Abstract: cf. C.A. 52, 9014h. It was detd. that the failure of some hydrogenation condensations of PhCH(OH)Ac (I) with MeNH2 in the production of l-ephedrine is caused by the higher concn. of Fe present in tech. I. The optimum concn. for this reaction of Fe(OH)3 is 0.0025, for Ni(OH)2 0.005, and for Co(OH)2 0.015%. Concns. of Fe(OH)3 and Ni(OH)2 higher than 0.01% and of Co(OH)2 higher than 0.05% stop the reaction.
