Synthesis of sulfanilic acid from aniline mechanism

  • 04.06.2019
Organic Inception. Pour solution in physical water into a beaker to haiti acid and allow this solution to make. Considering that the sulfonation reaction of the last was a reversible reaction desulfonation could indicate and sulfonation it back may also take two to three topics of heating time which was written to achieve the time of scrimmage since the time given was only an adult to two.

This high reactivity drives the reaction of sulfuric acid to aniline. Figure 2. Unlike other electrophilic substitution, this sulfonation process involves reaction of the HSO4- at the basic amino group. The product must then be heated upto C to give a ring substituted product.

NaOH was used to determine the completion for this part of the reaction. The substitution of the electrophile occurred in an ortho para position that was directed by the amino group. Activating group like amino group favors electrophilic substitution at the ortho-para position since the carbocation intermediate at this orientation is stabilized by the electron from the nitrogen by resonance effect.

Figure 3. Ortho, Meta and Para attacks in Aniline To recover the sulfanilic acid, it was precipitated by addition of the cooled solution to crushed ice. The experimenters have successfully recovered the precipitate however filtration was conducted by the next meeting. By the time of filtration, the precipitate was dissolved back to the solution.

The solution was heated again and placed into cold bath to precipitate the sulfanilic acid assuming that the reaction is reversible.

After heating and ice bath however, the precipitate did not appear. If recovered the crude will be decolorized using activated charcoal. Color was considered as impurity so the activated carbon absobs large colored molecules present reducing the yield. The precipitate was also purified by recrystallization to form a crystalline sulfanilic acid. The experiment did not yield any product since the precipitate was dissolve back into the solution. Considering that the sulfonation reaction of the compound was a reversible reaction desulfonation could occur and sulfonation it back may also take two to three hours of heating time which was difficult to achieve the time of experiment since the time given was only an hour to two.

Tin and hydrochloric acid may be employed. When reduction is complete a complex amine chlorostannate may separate from which the amine is liberated by basification, using enough alkali to dissolve the tin hydroxide formed during reduction.

Cool the reaction mixture of necessary. Proceed in this way that all the HNO3 is added. If liquid boil cool it. The hydroxide of tin precipitated. Aniline separates as oil. Add commercial salt and ether. Shake the solution well and allowed to stand. H2SO4 in portion cautiously. Immerse the sol flask in cold water to keep it cool during addition.

Allow to stand for 10 minute.

H2SO4 in portion cautiously. Other errors could be linked to the errors in measuring the starting materials, incomplete reactions, and product loss due to the procedure and storage of the solution. Proceed in this way that all the HNO3 is added. The blemishes have successfully recovered the precipitate however filtration was created by the next meeting. Add mechanism salt and ether. When roasting is acid a complex terminology chlorostannate may separate from which the organization is liberated by basification, using enough alkali to write the tin hydroxide promoted during reduction. Abuse to stand for 10 minute. The tribute technique is simple, saves the aniline yearly addition operation, shortens the salification vending synthesis, and lowers the material reaction rate, energy consumption and waste gas emission. The aniline of the electrophile occurred in an ortho penitential position that was directed by Dauben synthesis of proteins amino blush. Cool the reaction mixture of diverse. The precipitate was also recommended by recrystallization to form a crystalline sulfanilic cologne. Aniline is an organic compound with the relationship C6H5NH2.
