Acetanilide is a white organic solid compound used primarily in organic synthesis. N-phenylacetamide, acetanilide and acetanil are other names of this compound. It was used in the past to treat fever and headache and was known as Antifebrin by its brand name. Table of Contents Aim Theory Materials Required Apparatus Setup Procedure Crystallization This chemical has chemical compound having a melting point in a range of 87-89oC. found application in the intermediation in dyes and dye p-Aminoacetanilide is used in the formation of assembly of Au intermediate synthesis and camphor synthesis. Besides, this is also nanoparticles of different sizes. still today fully compliant with all the green chemistry principles and consistent with the key aspects of sustainable development. Herein, we report on a sustainable mechanochemical procedure allowing the design of new amide frameworks via an eco-efficient "cut-and-paste" process of C−C and C−N bonds on the oxime backbone. We combined 44 Patrick Coppock et al.: Enhancing Research Skills and Attitudes in Undergraduate Organic Chemistry with a Course-Embedded Undergraduate Research Experience (CURE) via Green Organic Synthesis reaction being run). For the mole table: Use a 5:1 ratio of chlorosulfonic acid:acetanilide. Safety Notes: 1. Chlorosulfonic acid is extremely hazardous - wear lab Procedure. Wash all the apparatus with distilled water carefully before starting the experiment. Add a 20 ml aniline and 40 ml mixture of acetic anhydride and glacial acetic acid in a round bottom flask of 100 ml. Keep stirring the reaction mixture. Now add zinc dust to the flask. Fix a water reflux condenser to the round bottom flask Principle: • Acetanilide is an odorless solid chemical of leaf or flake-like appearance. Acetanilide was the first aniline derivative found to possess analgesic as well as antipyretic properties. • Acetanilide is prepared by acetylation of aniline with acetic anhydride and in the presence of sodium acetate and hydrochloric acid. (i) Dissolve 2 g of acetanilide in 2 mL of glacial acetic acid taken in a 100 mL beaker . (ii) Add 4 mL of conc. H 2 SO 4 gradually with stirring to the above mixture. The mixture becomes hot and clear solution is obtained. Cool the reaction mixture in an ice bath maintained at 0-5°C. (iii) Add a cold mixture of 1.0 mL conc. HNO 3 and 1.0 mL conc. H 2 SO 4 anescar1 Experimental Subject: Amide synthesis: Acetanilide Abstract: The objective of this lab experiment is to synthesize acetanilide in a reaction between aniline and acetic anhydride. Aniline is a basic primary amine, this reaction is prepared by involving the attack of a primary amine on the acetyl group of acetic anhydride. An anhydride of acetic acid acts as a source of acyl group in Take 1-2 mL LE and add lead acetate containing acetic acid. The formation of a black precipitate (PbS; lead sulphide) indicates the presence of sulfur. Purple-violet colour Black precipitate 3 Nitrogen and Sulphur present together Take 1-2 mL LE and add 2-3 crystals of ferr
