Nitration

Abstract This experiment is about the synthesis of 3-nitrobenzaldehyde through nitration. The nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction, in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a suitable electrophilic reagent, and many other groups besides nitro may be introduced into the ring. Although the reaction produced a low

point.

Nitration of Methyl Benzoate Purpose: The purpose of this experiment was to synthesize methyl m-Nitrobenzoate from methyl benzoate, concentrated HNO3, and concentrated H2 SO4 by an electrophilic substitution reaction. The H2 SO4 and the HNO3 were initially combined to form nitronium ion which was then used as an electrophile in the reaction. Crystals that were collected after the formation of the methyl m-Nitrobenzoate were collected by vacuum filtration and the product was isolated and purified

Nitration of Naphthalene Wed 2/25/2015 Lab report # 1 Abstract: The purpose of this experiment was to nitrate naphthalene with nitronium ion, which is formed at low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product, and the melting point of the possible results were 59 °C for 1-nitronaphthalene, and 78°C for 2-nitronaphthalene. Introduction: Polynuclear aromatic hydrocarbons such as naphthalene can be nitrated

 Purpose:
The main objective of this experiment was to synthesize methyl nitrobenzoate from methyl benzoate, using the mixture of nitric and sulfuric acid by performing the process of electrophillic aromatic substitution. During this reaction, the combination of HNO3 and H2SO4 made a nitrating solution. The crystallization was done to accomplish pure product. The melting point and Thin Layer Chromatography (TLC) were performed to test the purity of the product. Using

In the nitration experiment, a 5 mL conical vial was obtained, and a rice stir bar along with 0.5 mL of concentrated nitric acid was added to it. Slowly 0.5 mL of concentrated sulfuric acid was added to the nitric acid. The conical vial was placed in the appropriate hole in the aluminum heating block and the heat was turned to 50 degrees Celsius. The conical vial was attached to the micro-jacket condenser. The water hose was not attached to it. Then 0.5 mL of bromobenzene was slowly added dropwise

Nitration of Methyl Benzoate Abstract: This procedure demonstrates the nitration of methyl benzoate to prepare methyl m-nitrobenzoate. Methyl benzoate was treated with concentrated Nitric and Sulfuric acid to yield methyl m-nitrobenzoate. The product was then isolated and recrystallized using methanol. This reaction is an example of an electrophilic aromatic substitution reaction, in which the nitro group replaces a proton of the aromatic ring. Following recrystallization, melting point and infrared

identity of the major product will be discovered. The method used to reach the purpose of the experiment is a TLC. The nitration of methyl benzoate with a mixture of sulfuric acid and nitric acid will be performed in the experiment. NO2 is the electrophile in the experiment, and it is an electron withdrawing group that makes the methyl benzoate less reactive. The NO2 group in this nitration can be added to three different positions —ortho, para, or meta. When the NO2 is added, it makes a methyl nitrobenzoate

The purpose of this experiment was to create a hypothesis concerning what product would produce in the mono-nitration of methyl benzoate. The hypothesis made stated that the product of the mono-nitration of methyl benzoate would be methyl-m-nitrobenzoate. A nitration reaction was executed and was used to describe by means of high performance liquid chromatography, (HPLC). My partner and I obtained concentrated H2SO4 and mixed it with methyl benzoate in a reaction tube in a flicking manner. A

NITRATION OF METHYL BENZOATE Bachelor of Science in Human Biology College of Science, De La Salle University - Dasmariñas ABSTRACT ___________________________________________________________________________________ Aromatic hydrocarbons are electron rich and are stable because it has a benzene ring. It undergoes Electrophilic aromatic substitution, and the nitration of methyl benzoate illustrates this type of reaction. The objective of this experiment is to synthesize methyl m-nitrobenzoate
