A catalyst based on Fe(OH)3 for the low-temp. conversion of ortho-H into para-H is prepd. by pptg. the hydroxide at a high temp. in a weakly alk. medium, holding the hydroxide residue in the mother liquor at a high temp., washing off accompanying ions from the residue, and drying at a high temp. To prep. a highly active catalyst, Fe(OH)3 is pptd. together with Al(OH)3 in an at. ratio of Fe/Al 0.3-9, preferably 0.3-3, at 15-30°; the residue is held in the mother liquor at 15-80°; and the washed and dried residue is roasted and reduced in a H flow at 400-600°.
