Ethanal Ethanoic Anhydride

Its chief importance is as a source of cinnamic acid by condensation with sodium ethan-oate and ethanoic anhydride and as a source of triphenylmethane dyestuffs by condensation with pyrogallol, dimethylaniline, etc. It is also used in the manufacture of perfumes. [Pg.54]

Interestingly, it is often convenient during the manufacturing process of ethanoic anhydride [acetic anhydride, (CH3C0)20] to generate the ethanal (acetaldehyde, CH3CHO) itself on the same site in a separate, palladium(II) chloride (PdCy, catalyzed oxidation of ethene (ethylene, CH2=CH2) as shown in Scheme 9.133 (the Wacker process). ...

Scheme 9.132. A representation of the Mn -catalyzed oxygen (O2) oxidation of ethanal (acetaldehyde, CHaCHO) to perethanoic acid (peracetic acid.CHaCOaH) and the snbseqnent transformation of the peracid and additional ethanal (acetaldehyde, CH3CHO) to ethanoic acid (acetic acid, CHaC02H), via a Baeyer-Villiger transformation, or to ethanoic anhydride [acetic anhydride, (CHaCO)20].
