L-PAC or 1-phenyl-1,2-propane dione?
Hi, please help on the choice of substances intended for the hydrogenation of d-ephedrine hydrochloride. I have to choose between these two
ingredients: l-phenylacetylcarbinol or 1-phenyl-1 ,2-propane dione.
l-phenylacetylcarbinol seems to me that it was standard procedure for the simple hydrogenation of methylamine in the environment 2.5 on palladium
catalyst for a better and more efficient choice.
What is your opinion on this?
(sorry for my English is not very good)

I have a chance to test (1-phenyl-1 ,2-propane dione) or L-phenylacetylcarbinol.
L-phenylacetylcarbinol is specifically designed for my hydrogenation reactor.
1-phenyl-1 ,2-propane dione is designed for different hydrogenation process, which can not be found. Reportedly, in the practical part better than the
L-PAC, but I can not compare in practice.
