| 1.1.1.71 | KCl |
maximally active with ethanol with 4 M KCl. It is maximally active with 1-propanol with 2 M KCl and with 1-butanol and 1-pentanol with 1 M KCl. Optimum activity with the secondary alcohols, 2-propanol and 2-butanol, is observed with 3 M KCl and 2 M KCl, respectively, and with isoamyl alcohol in the presence of 1 M KCl. Maximum activity with benzyl alcohol is detected with 2 M KCl. Catalyzed the reductive reaction optimally at pH 6.0 with 1 M KCl |
