Abstract
Compounds having polyether chains terminated by primary or secondary amine groups are prepared by the reductive amination of the corresponding ketonic compounds X-[-(CHR-CHR-O)m-(CHR-CHR1-O-)n-CHR-COR1]a where R is hydrogen or a hydrocarbon group, R1 is a hydrocarbon group, n is at least one, and m is zero or an integer, and X is the residue of a compound XHa containing 2 hydrogen atoms reactive towards cyclic oxides. The reductive amination involves the simultaneous treatment of the ketonic polyether with ammonia or a primary amine and a ketone-reducing agent, such as sodium amalgam, formic acid or zinc/acetic acid, or, in particular, hydrogen with a catalyst. The preferred catalyst is Raney nickel, but Raney cobalt, or cobalt on kieselguhr may be used. When hydrogen is used temperatures of 40-150 DEG and pressures of 50-250 atmospheres are preferred. Excess of ammonia or amine is used in order to minimize chain linkage by amine groups. Suitable amines include aliphatic, alicyclic, aromatic and heterocyclic primary amines and polyamines, e.g. methylamine, ethanolamine, tolylene diamine. The examples describe the reactions of a ketone ended polypropylene oxide of molecular weight about 1,000 with ammonia, and with ethanolamine under hydrogen in the presence of Raney nickel. Specification 971,173 is referred to.ALSO:Compounds having polyether chains terminated by primary or secondary amine groups are prepared by the reductive amination of the corresponding ketonic compounds X-[-(CHR-CHR-O)m-(CHR-CHR1-O)n-CHR-COR1]a where R is hydrogen or a hydrocarbon group, R1 a hydrocarbon group, n is at least one, and m is zero or an integer, and X is the residue of a compound XHa containing 2 hydrogen atoms reactive towards cyclic oxides.
