When two molecules of acetic acid undergo a condensation reaction together, the product formed is acetic anhydride. Acetic Acid as a Solvent In its liquid state, CH3COOH is a hydrophile (readily dissolves in water) and also a polar, protic solvent. A mixture of acetic acid and water is, in...
Acetic Anhydride:Acetic anhydride is the result of the condensation of two acetic acid molecules. Significant use is the worldwide processing of acetic anhydride, utilizing about 25 per cent to 30 per cent of global acetic acid production. The key method includes acetic acid dehydration to give ...
(see the section on spacer arms, this chapter). The final coupling of the iodoacetate molecule onto the amino spacer can be performed using iodoaceticanhydrideor NHS-iodoacetate, or through acarbodiimide(EDC) coupling procedure to attach the carboxylate to the amine through an amide bond.Malliket...
