Solid C Synthesis
Extraction and analysis of two compounds from unknown solution C
ABSTRACT
Liquid C and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract, followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization, the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119.0C while the boiling point of liquid C was found to be 117C. The identity of solid C and liquid C was found to be benzoic acid and butyl acetate respectively.

Analysis of the C13-NMR for liquid C showed 5 distinctive peaks in the range of 0-80 ppm and one peak around 170 ppm indicating a carbon skeleton consisting of six carbons. The four peaks at 30.34ppm, 20.41ppm, 18.77ppm, and 13.25ppm are representative of primary and secondary alkyl carbons. Additionally one peak 63.82ppm strongly indicates an ether functional group and the remaining peak at 170.53ppm is representative of an ester carboxyl functional group. In terms of the analysis for the H1-NMR, several peaks were present that mimicked the types of functional groups present in the C13-NMR. Such includes peaks from 0.4-1.5ppm that are representative of primary and secondary alkyl functional groups, and peaks at 3.921ppm, 3.899ppm, and 3.876ppm which are strongly indicative of an ether functional group. After analysis of the IR spectrum, further confirmation of the functional groups found in the H-NMR and C-NMR were seen in the IR. Such peaks include multiple variable peaks ranging from 1200-1300cm-1 that show a Csp2-O oxygen bond that can be inferred for the ether functional group. Additional characteristic peaks include peaks ranging from 1680-1750cm-1 that represents a ketone functional group is present, and a broad sharp peak ranging from 3200-3559cm-1 which is indicative of concentrated alcohols and phenols. This is, however, not supported by the NMR spectra, and hence suggests the presence of impurities, especially in regards to the concentrated alcohol and phenol peak. The boiling point of butyl acetate is 126C according to literature. However, the boiling point observed during distillation was 117C, a lower measurement likely due to the presence of impurities as suggested by the IR
