This invention relates to an improvement in a liquid phase process for producing isopropanol by the hydrogenation of acetone in the presence of a hydrogenation catalyst; the improvement comprising;

Hydrogenation of acetone

This invention relates to a process for the preparation of 1,1-difluoroolefins, e.g., difluorovinyl cycloaliphatic compounds such as difluorovinylcyclohexane and derivatives by the dehydrofluorination of a trifluoromethyl-substituted cycloaliphatic compound and the resulting compositions. This method utilizes a 'sterically hindered super-base' system represented by the formula MNRR; where M is Na or K and R is a secondary, or tertiary alkyl or cycloalkyl group of amines for effecting dehydrofluorination of the trifluoromethyl group leading to the difluorovinyl based cycloaliphatic compounds. The sterically hindered super base can be formed by the, in situ, reaction of a sodium or potassium alkoxide, e.g., KtBuO with a lithium dialkylamide where the lithium is bonded to nitrogen atom of an amine bearing secondary or tertiary aliphatic groups.

A method of preparing vicinal difluoro aromatic compounds in high yield from hydroxy aromatic compounds using various bases and a method of preparing intermediates thereof. A method for making a vicinal difluoro halogenated aromatic compound including providing a tetrafluoro derivative of a halogen substituted aromatic compound, wherein the tetrafluoro derivative has two fluorine atoms on each of two adjacent carbons and at least one additional halogen substituent; reacting the tetrafluoro derivative with a reducing agent in presence of a base for a reaction time sufficient to form the vicinal difluoro halogenated aromatic compound containing two vicinal fluorine substituents and the at least one additional halogen substituent, wherein the reducing agent is used in a reducing agent effective amount sufficient to retain the at least one additional halogen substituent.

Synthesis of vicinal difluoro aromatics and intermediates thereof

A method of preparing vicinal difluoro aromatic compounds in high yield from hydroxy aromatic compounds and a method of preparing intermediates thereof. The hydroxy aromatic compound can be a mono-, bi- or tricyclic aromatic in which the rings are separate or fused. One or more of the rings can contain heteroatoms, such as oxygen, nitrogen, or sulfur, and can contain one or more substitutions, in addition to the hydroxy substitution.

A method for racemizing an enantiomer of an alkoxyamine represented by formula I ##STR1## in which R.sub.1 and R.sub.2 are the same or different C.sub.1 to C.sub.20 alkyl group. A feed containing an enantiomer of the alkoxyamine is passed over a nickel or cobalt catalyst in the presence of hydrogen and ammonia. The racemic mixture formed by this method contains substantially no by-products.

Racemization of optically active alkoxyamines

A process for the production of aliphatic amines by reacting aliphatic alcohols with an amino compound in the presence of a catalyst containing at least two inter-dispersed metals, in a multi-metallic structure, in which at least one of the metals is nickel or cobalt, and at least one other metal is palladium, platinum, rhodium, ruthenium, or copper.

Disclosed is an improved process for the catalytic hydrogenation of cyanopropionaldehyde alkyl acetals (CPAA) to form the aminobutyraldehyde alkyl acetals. The basic process comprises hydrogenating the cyanopropionaldehyde alkyl acetals by contacting said cyanopropionaldehyde alkyl acetals with hydrogen in the presence of a nickel or cobalt catalyst under conditions for reducing the nitrile group to the primary amine. The improvement resides in effecting the hydrogenation of a cyanopropionitrile dialkyl acetal feedstock containing contaminating levels of cyanopropionaldehyde in the presence of a secondary alkanol or water.
