| Acetoacetamide Usage And Synthesis |
| Chemical Properties | White to yellowish crystals | | Uses | Acetoacetamide is used as intermediate for different organic syntheses, mainly organic dyestuffs. Product Data Sheet | | Uses | Acetoacetamide was used in a study to assess the stability of artificial sweeteners- aspartame, acesulfame-K and binary sweetener blend of aspartame x acesulfame-K during storage. Acetoacetamide was also used in analysis of multiple sweeteners and their degradation products in lassi by HPLC. | | Uses | Acetoacetamide is a β-keto amide commonly used in building heterocyclic systems. It can be used in synthesizing various N-substituted acetoacetamides, that are primary precursors for several organic dyes and pigments. | | General Description | Acetoacetamide is a degradation product of acesulfame-K, sweetener. Acetoacetamide undergoes alkaline hydrolysis to form salt of acetoacetic acid. | | Flammability and Explosibility | Notclassified | | Purification Methods | Recrystallise the amide from CHCl3, or Me2CO/pet ether. It also crystallises from pyridine with 4mols of solvent. It is slightly soluble in H2O, EtOH and AcOH but is insoluble in Et2O. The phenylhydrazone has m 128o.
