<p>The process comprises (A) obtaining N-acetylcysteine form L-cystine, through the following steps: (i) acetylation of L-cystine in order to produce N-acetylcystine; (ii) electroreduction and desalination by electrodialysis of N-acetylcystine thus produced in order to obtain N-acetylcysteine; (B) obtaining N-acetylcysteine from L-cystine, through the following steps: (i) acetylation and desalination of L-cystine in order to produce N-acetylcystine; (ii) electroreduction of N-acetylcystine proceeding or not from prior step (i), in order to produce N-acetylcysteine; (C) obtaining N-acetylcysteine from L-cystine through the following steps: (i) electroreduction of L-cystine in order to produce L-cysteine; (ii) acetylation and desalination by electrodialysis of L-cysteine, proceeding or not from prior step (i), in order to produce N-acetylcysteine. N-acetylcysteine thus obtained has important applications in the pharmaceutical sector.</p> |
