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

Dimethylformamide synthesis via reactive distillation of methyl formate and dimethylamine

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

This invention pertains to an improved process for preparing noncyclic polyalkylene polyamine compounds in high selectivity by reacting an alkanolamine and an alkylene amine in the presence of an acidic catalyst. The improvement resides in effecting the reaction under fixed bed catalytic conditions and maintaining the reaction conditions such that a vapor phase condition exists for the reaction mixture comprising both reactants and products. To accomplish the formation of vapor phase conditions, sufficient alkylenediamine is injected into the feedstream along with alkanolamine, temperature is maintained from 200.degree.-280.degree. C., and pressure ranges from about 0 psig to 150 psig so that the dew point temperature of the reaction product mix is below the reaction temperature at reaction pressure.

Polyalkylene polyamines via vapor phase reaction

This invention pertains to an improved process for preparing noncyclic polyalkylene polyamine compounds in high selectivity by reacting an alkanolamine and an alkylene amine in the presence of an inert gas and an acidic catalyst. The improvement resides in effecting the reaction under fixed bed catalytic conditions and maintaining the reaction conditions such that a vapor phase condition exists for the reaction mixture comprising both reactants and products. To accomplish the formation of vapor phase conditions sufficient inert gas is injected into the feedstream along with alkanolamine and alkylene amine so that the dew point temperature of the reaction product mix is below the reaction temperature at reaction pressure.

Polyalkylene polyamines via vapor phase reaction using inert gas

In a process for the preparation of alkylamines which comprises contacting an alkanol feed having at least three carbon atoms with ammonia in the presence of a hydrogenation catalyst and hydrogen in a reaction zone to yield a product effluent stream, separating the product effluent stream into an alkylamine stream for distillation and a vent stream comprising hydrogen and hydrocarbon by-products, the method comprising
