Trimethylolpropane of high purity is efficiently made by mixing the aldol reaction product of formaldehyde and n-butyraldehyde with at least about 20 wt % of a lower alcohol prior to hydrogenation. The alcohol addition also promotes hydrogenolysis of by-product esters at pressures below 3000 psig and allows recovery of high purity product by simple distillation.

Manufacture of trimethylolpropane

Neopentyl glycol is made from isobutyraldehyde and formaldehyde. The formaldehyde may be in the form of paraformaldehyde or aqueous formaldehyde. The aldol reaction product is mixed with a lower alcohol prior to hydrogenation to promote hydrogenolysis and allow recovery of high purity product by simple distillation. In a less preferred mode, the alcohol may be added after hydrogenation, resulting in a smaller improvement over previous processes.

New polymers are disclosed to be made in supported Ziegler-Natta systems. They include monomers exhibiting polar functionality such as through a hydroxyl group or other functional group protected during polymerization in the presence of highly active catalysts by the use of a protective alkyl silane group which is removed after polymerization to restore the functionality of the group. The typical polymer thus made is a polyolefin having functional groups on its backbone; the functional groups may be reacted with conventional dyes and/or may perform other functions and enter reactions with other reactive compounds.

Incorporation of functional groups in polymers

Mono and diallyl amines are silylated to protect them from reacting with high activity Ziegler-Natta catalysts so they may be copolymerized with propylene; also disclosed are copolymers of such amines with propylene and their hydrolyzed or alcoholyzed counterparts.

Method of making amine/propylene copolymers

Mono and diallyl amines are silylated to protect them from reacting with high activity Ziegler-Natta catalysts so they may be copolymerized with propylene; copolymers of such amines with propylene and their hydrolyzed or alcholyzed counterparts; also the amine monomers disclosed.

Amine/propylene copolymers

Phenolic compounds, particularly phenol, are aminated by reaction with ammonia in the presence of a catalyst made by calcining bayerite.

Catalyst and process for making aniline from phenol

Magnesium/aluminum synthetic anionic clay catalysts are made by spray-drying a slurry of a Mg/Al synthetic clay, making a plasticized mixture of the spray-dried clay with diatomaceous earth, forming, drying and calcining the formed dried mixture. The catalyst is useful for making isophorone by the condensation of acetone.
