Application

Suitable as a hydrogenation catalyst for aromatic, olefin, nitrile and nitro group reductions.
Used as reducing agent for hydrogenation of organic compounds, e.g. hydrogenation of nitriles to amines, reduction of aromatic groups to the corresponding saturated compounds, hydrogenation reaction of β-keto esters, rreduction of amination, and also used as 3-alkylation of oxindole with alcohol, and Ullman-type cross coupling, and dehalogenation reactions.

  3. What is the W classification of Product 221678, Raney®-Nickel - W.R. Grace and Co. Raney®2800, slurry?

    1 answer

    1. The numbers W1 through W8 were various activation treatments as part of a study conducted by Dr. Atkins at the University of Wisconsin. The publications date from 1932 to 1955. Although the commercial products of today are not processed as shown in the study, the Raney® nickels that we carry most closely match the 'W-2' form because they are all activated and stored in water.
