Abstract: The invention is directed to an improved, reliably performable process for preparing triallyl isocyanurate (TAIC) by Cu2+-catalysed rearrangement of triallyl cyanurate (TAC) at at least 90°C. According to the invention, TAC and, if required, also a Cu2+ catalyst and solvent are fed continuously to a start reaction mixture after onset of the initially inhibited isomerization reaction, the isomerization is performed at from 90 to 160°C and an amount of reaction mixture equivalent to the amount of reactant is drawn off continuously and sent to the workup. Preference is given to effecting the isomerization in TAIC as the reaction medium.

Abstract: Preparation of triallylisocyanurate comprises rearranging triallylcyanurate in the presence of copper (II) salts (0.01-1 wt.%) at at least 90[deg]C, preferably 90-160[deg]C; introducing separately or in a mixture of triallylcyanurate and copper (II) salts into the triallylisocyanurate; cooling the reaction mixture at less than 90[deg]C; continuously adding the reaction mixture and isolating the triallylisocyanurate from the reaction mixture.

Abstract: A process for the production of primary and/or secondary amines from imines or nitriles, comprising an aminating hydrogenation of imine or of nitrile with hydrogen in the presence of ammonia, of a hydrogenation catalyst based on cobalt, nickel, ruthenium or mixtures of these metals and of a base, at a temperature within the range of 50 DEG C. to 200 DEG C. and at a pressure within the range of 0.3 to 30 MPa. The yield of amine is increased by the use of a quaternary ammonium hydroxide as base. Preferably a tetraalkylammonium hydroxide is used in a quantity of from 0.01 to 100 mMol per mol of amine or of nitrile. The process is suitable in particular for the production of isophoronediamine from isophorone nitrile imine.

Abstract: A process for the production of primary and/or secondary amines from imines or nitriles, preferably for the production of 3 monomethyl-3,5,5-trimethylcyclohexylamine (isophoronediamine) from 3- cyano-3,5,5-trimethylcyclohexane-imine (isophoronenitrile-imine) is claimed. The imine or nitrile is subjected to an amination-hydrogenation process using hydrogen in the presence of ammonia, a cobalt, nickel and/or ruthenium based hydrogenation catalyst and a hydroxide base at 50-250 deg C and 0.3-30 MPa and work up of a the reaction mixture. The amination-hydorgenation process is carried out in the presence of a quat. ammonium hydroxide.
