Unformatted text preview: most likely be attributed to water weight that remained after filtration and did not air out properly. The real returns are most likely significantly lower than represented. For melting points the extracted Benzoic acid melted at 92 o C, which is lower than its cataloged melting point of 122 o C. 4-tertButylphenol had a melting point of 65 o C while, 1-dimethoxybenzene had a melting point of 48 o C. The error in benzoic acids melting point range is most likely due to the substance being heated to quickly and not by one degree per minute. Please see attached sheet with calculated percent yields...
