Which reaction can be used to synthesize cyclohexene from cyclohexanol?
In this experiment an alkene (cyclohexene) will be prepared by dehydration of an alcohol (cyclohexanol) using an acid catalyst such as phosphoric acid. This is one of the most common methods of preparing alkenes. The crude product is contaminated with water, unreacted alcohol, phosphoric acid and some side products.
How do you synthesize cyclohexene from cyclohexane?
The most common method of making cyclohexene is by taking cyclohexanol (cyclohexane with an −OH group attached to it) and treating it with an acid of some sort. When cyclohexanol is reacted with an acid it undergoes a reaction called a dehydration reaction, which means it loses a water molecule.
How do you synthesis cyclohexanone?
The synthesis of cyclohexanone is simple. First, sodium hypochlorite and acetic acid are reacted to yield hypochlorous acid. Second, hypochlorous acid is added to cyclohexanol to synthesize cyclohexanone via Chapman-Stevens oxidation reaction.
Why distillation technique is used during cyclohexene synthesis?
Distillation from boiling water ensures that only cyclohexene will be distilled (b.p. 82 °C). Other possible contaminants (water, cyclohexanol, sulfuric acid) will not boil at the temperature of boiling water.
How do you calculate theoretical yield of cyclohexene?
Convert this number of moles of cyclohexene to grams of cyclohexene by multiplying by the MW of cyclohexene (82.1 g/mol). In other words, 2.05 g of cyclohexanol should produce 1.68 g of cyclohexene. This is the best-case yield also known as the theoretical yield.
What is the molecular formula of cyclohexene?
C6H10Cyclohexene / Formula
Cyclohexene is a hydrocarbon with the formula C6H10. This cycloalkene is a colorless liquid with a sharp smell.
How do you make cyclohexane?
A method for preparing a cyclohexane comprises the following steps: a benzene and a hydrogenation catalyst are driven to enter a distillation tower from the tower top and the hydrogen goes into the distillation tower from the tower bottom; the tower bottom is heated by the steam and a reaction in which the benzene …
How do you find the theoretical yield of cyclohexanone?
As 0.15 mol of cyclohexanol is going to undergo reaction, 0.15 mol of cyclohexanone (Mw 98 g/mol) should be produced. Therefore, the theoretical yield is: 0.15 mol x 98 g/mol = 14.7 g.
