| titleOfInvention | The production of isocyanate-functional organosilan |
| abstract | The present invention relates to general formula (4) OCN-R is prepared since the carbamate groups organosilan (CS) of general formula (5) 2 ‑SiR 3 (3‑x) (OR 4 ) x (4) method of isocyanate-organosilanes (IS), wherein introduce carbamate groups organosilan (CS), the carbamate groups organosilan (CS) is by making at least one general formula (6) NH in the presence of basic catalyst (K) comprising alkaline function 2 ‑R 2 ‑SiR 3 (3‑x) (OR 4 ) x (6) amino-organosilanes (AS) are reacted with the dialkyl carbonate (DAC) of at least one general formula (7) and are prepared, wherein before preparing the isocyanate-organosilanes (IS), it is completely or partially neutralized the basic catalyst (K) with acid (S), the proton transfer stage of the acid (S) has at most 4.0 pK a It is worth, wherein R 1 、R 2 、R 3 、R 4 、R 5 There is the meaning as described in claim 1 with x. |
