Base Extraction of Benzoic Acid from Acetanilide. 3 g of acetanilide and 0. 2 Aim The purpose of this experiment was to extract/isolate benzoic acid and acetanilide from their respective solvents through synthetic laboratory procedures. Prachi Patel CHEM 233 Xuan Duong 02-25-2021 Lab Report: 4 Base Extraction of Benzoic acid from Acetanilide; Recrystallization of products Introduction: The main objective of this lab is to separate 1:1 mixture of benzoic acid and acetanilide is with NaOH(aq). Three compounds were extracted: m-Nitroaniline (base), benzoic acid (acid), and naphthalene Experimental Procedures The first part of the experiment consisted of the extraction procedure. 3 Steeping a teabag in hot water or washing a load of laundry are solid-liquid extractions. 97% “Experiment 5 Preparation of Benzoic Acid using a Grignard Reagent” Table of Reagents Compound Tanvi Kulkarni 10/06/ Lab 4: Base extraction of Benzoic Acid from Acetanilide; Recrystallization of Products.

Abstract: By using several steps of extraction, the purpose of this experiment is to separate the The structures of benzoic acid and acetanilide are presented below (Figure 1): Figure 1:Structures of Benzoic Acid (left) ad Acetanilide (right) To separate the benzoic acid from the acetanilide, base extraction was employed. This shows the saying “like dissolves like”, comes into play.
