Abstract:
PCT No. PCT/DE88/00049 Sec. 371 Date Mar. 31, 1989 Sec. 102(e) Date Mar. 31, 1989 PCT Filed Feb. 2, 1988 PCT Pub. No. WO88/05778 PCT Pub. Date Aug. 11, 1988.Described is a process for producing oximosilanes having the general formula (I) R1a Si(O-N=Cr2R3)4-a (I) wherein R1 represents a straight-chain or branched alkyl residue having between 1 and 18 carbon atomns, a straight-chain or branched alkenyl residue having between 2 and 18 carbon atoms, an aryl or aralkyl residue optionally substituted by halogens, nitro groups, amino groups and/or alkyl residues having between 1 and 4 carbon atoms, or a straight-chain or branched alkoxy-residue having between 1 and 8 carbon atoms, a is an integer of 0 to 3, and R2 and R3, independently of each other, represent straight-chain or branched alkyl residues having between 1 and 18 atoms, optionally substituted by halogens, nitro groups, amino groups and/or alkyl residues having between 1 and 4 carbon atoms, by reacting an acyloxisilane with an oxime in molar excess, characterized in that an acyloxy-silane of general formula (II) R1a Si(OCOR4)4-a (II) wherein R1 and a have the above mentioined significations and R4 represents straight-chain or branched alkyl residues having between 1 and 18 carbon atoms, preferably between 2 and 8 and more preferably between 2 and 4 carbon atoms, straight-chain or branched alkenyl residues having between 2 and 18 carbon atoms or aryl or aralkyl residues optionally substituted with halogens, nitro groups, amino groups and/or alkyl residues having between 1 and 4 carbon atoms, with a ketoxime having the general formula (III) wherein R2 and R3 possess the above significations, in the absence of an acid acceptor, while distilling off the carboxylic acid, which is released from the acyloxisilane of the general formula (III).
