  • Why is acetic acid used in acetylation?

    So the reason why Acetic acid is used is to polarise the Bromine molecule to bromine atoms with first of all partial negative and positive charge and finally formation of +ve and -ve bromine atom. Proteins that replicate DNA and repair damaged genetic material are created directly by acetylation.

  • Can acetic acid be used in acetylation?

    Acetylation has been carried out by using acetic anhydride in acetic acid, and it has been shown that the acetylation of the hydroxyl group takes place together with the hydrolysis of the cellulose chain, yielding a reduction of the diameter of treated CNCs (Sassi & Chanzy, 1995).

  • Is acetic acid used as a catalyst?

  • Glacial acetic acid is used because it is an excellent polar protic solvent capable of dissolving acetanilide. For the process, acetanilide is first dissolved in the solvent, glacial acetic acid, by warming. It's just a solvent to dissolve anisole (both are polar).
