It is a particular advantage of this procedure that it is possible to carry out both the attachment of the fragrance and the condensation in a reaction stage, the water released causing the condensation of the alkoxysilyl groups. Another advantage of this process variant is that higher temperatures are avoided by the fact that the water does not need to be removed, which allows the economic production of very pure products and expensive separation steps to remove unwanted entrained residual contaminants or decomposition products dispensable.
- the amount of alkoxysilyl groups remaining in the final product can be controlled, and thus, the reactivity to certain substrates are obtained or controlled.
