N-methylformamide function
WebUsing the Kirkwood–Buff theory of solutions, the preferential solvation of the N -methylacetamide molecule has been investigated in the binary and ternary mixtures containing N -methylacetamide (NMA), aliphatic alcohol and water. The results are compared with those obtained previously for N -methylformamide (NMF) and N, N … WebTwo routes commonly used in Europe and the U.S.A., the Leuckart and reductive amination with aluminum/mercury (Al/Hg) amalgam techniques, both require 1-phenyl-2-propanone (P2P) as the starting material (see Figure 1). The route specific impurities for the two methods utilizing P2P within a single controlled study will be discussed in this paper.
