Abstract
PURPOSE: To separation-recover Pd as metallic Pd in a high yield by subjecting an arom. cpd. to oxidation coupling reaction in the presence of an org. Pd catalyst in a solventless state and mixing an alkali metal carbonate and a reducing agent into the resulting soln.
CONSTITUTION: An arom. cpd. such as benzene, toluene or xylene is dehydrogenation-dimerized in the presence of an org. Pd catalyst such as Pd salt of aliph. carboxylic acid in a solventless phase under a press. of 2W200kg/cm2 at a temp. of 40W300°C to form a biphenyl cpd. To the resulting soln. after the oxidation coupling reaction is added a carbonate such as Na2CO3, K2CO3 or Li2CO3, a hydrogencarbonate such as NaHCO3 or KHCO3 or other alkali metal carbonate in an amt. of 0.01W10g per kg of the soln., and they are mixed. After adding a reducing agent such as hydrogen gas, formic acid or oxalic acid the mixed soln. is agitated for 10minW10hr. Pd contained is deposited as large particles of 30μ or more and recovered in a high yield.
