Nitration of Methyl Benzoate BACKGROUND INFORMATION: Methyl benzoate is an aromatic compound structurally related to benzene. After each drop is added, or while adding each drop, swirl the mixture in the flask to insure even and uniform mixing. Since the product is a methyl ester, the methyl comes before the benzoate. Methyl ester of benzenesulphonic acid. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. <> Therefore, benzene becomes benzoate. Then, the other part of the ester (may be considered the ether portion) is put in front of the benzoate. Question: Nitration Of Methyl Benzoate The Purpose Of This Experiment Is To Enable The Stu- Dent To Learn About Electrophilic Aromatic Substitu- Tion Reactions And How Substituents On A Benzene Ring Affect The Orientation Of The Incoming Electro- Phile In Such Reactions. 1 0 obj Molecular Weight: 137.14. Ethylbenzene is produced in on a large scale by combining benzene and ethylene in an acid-catalyzed chemical reaction: C 6 H 6 + C 2 H 4 → C 6 H 5 CH 2 CH 3. Methyl groups tend to "push" electrons towards the ring - increasing the density, and so making the ring more attractive to attacking reagents. BRN 0908448. Alkylation means substituting an alkyl group into something - in this case into a benzene ring. Methyl benzoate 1. 2. Background Because aromaticity is a stabilizing influence, benzene rings do not undergo electrophilic additions as typical alkenes or non-aromatic conjugated p systems do. One common electrophile used in these reactions is NO 2 +, also known as the nitronium ion. Nitration of methyl benzoate – student sheet In this experiment you are going to synthesise a sample of methyl 3-nitrobenzoate by the nitration of methyl benzoate. In this experiment the purpose was to nitrate methyl benzoate to form methyl 3-nitrobenzoate.Methyl benzoate was treated with concentrated Nitric and Sulfuric . The reactivity of a benzene ring is governed by the electron density around the ring. Performance & security by Cloudflare, Please complete the security check to access. Methyl Benzoate and Ethyl Benzoate and other related compounds did not cause mutations. The reaction is regioselective and produces predominantly methyl 3-nitrobenzoate. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. General Mechanism For Nitration Of Benzene When adding the mixture of acids to the ester, it is important to keep the temperature of the reaction below 15 °C. It is a colorless liquid that is poorly soluble in water, but miscible with organic solvents. Draw out the skeletal formula for methyl benzoate. Methyl benzoate has a pleasant smell, strongly reminiscent of the fruit of the feijoa tree, and it is used in perfumery. Please enable Cookies and reload the page. 80-18-2.
