considerably decrease. Furthermore, the sample itself was not very pure and was only obtained from one group, as opposed to combining the most pure sample from different groups. This could have caused some major issues during the procedure, since the starting substance itself was not available in optimum quantity and condition. Lastly, the transfers of solution could have leaked some of the solution, leading to an optical purity of 56.35% Conclusion The S -(-)-a-phenylethylamine enantiomer was separated from phenylethylamine mixture using tartaric acid as a resolving agent which produced two diastereomeric salts. These diastereomeric salts were then separated using vacuum filtration. Furthermore, the amine solution was tested for optical rotation in a polarimeter cell to determine the specific rotation, and thereafter, the optical purity. The observed rotation was -12.225 degrees, the specific rotation was -22.711 degrees, and the optical purity of the amine was 56.35%. The major enantiomer was s-(-)-a-phenylethylamine since the specific rotation was negative, indicating a left rotation.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
