A process for racemization of optically active amino alcohols by subjecting the amino alcohol to hydrogen under moderate temperature and pressure conditions while in contact with Raney cobalt.

Racemization of optically active amino alcohols

A process of forming 2-amino-1,3-propanediol by reducing the compound, 5-nitro-1,3-dioxane and subsequently hydrolyzing the reduced compound.

Novel process for the preparation of serinol

A homogeneous catalytic hydrogenation of nitroalcohols to amino alcohols is described in which a solution of nitroalcohol is contacted with hydrogen under low temperatures and in the presence of a soluble complex of an organometallic compound of Rh, Ir, Pt or Pd and an organophosphine.

Reduction of nitroaliphatics via homogeneous catalysis

A process of forming N,N-dialkylhydroxylamines (a class of compounds useful as oxygen scavengers in boiler water feed) by contacting an N-alkylhydroxylamine with an alkyl carbonyl compound to form a nitrone in situ or, alternatively, using previously formed alkylnitrone which is subjected to H.sub.2 and a hydrogenation catalyst.
