Acetic anhydride
Without precipitate Formation of layers
Table 3 shows the tabulated results of Aminolysis
Hydroxamic Acid Test Preliminary Test
Observations Yellow Solution is obtained Deep burgundy color Orange-red color
Acetyl Chloride exhibited formation of white precipitate upon addition of 0.5ml anilline. Acetic Anhydride however did not form any precipitate, but it did form layer.
Ethyl Acetate Acetamide
4. Hydroxamic Acid test
A Preliminary test was done to eliminate those phenols and enols that give colorswith ferric chloride in acidic solution that would therefore give false positive result in the ferric hydroxamic test Ethyl acetate yielded deep burgandycolor which was a positive result Acetamide gave an orange-red color which is also a positive result
Table 4 shows the tabulated results of Hydroxamic Acid Test
