[Hydrolysis of keratin products using some of sulfonic acids. Isolation of hydrolysing factors from hydrolyzates].
The term of isolation of arylosulfonic acids as hydrolysing factors from casein's hydrolyzates have been worked out. The most satisfactory results have been achieved when using in this case chloride 2,3,5-triphenylo-2H-tetrazole. When using benzenosulfonic acid as the best hydrolising factor 98.4% of this acid was removed from hydrolysates of hoofs whereas 96.1% was removed from hydrolysates of bristles. The residues of acids remaining in hydrolysates have been removed by shaking with Wofatyt SBW in form H+. The total recovery of aminoacids irrespectively to kind of hydrolyzate and applied acid amounts to 95.5% average.
