Acetonyl-acetophenone, C6H5.CO.CH2.CH2.CO.CH3, is produced by condensing phenacyl bromide with sodium acetoacetate with subsequent elimination of carbon dioxide, and on dehydration gives aa-phenyl-methyl-furfurane.
excess phenylalanine is broken down to fumarate and acetoacetate, both of which are part of normal energy metabolism.
It may be synthesized by condensing sodium acetoacetate with monochloracetic ester, the acetosuccinic ester produced being then hydrolysed with dilute hydrochloric acid (M.
It may be prepared by the hydrolysis of ethyl acetoacetate, or by passing carbon monoxide over a mixture of sodium acetate and sodium ethylate at 205Ã‚° C. (A.
In alcoholic solution it condenses with sodium acetoacetate to form (-methylumbelliferone, CtoH803 (A.
