The product of interests was able to eventually be separated due to extraction and washing using a separatory funnel and later short path distillation. The addition of water and diethyl ether allowed for the extraction of 1-ethoxybutane into the organic ether layer, and the sodium and bromide ions into the aqueous water layer. This was evident by the disappearance of the precipitate, because sodium bromide dissociated in water into its cation and anion components. In other words, the addition of water quenched the reaction and allowed for no other reaction to take place. 1-ethoxybutane remained in the ether layer because it was mostly nonpolar. The organic layer was on the top, and the aqueous layer was on the bottom due to the heavier weight supplied by the bromide ion of sodium bromide. Ultimately, the aqueous layer was washed away and the ether layer containing the desired product was left. The brine solution was added and acted as a pre-drying agent, where it extracted the water out of the organic layer. In molecular terms, the water is attracted to the ionic brine solution and thus drawn out into the aqueous layer. The addition of anhydrous sulfate dried the solution more and gravity filtration was performed to obtain the final products of 1-ethoxybutane and ether. Considerably, it is also important to note the purpose of the successive extractions of the aqueous layer twice with 10-15 mL of ether. This was due to satisfy the partition coefficient.
