Abstract
Procedeul de obtinere a cistinei, conform inventiei, consta în aceea ca lîna se trateaza cu acid sulfuric 50%, solutia se încalzeste 4 h la reflux, se raceste si se adauga apa pîna la obtinerea a 10 volume, se filtreaza si apoi se trece pe un schimbator de ioni anionic slab bazic, se concentreaza iar si se aduce la pH acid, se filtreaza si dupa sedimentare se purifica prin recristalizari.
