Title: PROCESS FOR PREPARING ORGANOSILICON COMPOUNDS CONTAINING ORGANYLOXY GROUPS
Abstract:
The present invention relates to organyloxy groups comprising organosilicon compounds, a method for producing same and the production of substances which can be cross-linked to elastomers, so-called RTV-1 substances, characterised in that in a first step, a organosilicon compound (E) comprising at least one silanol group is mixed with a compound (B) containing at least two organyloxy groups, in the presence of a base (C1) selected from guanidines, amidines and lithium-containing bases, and allowed to react, and in a second step the thus obtained reaction mixture is mixed with a phosphorus compound (C3) comprising P=O groups.
