Bromination of Butanol Laboratory Conclusion: Drew Rasmussen November 19, 2011 After being assigned an unknown alcohol, the chemist was to perform a qualitative analysis to determine whether the alcohol was 1-butanol or 2-butanol. The start alcohol was then reacted with HBr in the presence of H 2 SO 4 (as a catalyst) to produce a final product which had a cost analysis done for efficiency measures. To ensure that the final product had been brominated, the Beilstein Flame test was performed to check for the presence of halogens. The Lucas Test was used on the starting alcohol to identify if the alcohol was secondary or primary. After the identity had been checked, a reaction apparatus was setup and the 2.5mL HBr, 0.5mL H 2 SO 4 , and 1.65mL of Alcohol A was refluxed for 1 hour. The reaction mixture was then transferred to a centrifuge tube for the extraction process which was done with 5 mL of water, 2 mL of cold concentrated H 2 SO 4 , 2 mL of water, and finally with 2 mL saturated sodium
