(OH)2. Anhydrides of organic acids have many uses. They react with alcohols to form esters; e.g., acetic anhydride, (CH3CO)2O, reacts with ethanol, C2H5OH, to form ethyl acetate, CH3COOC2H5, a useful solvent. They also react with ammonia and primary or secondary amines to form amides...

Furthermore, fermentation of glucose to yield succinic acid has distinct advantages. While during bioethanol production, for example, 2 mol of inert waste CO2 per mole of glucose are formed, biosuccinic acid production is a CO2-fixing operation:31 Bioethanol fermentation:C6H12O6→2C2H5OH+2CO2 Bio...
