Method for producing organosilicon compounds having amino groups

The object of the invention is therefore to provide a method for the preparation of amino-functional polyorganosiloxanes, in which (A) organosiloxanes containing Si-OH groups are reacted with (B) at least stoichiometric amounts of monoalkoxy(aminoalkyl) silanes with respect to the Si-OH groups, wher...

Beschreibung
Zusammenfassung:	The object of the invention is therefore to provide a method for the preparation of amino-functional polyorganosiloxanes, in which (A) organosiloxanes containing Si-OH groups are reacted with (B) at least stoichiometric amounts of monoalkoxy(aminoalkyl) silanes with respect to the Si-OH groups, wherein catalytically active additives selected from acid, base or metal-organic compound are used in amounts of less than 0.1 ppm acid, less than 30 ppm base and less than 0.4% metal-organic compound.
