-Pentyl Chloride Synthesis

Because the boiling point of t-pentyl chloride is lower than that of t-pentanol, the vapor that forms over the crude product solution will contain a larger fraction of t-pentyl chloride as compared to the solution from which the vapor formed. As the vapor condenses in the fractionating column a new solution is formed.

Problem 1QPC from Chapter 23

(a) The aqueous sodium bicarbonate wash is mainly there to neutralize the trace amounts of HCl present in solution due to elimination byproduct or hydrolysis of alkyl halide (-pentyl chloride). The bicarbonate is a weak base that will react and neutralize the HCl. The equation is as follows:

OH HCl (conc.) Cl + H O

Aqueous sodium bicarbonate neutralizes any remaining, unreacted HCl. These washes should be done relatively quickly to prevent hydrolysis of the product back to alcohol.

OH HCl (conc.) Cl + H O

Synthesis of t-pentyl chloride Competition with elimination is not an issue and alkene side-products are not formed because the reaction occurs at room temperature. The isolation of the product from solvent and by-products is called the reaction work-up. The crude reaction mixture is washed with water to dilute and remove excess HCl.
