dc.description.abstract | Deprotenizace chromitého koláče získaného po enzymatické hydrolýze chromočiněných postružin byla provedena alkalickou hydrolýzou v tlakové nádobě roztokem KOH. Kinetika podle provedených výpočtů odpovídá s dobrou shodou reakci II. řádku; efektivní hodnota rychlostní konstanty k= 8,9.10 na -3 l /(mol.s) a aktivační energie Ea = 130kJ/mol při teplotě hdrolýzy 116°C. | cs |
dc.description.abstract | After enzymatic hydrolysis chrome-tanned shavings and subsequent filtration, cake is formed, composed of hydrated Cr2O3 with protein products of hydrolysis as well as with non-hydrolysable fraction. After hydrolysis with KOH was evaluated hydrolysis kinetics. Formal kinetics of this alkaline hydrolysis | en |
dc.description.abstract | appears to agree with a second-order reaction, with effective values of rate constant c=3.9 .10 na-3 l/(mol.s) and activation energy Ea = 130 kJ/mol at a temperature of 116°C. | en |
