Nitration of Acetanilide

Introduction

When organic compounds are nitrated it changes the composition and reaction of the compounds.[4] We could benefit from these changes, nitration of acetanilide produces a product called p- Nirtoanoline. P-Nitroaniline is commonly used as an intermediate in the synthesis of dyes, antioxidants, pharmaceuticals and gasoline. P-Nitroaniline is also used in gum inhibitors, poultry medicines and as a corrosion inhibitor. [2] Nitration is a type of chemical reaction which a nitro group is added to or substituted in a molecule. It can be carried out by a mixture of concentrated nitric acid and sulfuric acid. Mixture is useful to obtain the active nitronium ion. Electrophilic aromatic substitution is a method used when a functional group is needed to be substituted on to an aromatic compound. In the nitration, nitronium ion acts as the electrophile that involves the attack of the electron-rich Benzene ring. [3] In this experiment nitration is carried out using acetanilide and allows this chemical to be used in a way that could be beneficial for our use.

Procedure

Gathering products

Weighed out 0.202g of acetanilide powder and add 500µl of sulfuric acid to the viol, stir and loosen up clumps. Obtained another clean conical viol, added 110µl of nitric and sulfuric acid to the clean conical viol, then we put the viol with the acid mixture on ice.

Nitration

We added 55µl of the acid mixture (nitric and sulfuric acid) to the viol with the acetanilide and sulfuric acid. We did this for a total of three times until all the acid mixture was added to the acetanilide viol. We put the acetanilide mixture viol in a 10 mL beaker of ice water for 10 minutes. Added 2 mL of ice and water to the acetanilide viol.

Filtration

We filtered and dried the product using the Hirsch funnel filtration, while rinsing the viol with 1 mL of DI water to get the rest of the acetanilide mixture out of the viol. Allow the

    Although the acetanilide and aspirin are both quite insoluble in water at room temperature, the sodium salt of aspirin is very soluble in water but insoluble in dichloromethane. Because aspirin is a reasonably strong acid, it can be converted to the salt, sodium acetylsalicylate, by reaction with the basic sodium hydroxide. While the two layers are thoroughly mixed, the aspirin will react with the sodium hydroxide in the bottom layer, which then migrates to the aqueous layer and can be easily separated in a separatory funnel. Adding some dilute hydrochloric acid to the aqueous solution restores free aspirin as an insoluble white solid; evaporating the solvent from the bottom layer leaves the acetanilide behind.…

    The solution then gets foggy/cloudy and white snowlike precipitate is floating within the solution. Heat is added along with a stir bar. The stir bar starts stirring at minute 7. It begins to dissolve the white powder as it spins. At minute 26 the solution becomes clear with barely any flakes left. Sulfuric acid is then added and white flakes are formed. More acid is added until the pH paper turns red. The round bottom is filled with white precipitate. The precipitate is put onto a hirsh funnel that uses vacuum filtration to isolate the precipitate. The product is then added to a beaker with D.I water and heated. It’s put through the hirsh funnel . 3.68 grams of salicylic acid is recovered. The melting point is tested to compare to a perfect sample. The melting point is 146C0. The product is dried and added to a beaker with D.I. water and 10mL of acetic anhydride and 20 drops of concentrated sulfuric acid. This product is chilled to produce crystals. Its then filtered using a hirsh filter using vacuum filtration. Recrystallized and filtered one last time. The product is now acetylsalicylic acid…

    Procedure: To a 125 mL Erlenmeyer flask containing a mixture of 95% ethanol (6 mL) and acetic acid (5 mL), dissolve acetanilide (7.4 mmol) and sodium bromide (1.8 g). Place the reaction flask in an ice bath (at least 5oC) for 5 minutes (keep this reaction in the hood). Add sodium hypochlorite (8.3 mmol) by addition of household bleach; leave the reaction flask in the ice bath 5 min. After removing the flask from the ice bath and placing a watch glass over the opening, allow the reaction mixture to come to room temperature over 15 minutes. Place the reaction flask into the ice bath and quench the unreacted bromine by addition of both 5 mL of sodium thiosulfate solution (1 g/5 mL) and 5 mL sodium hydroxide solution(1 g/5 mL ); collect the product by suction filtration. Recrystalllize the brominated product from a minimum amount of solvent. You will need to select a solvent from water, 50% ethanol or 95% ethanol. To identify the best solvent, use what you have learned in Organic I Chemistry Lab, hint: think about what properties makes a good recrystallization solvent. Test your recrystallization solvent in test tubes using the tip of a spatula of your compound. Remember to use a water bath to heat organic solvents. NEVER heat organic solvents directly on a hot plate-always use a hot water bath! Dry the product and obtain melting point range (one fast and one slow) and an IR spectrum. Be sure to record observations in your laboratory notebook.…

    First, nitronium ion is made by the reaction between nitric acid and sulfuric acid, with sulfuric acid acting as a protonated reagent. The nitronium ion is a strong electrophile that can react with benzene ring to form the arenium ion intermediate, despite the fact that it can temporarily lose its stability provided by the resonances. After that, it regains its stability by deprotonating the intermediate and yields the final product, in this case is methyl-m-nitrobenzoate. This experiment will be carried out under controlled temperature of 15oC or lower, since higher temperature will result in the second nitro group addition. In this experiment, student will observe the mechanism of electrophilic aromatic substitution reaction through the nitration of methyl…

    Through the top of the condenser, 14 mL of concentrated sulfuric acid was added drop wise over a period of ten minutes. The addition of the acid created a change in color of the solution to a rustic orange color. The mixture was refluxed for 30 minutes and the solution changed to a faded yellow-orange color. Once reflux was complete, a simple distillation was set up, with the 25 mL collection graduated cylinder placed in an ice bath. The mixture was distilled and combined with the hood partners’ distilled mixture. The distillate was placed in a separatory funnel with 10 mL of distilled water. Once separated, the distillate was added to the funnel again with 9 M sulfuric acid. The organic layer was still in the funnel after separation, as distilled water was added to the solution and then 10 mL of a saturated solution of sodium bicarbonate. The organic solution was dried with anhydrous sodium sulfate for a week. The liquid product was transferred to a 25 mL round bottom flask equipped with a stir bar and a simple distillation was set up. The solution was distilled and the density of the bromide was calculated at 1.222 grams/mL with a boiling range of 87-92◦C. The theoretical yield was calculated at 12.847 grams and the percent yield was 72.3 percent. Next was the characterization and assessment of the purity of the…

    Writing ink can be made from many natural sources, such as the fruit juice of the alugbati plant. Alugbati, known in the U.S. as Malabar spinach, is commonly grown for its soft, spinach-like leaves and shoots. Alugbati is of African and East Asian origin. The juice of the fruits was reportedly used in ancient China as ink for official seals. Today, the fruits of the red-stemmed alugbati variety can be used to make ink. As of May 2010, the government of the Philippines is researching commercial production of ink extracted from the alugbati fruits.…
