Abstract: Ortho- or para-monoalkylated phenols or 2,4- or 2,6-dialkylphenols can be produced from phenolic compounds in good yields and in the absence of isomers. The starting phenol which has at least two available ortho or para positions unsubstituted is converted to a t-alkylated phenol having at least one ortho or para position unsubstituted. The desired t-alkylated phenolic compound is reacted with an aldehyde having one to four carbon atoms and a secondary aliphatic or alicyclic amine. The reaction is conducted in the liquid phase with a stoichiometric amount of the phenolic compound and stoichiometric or excess of stoichiometric amounts of the aldehyde and the secondary amine. The reaction is conducted at a temperature in the range of about 0.degree. C., to about 100.degree. C. and the reaction produces an aminoalkylated t-alkylated phenol. The aminoalkylated phenol is contacted with hydrogen in the presence of a metal catalyst at a temperature of about 100.degree. C. to about 175.degree. C.

Abstract: 1-Methylene carbonyl derivatives of 3-aryloxy-4-phenyl-azet-2-ones are effective plant-growth regulators.

Abstract: A process for the preparation of aniline by reaction of alicyclic alcohols or ketones with ammonia in the presence of a crystalline silicate catalyst having the structure of ZSM-5. Especially preferred alicyclic charge stocks are the mononuclear naphthenic type compounds such as cyclohexanol and cyclohexanone or mixtures thereof.

Abstract: Primary amines and/or diamines can be prepared from oxo compounds, optionally containing additional reducible groups, by a process comprising:(1) reacting the oxo compound with ammonia in the presence of an imine-forming catalyst, preferably an ion exchanger loaded with ammonia ions, at a temperature of 10.degree. to 120.degree. C. and a pressure of 1 to 300 bar, whereby a Schiff base is formed; and(2) reducing the Schiff base by reaction with ammonia and hydrogen in the presence of a hydrogenation catalyst.

Abstract: Aromatic amines, in particular substituted amines, are obtained from corresponding alicyclic alcohols or ketones, in one step, by amination and dehydrogenation with ammonia in the presence of hydrogen and of a palladium catalyst which also contains zinc or cadmium.

Abstract: A process for alkylating a polyamine by contacting, in a liquid media, a polyamine, an olefinic compound, carbon monoxide, and a hydrogen source in the presence of a catalytic amount of a rhodium atom containing compound selected from metallic rhodium, rhodium salts, rhodium oxides, rhodium carbonyls and ligands thereof at a temperature of from about 50.degree. C. to 250.degree. C. and at a pressure of from about 30 to about 300 atmospheres.

Abstract: A process for forming amines by contacting, in a liquid media, an olefinic compound, carbon monoxide, water, and ammonia in the presence of a rhodium atom containing compound selected from metallic rhodium, rhodium salts, rhodium oxides, and rhodium carbonyls and ligands thereof at a temperature of from 50.degree. to 250.degree. C. and at a pressure of from about 10 to about 300 atmospheres.

Abstract: The desired compounds, namely, N-phenyl-N'-alkylphenylenediamines, are prepared by the reductive alkylation of a nitrogen-containing diphenylamine and a ketone in the presence of hydrogen and a hydrogenation catalyst. The desired product may be obtained in a more economical way when effecting the process in a continuous manner by utilizing an organic solvent for the reaction which comprises an ether compound such as a monoether of a dihydric alcohol, a diether of a dihydric alcohol, or a cyclic diether.
