Hydrogen peroxide prepn. from oxygen and hydrogen in aq. soln.

摘要

Reaction between O2 and H2 to form H2O2 is at super-atmos. pressure, in aq. medium substantially free of organic material with Pd on adsorbent carbon as catalyst. Pd is at least 0.5% of wt. of C + Pd and pref. over 2%. Catalyst is pref. prepd. in situ by addn. of finely divided carbon to a Pd salt in soln. contg. hydrogen and chloride ions at concns. separately of 0.01-2 M.
