| 摘要 |
The invention relates to a method for producing isocyanato-organosilane of general formula (I) R<2>R<3>R<4>Si-R<1>-N=C=O. According to said method, gaseous carbamato-organosilane of general formula (II) R<2>R<3>R<4>Si-R<1>-NH-CO-OR (II), wherein R represents a monovatlent C1-C10 alkyl radical, R<1 >represents a bivalent C1-C6 hydrocarbon radical and R<2>, R<3 >and R<4 >respectively represent a methyl, ethyl, n-propyl, i-propyl, methoxy, ethoxy, n-propoxy or i-propoxy radical, is heated in the presence of a heterogeneous catalyst.
