The present invention relates to a new process for preparing polyisocyanates containing isocyanurate groups and being flocculation-stable in solvents from (cyclo)aliphatic diisocyanates.

Method for producing polyisocyanates of (cyclo)aliphatic diisocyanates which are flocculation-stable in solvents

The present invention relates to novel color drift-stable compositions of polyisocyanates of (cyclo)aliphatic diisocyanates.

Colour-stable curing compositions containing polyisocyanates of (cyclo)aliphatic diisocyanates

The present invention relates to a novel process for preparing isocyanurate-comprising polyisocyanates of (cyclo)aliphatic diisocyanates that are especially stable to color drift in solvents.

The present invention relates to a process for preparing at least one monocyclic ketone having from 4 to 20 carbon atoms by reacting a mixture Gcomprising at least one monocyclic olefin having from 4 to 20 carbon atoms with a mixture Gcomprising at least dinitrogen monoxide, wherein said reaction is performed adiabatically.

Process for preparing cyclic ketones

Process for the preparation of cyclododecanone

A process for preparing cyclopentanone, at least comprising the following steps (i) to (iii):

Method for the production of cyclopentanone

The present invention relates to a process for purifying a gas mixture comprising dinitrogen monoxide and to the use of a gas mixture purified in this way as an oxidant for olefins. In a further embodiment, the present invention also relates to a process for preparing ketones comprising the oxidation of an olefin with a gas mixture which has been purified in accordance with the invention and comprises dinitrogen monoxide.

Method for purifying and concentrating dinitrogen monoxide

A process for preparing a ketone, in particular cyclododecanone, by reacting cyclododecatriene with dinitrogen monoxide to obtain cyclododecadienone and hydrogenating the resulting cyclododecadienone, in particular to give cyclododecanone.
