Methyl nitrobenzoate, also known as m-nitrobenzoic acid methyl ester, is a chemical compound with the formula C7H7NO3. It is a white, crystalline solid that is soluble in organic solvents, but not in water.
Methyl nitrobenzoate has a variety of uses. It is often used as an intermediate in the synthesis of pharmaceuticals and other chemicals. It has also been used as a flame retardant and a component of inks and dyes.
One of the most well-known uses of methyl nitrobenzoate is in the synthesis of aspirin. Aspirin is a common pain reliever and anti-inflammatory medication that is used to treat a wide range of conditions, including headache, muscle pain, and arthritis. Methyl nitrobenzoate is used as an intermediate in the synthesis of acetylsalicylic acid, which is the active ingredient in aspirin.
Methyl nitrobenzoate is also used in the synthesis of other pharmaceuticals, such as penicillin and cephalosporin antibiotics. It is also used in the production of fragrances, dyes, and resins.
Despite its useful properties, methyl nitrobenzoate can be toxic if ingested or inhaled in large amounts. It can cause skin irritation and allergic reactions in some individuals. As a result, it is important to handle and use methyl nitrobenzoate with caution, and to follow all appropriate safety guidelines when working with this chemical.
In conclusion, methyl nitrobenzoate is a chemical compound with a variety of uses, including in the synthesis of pharmaceuticals and other chemicals. It is important to handle and use it with caution due to its potential toxicity.
Analysis Of Meta
The precipitate was washed with 1 mL of water and 2 mL of methanol. All data proved that product is indeed methyl m-nitrobenzoate. Table 2: Data for Methyl Nitrobenzoate Percent Yield % Melting Point °C Appearance 18 79. . Figure 2: Figure 2 shows the mechanism for the formation of methyl m-nitrobenzoate from the reactants methyl benzoate and nitronium ion. How do you make nitro benzene? Why does the amount of the dinitration increase at high temperatures? I, 1932 , pp.
These peaks confirmed nitrobenzoate product and the melting point obtained proved it was in the meta position. This figure also shows the structure of the molecule with hydrogen peaks labeled accordingly. Methyl benzoate is used in flavourings. A benzene ring peak at 1615. In general, the resulting methyl m-nitrobenzoate has a purity of 98.

The methyl m-nitrobenzoate obtainable by the process of the invention is a useful starting material for the preparation of dyes and crop protection agents. Thus, the formation of byproduct increased immediately and reduced the amount of product aquired during the end of the experiment. The purification can be carried out as follows: Methyl benzoate is nitrated in accordance with one of the above-mentioned procedures, and the reaction mixture is diluted with water and filtered. ChEBI Name methyl benzoate Definition A benzoate ester obtained by condensation of benzoic acid and methanol. After the reaction, the mixture is poured onto ice, and the product is filtered off under suction. Mikrografie organelli komórkowych umożliwiają identyfikację nawet najmniejszych struktur, takich jak centriole, w systematycznym podejściu.
Komórki można zidentyfikować na podstawie ich błony komórkowej, ale mniejsze struktury wymagają obrazów TEM. How do you convert alcohol to ester? In the first step, the benzene ring acts as a nucleophile and attacks the nitrogen in the nitronium ion. This nitration is a type of electrophilic aromatic substitution. This can be done by reducing the nitro group into an amino group through the process of hydrogenation. Figure 5: Figure 5 shows the proton NMR spectrum for the product, methyl m- nitrobenzoate. Methyl acetate, also known as MeOAc, acetic acid methyl ester or methyl ethanoate, is a carboxylate ester with the formula CH3COOCH3. References: 1 Brown, W.
The suspension was heated at 75° l C. Nitration of Methyl Benzoate Lead Author: Bradley Wurth Reviewer: Elijah Marsh Editor: Hannah Strickland Chemistry 238 Section G Experiment 11 Introduction: Nitration of a benzene ring involves the addition of a nitro group. The methyl m-nitrobenzoate is then isolated in a conventional manner, for example by filtering, washing the residue with water, filtering once again and drying. Methyl propanoate can be prepared by esterification of propionic acid with methanol. The product was also determined to be meta by analyzing the melting point as well as the proton NMR spectrum. Using the equation shown in the data section, the total recovery weight came out to be 0.
Methyl Acetate, unlike Acetone, has a low odor which is suitable for furniture and automotive applications. Then, the white powder product was transferred to a pre-weighed flask and weighed on a scale. In this reaction, the nitronium ion can be added to three different locations on the benzene ring: meta, ortho, and para. The group added concentrated sulfuric and nitric acid too slowly in the beginning of the 15min period and a fast addition in the end of the 15min period. . Water and an amount, according to the invention, of an emulsifier are then added to the residue, which is not dried beforehand; the total amount of water is brought to the above amount. May be slightly toxic by ingestion.
An infrared spectrum of the product was obtained and confirmed it is methyl m-nitrobenzoate. The product was confirmed to be fairly pure by obtaining the melting point. Finally, proton NMR analysis was done on the final product, shown in figure 5. As a rule, from 2 to 10, preferably from 2 to 3, moles, of nitric acid are used per mole of ester.

. This experiment was helpful to understand how electron-withdrawing groups on a benzene ring direct to the meta position and how to create an electrophile in lab. What does benzoate smell like? At the end of stage b , the major part of the o-isomer forms an emulsion with the emulsifier and remains in the filtrate after the methyl m-nitrobenzoate has been isolated. Methyl benzoate is found in allspice. Product collected by vacuum filtration and recrystallized from 96% ethanol.
A process as claimed in claim 1, wherein the treatment is carried out using a mixture which contains from 70 to 94% by weight of the m-ester, from 0. Therefore, the substitution of ortho or para, appear be substituted at a less favorable position compare to the meta Dehydration Lab Report This type of solution is called minimum boiling azeotrope emedicalprep. So to prevent the alkene formed in the dehydration reaction forming back the alcohol, the alkene can be removed by distillation, because it has much lower boiling point than the… Grignard Reaction Lab Report The theoretical yield of 2-methyl-2-pentanol was calculated below: 0. Get your paper price 124 experts online After crystal product of m-methylbenzoate forms and purifies through recrystallization, its MP and IR will be taken to test purity and validate predicted position of the nitro group. The o-isomer can be isolated from the filtrate by steam distillation. These errors may have been due to problems with the gas… Wittig Reaction Lab Report IR was also obtained for the final product. This causes the NO2, the deactivating group, to be in the meta position instead of the ortho or para positions.
These impurities could have been unreacted reagents, water, or methanol. The reaction is carried out in general at between 0° and +40° C. Ingestion: May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. Contact may slightly irritate skin, eyes and mucous membranes. Next, the melting point was taken on the final product. Indicate the product formed on nitration of each of the following compounds: benzene, toluene, chlorobenzene, and benzoic acid. Nitric acid, sulfuric acid, and methyl benzoate will be mixed and added to an ice bath.
