Can someone just give me a reaction that I can do on carvone that once I react it with tartaric acid it gives two diastereomers? I’m so confused now
Combinations of solvents that do not form an azeotrope when mixed in any proportion are said to be zeotropic. Azeotropes are useful in separating zeotropic mixtures. An example is acetic acid and water, which do not form an azeotrope. Despite this, it is very difficult to separate pure acetic acid (boiling point: 118.1 °C) from a solution of acetic acid and water by distillation alone. As progressive distillations produce solutions with less and less water, each further distillation becomes less effective at removing the remaining water. Distilling the solution to dry acetic acid is therefore economically impractical. But ethyl acetate forms an azeotrope with water that boils at 70.4 °C. By adding ethyl acetate as an entrainer, it is possible to distill away the azeotrope and leave nearly pure acetic acid as the residue.
acetic acid 118.1C No azeotrope
... separating it from water is tricky, since they're both matching azeotropes and not even fractional distillation will work out.
...(Im not that interested in getting a very pure batch, 50% or more is good enough for me).
