Elizabeth Doane Discussion: The neutral, or the unknown RH in the “Wellactin” was closest to bi-phenol when comparing its melting point range and the most effective solvent. The acid, the unknown RCOOH was closest to 4-Toulic Acid. The bi-phenol was less pure than the 4-Toulic Acid. This was determined from the bi-phenol’s longer range of melting points. At first the purity of the bi-phenol was relatively low. Especially when noting the melting point first calculated. While the melting point of pure bi-phenol is 68.98 degrees C, the melting point range of my less pure sample was 39.6 – 45.5 degrees C.

Unformatted text preview: Overall, I was able to recover 57.05 %. I was also able to purify my RH. I was able to raise the melting point a significant amount – to a range of 65.2 – 68.3 degrees C. This melting point corresponds more to bi-phenol. I believe this was an efficient procedure and experiment. I was able to not only separate the three components of the compound, but I was also able to identify them, even the RH in a very impure form. I was also able to purify the RH to make it much more identifiable and more pure....
