Procedure and question

I want  an   equation for the reaction of 1-Butanol and 2-methyl-2-propanol   (t-butyl alcohol)  


Procedures :

Please notice that we used using ammonium salt instead of using HBr and HCl.

1.         

30 ml of sulphuric acid

40g of ice in a beaker

was poured into a 250 ml round bottom three-neck flask.

11.50 ammonium chloride was added

19.5 g of ammonium bromide

 

2.         

Reflux it

12.5 g of (1-butanol or 2-methyl-2-propanol) was added slowly

After 1 hour, 1-butanol result

After 0.5 hours, t-butyl alcohol result

Remove it when attaches to the boiling point

 

3.        Washed with 10 ml portions of concentrated sulphuric acid, one 75   ml portion of water, and one 75  ml portion of 3% aqueous NaHCO3.

 

4.        Use   50 ml Erlenmeyer flask to collect the organic layer

 

5.        Add few grams of anhydrous calcium chloride to the mixture to dry if from the excess water.

    5.0 ml of 2-methylcyclohexanol was placed in a 50 ml round bottom flask. Phosphoric acid (85%, 5 ml) was added cautiously, and the mixture swirled. Boiling stones were added to prevent bumping during heating. The mixture was heated to reflux temperature and refluxed for 15 minutes. The products were collected between 85-90 ˚C, in a small round bottom flask, cooled in ice water. Isolation Procedure The distillate was washed with 2 x 5 ml saturated sodium chloride solution in a...

    Introduction A common method for synthesizing alkenes is by dehydrating (removing the elements of water) an alcohol. The dehydration is accomplished by heating the alcohol with either phosphoric or sulfuric acid. In this experiment, the dehydration reaction is illustrated by the conversion of 2-methylcyclohexanol to a mixture of alkenes (remember the Saytzeff rule). Information Each step of this E1 elimination reaction is reversible and thus, the reaction may be driven to completion by removing one or more of the products,...

The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...
