Why after a nitration reaction?
For example nitrobenzene is obtained by nitration of benzene.
Discuss the SN reaction with example?
The SN reaction is a substitution reaction. An example of the SN reaction is Br. H3CH2C.
How to convert aniline to picric acid?
React aniline with HCl/NaNO2 (diazotisation) followed by reaction with KOH to give phenol. Nitration of phenol with fuming nitric acid gives picric acid (or trinitrophenol).
Is photosynthesis an example of an endothermic reaction yes or no?
No, photosynthesis is not an example of an endothermic reaction. It is an example of an exothermic reaction because it releases energy in the form of glucose and oxygen.
What is the preparation process of 5-nitrosalicylic acid?
The 5-nitrosalicylic acid is synthesized by nitration(generates the intermediate 2-Chloro-5-nitrobenzoic acid, and hydrolysis(generates the target product) of o-chlorobenzoic acid. The influences of the nitration of temperature, proportion of mixed acid and of the hydrolysis of temperature, reaction time were investigated. The yield of nitration was 95.7% with a mixed acid of nitric acid : sulfuric acid = 9 : 1, in the course of 0 ℃ and 8h, and the yield of hydrolysis was 98.3% in the course of 140 ℃ and 16 h. The final product (HPLC≥99.8%) was obtained after recrystallizing by the proper ethanol solution.
Why after a nitration reaction?
For example nitrobenzene is obtained by nitration of benzene.
Why nitration reaction is not used for synthesis of p-nitroaniline?
due to we do this reaction in acidic condition here the formation of anilinium ion takesplace which is deactivating group then if we add nitration mixture substitution takes place at meta position means we don't get 4-nitroaniline
Why nitration of nitrobenzene is difficult than nitration of benzene?
because nitro group is ring deactivating group, nitration of nitro benzene is more difficult than benzene.
What has the author KENNETH K CARROLL written?
KENNETH K. CARROLL has written: 'MECHANISM STUDY OF THE NITRATION OF DI-N-OCTYLAMINE BY THE CATALYZED BAMBERGER REACTION'
How do you do nitration of salicylicacid?
Well a standard nitration with mixed acids at elevated temperatures. One could just follow the nitration of its brother, acetylsalicylicacid (ASA) as in the same way TriNitroPhenol (TNP) is made.
Explain why nitration are usually carried out at comparatively low temperatures?
In most of the nitration processes heat is require but relatively (as compare to sulphonation) low temperature is due to volatile nature of nitrating agent which is usually nitric acid, at higher temperature nitric acid may decompose or may escape from the reaction vessel.
Why direct nitration is used in picric acid?
in picric acid we cannot used direct nitration because of the phenol is very sensitive in oxidation of nitrate, to overcome this problem, we used a sulfuric acid added to phenol before the nitric acid. the reaction between NO2 and SO2 are reversible so the sulphate exchange with nitrate becoming tri nitrophenol
Is exothermic reaction an example of photosynthesis?
An exothermic reaction is a reaction where heat or light energy is released. An example of this type of reaction is burning a candle.
Discuss the SN reaction with example?
The SN reaction is a substitution reaction. An example of the SN reaction is Br. H3CH2C.
How to convert aniline to picric acid?
React aniline with HCl/NaNO2 (diazotisation) followed by reaction with KOH to give phenol. Nitration of phenol with fuming nitric acid gives picric acid (or trinitrophenol).
What is striking a match an example of?
Striking a match is an example of an endothermic reaction. It is also an example of simple combustion and a chemical reaction.
Is photosynthesis an example of an endothermic reaction yes or no?
No, photosynthesis is not an example of an endothermic reaction. It is an example of an exothermic reaction because it releases energy in the form of glucose and oxygen.
