impurity?
