IR Conclusion and Data Analysis In experiment four, a liquid-liquid base extraction was used, a mixture of 1:1 Acetanilide:Benzoic Acid was separated and then was purified using recrystallization methods. The layers, were also separated; the HCl was then used to be able to neutralize the Benzoate and bring it, back to benzoic acid. In the process was later removed the excess HCl which was used to, protonate Benzoate while the vacuum filtration was functioning and removed Na2SO4 which. All rights reserved. It is also known as N-phenylacetamide, acetanil, or acetanilid, and was formerly known by the trade name Antifebrin Preparation and properties. It derives from an acetic acid.

Molecular Formula: C8H9NO: Exact Mass: 135.068414 g/mol: Transmission Infrared (IR) Spectrum. SpectraBase Spectrum ID=BZrKkLzXdnU The crystals were weighted in order to calculate the percent yields and the melting, points were also tested.
The actual yields obtained in the experiment were 0.2100gr for, benzoic acid and 0.1023 for acetanilide (Table 1). The theoretical yield was 0.5 gr for each, of the compounds extracted. In fact, for example, when observing Figure 4 the peaks in the benzoic acid were, correlated with the ones found in the benzoic acid’s molecule.

Anal. In Figure 6, the peaks correlate. (Rus. Stable. NaOH was the solvent used to perform the extraction of the benzoic acid from acetanilide by, deprotonating the carboxylic acid in benzoic acid and converting it into the conjugate base called, Benzoate. 1H Nuclear Magnetic Resonance (NMR) Spectrum of Acetanilide with properties.

Comparing this values with the literature values (121-123 °C, for benzoic acid and 111-115 °C for acetanilide) showed that the extracted compounds were very, The IR and NMR spectras previously observed confirmed the identity of acetanilide and, benzoic acid. The process just described also created two immiscible layers which were the organic, layer containing DCM with Acetanilide and the aqueous layer containing Benzoate.
