It is very important to regulate the temperature of the heating mantle so that the distillation occurs at a rate of about 1 drop per 2 seconds. Why?What is different about steam distillation
- 6 Assuming that hexane and water obey the required solubility criteria, why could they still not be used as a solvent pair in a mixed solvent recrystallization? Explain.True or False. It is very important to regulate the temperature of the heating mantle so that the distillation occurs at a rate of about 1 drop per 2 seconds. Explain why?3.Why is it dangerous to perform distillation on a closed (airtight) system?
- Compare the simple distillation of pure hexane and binary mixture of hexane and toluene to that of a fractional distillation?4.It is tempting to maximize the amount of product isolated by continuing the fractional distillation until no solution remains in the distilling flask. Why is this not done?Give the equation for boiling point correction and explain the meaning of each variable. Why do we not need to correct boiling points when running distillation experiments at a simple school level?
- Although we will not use a Claisen adapter in our apparatus, what quality of vacuum distillation does it mitigate?Compound A is impure and has a melting point of 90°C - 98°C. After purification, A will most likely have a melting point of: *In most distillations, the total volume of liquid obtained (distillate + residue) is possible sources of loss in this procedure?
