Process for preparing (cyclo)aliphatic isocyanates

Abstract:

The present invention relates to a novel process for preparing (cyclo)aliphatic diisocyanates and triisocyanates by phosgenation of (cyclo)aliphatic diamines and triamines in the gas phase by accelerating the flow of at least one of reactants in the region where the reactants are mixed.

Abstract(Chinese):

本发明涉及通过加速混合反应物的区域中的至少一种反应物的流动，在气相中通过（环）脂族二胺和三胺光气化制备（环）脂族二异氰酸酯和三异氰酸酯的新方法。
