Question

Scrieti o serie de reactii prin care se obtine anhidrida acetica pornind de la etena.

Answer 1

CH2=CH2 (etena) + H2O => CH3-CH2OH (alcool etilic)
CH3-CH2OH + 2[O] (in prezenta de KMnO4/H2SO4) => CH3-COOH (acid acetic) +H2O
CH3-COOH + PCl5 (pentaclorura de fosfor) => CH3-COCl (clorura de acetil) + POCl3 + HCl
CH3-COCl + CH3-COONa (acetat de sodiu) => (CH3-CO)2O (anhidrida acetica) + HCl
