Preparation of primary and secondary amines from nitriles

Hydraulic fluids, in particular brake fluids for motor vehicles, comprising from 0.01 to 50 wt % of one or more cyclic carboxylates, or cyclic carboxamides, which can carry a linear or branched C -bis C alkyl group on the nitrogen atom.

Hydraulic fluids, containing cyclic carboxylic acid derivatives

Preparation of amines

Oligomer mixtures derived from cyclopentene; method for the production and use thereof

Pure triethylenediamine (TEDA) is prepared by vaporizing TEDA, introducing the gaseous TEDA into a liquid solvent and subsequently crystallizing the TEDA from the solution obtained in this way.

Preparation of pure triethylenediamine

Racemization of optically active amines

Monoisopropylamine is prepared by reacting acetone with ammonia and with hydrogen at elevated temperature and elevated pressure in the presence of a catalyst, wherein the catalytically active mass of the catalyst comprises, after its preparation and before the treatment with hydrogen, from 20 to 90% by weight of aluminum oxide (Al O ), zirconium dioxide (ZrO ), titanium dioxide (TiO ) and/or silicon dioxide (SiO ), from 1 to 70% by weight of oxygen-containing compounds of copper, calculated as CuO, from 1 to 70% by weight of oxygen-containing compounds of nickel, calculated as NiO, and from 1 to 70% by weight of oxygen-containing compounds of cobalt, calculated as CoO.

Preparation of pyrrole and pyridine

Preparation of secondary amines from nitriles

Process for preparing amines

A process for preparing polytetrahydrofuran, polytetrahydrofuran copolymers or diesters or monoesters of these polymers comprises polymerizing tetrahydrofuran in the presence of at least one telogen and/or comonomer over a heterogeneous catalyst comprising hectorite.

Method for producing polytetrahydrofuran

In the process for preparing formamide by reaction of ammonia and carbon monoxide in the presence of at least one catalyst, sodium diformylamide is used as catalyst. If sodium methoxide is used as further active component, sodium diformylamide can be formed from this. In this process, sodium diformylamide is a particularly active and stable catalyst which can be recycled.
