The activated Raney =AE metal slurry catalysts (W. R. Grace Co.) employed in this study were primarily Ni and Co. Ra 2800 contains only Ni and Ra 2400 contains nickel along with chrome and iron promoters.

Trivia question... Does anyone know the significance of the numbers used by WR Grace to label the these four formulations of Raney Nickel?

W.R. Grace and Co. Raney =AE

2800, slurry, in H2O, active catalyst (Aldrich)

2400, slurry, in H2O, active catalyst (Aldrich)

3202, slurry, in H2O, active catalyst (Aldrich)

4200, slurry, in H2O, active catalyst (Aldrich)


After a few hours researching to no avail, I am really curious,
Thanks,
