Claim:
A process for preparing silicon compound products which have hydrocarbonoxy groups and have at least one unit of the general formula (1) H m Si(OR) n (OR′) o R″ p X 4-m-n-o-p (1) said method comprising reacting silicon compound reactants which have at least one unit of the general formula (2) H m+n Si(OR′) o R″ p X 4-m-n-o-p (2) with an alcohol of the general formula (3) ROH (3) in the presence of a catalyst which is a metal selected from the group consisting of Ni, Pd and Pt bound to a support material, where not more than one liter of solvent is used per mole of OR group formed and R is a monovalent hydrocarbon radical which has from 1 to 18 carbon atoms and is optionally substituted by OH groups, halogen atoms, silyl groups, siloxy groups, —CN, —COOR 1 , —OCOOR 2 , —CONR 3 R 4 , —OCONR 5 R 6 , —NR 7 CONR 8 R 9 , —SO 2 —R 10 , —OSO 2 —R 11 , —OP(OR 12 )(OR 13 ), where a carbon chain thereof is optionally interrupted by nonadjacent —(CO)—, —O—, —S— or —NR 14 — groups; R′, R″ are each a monovalent hydrocarbon radical which has from 1 to 18 carbon atoms and is optionally substituted by halogen atoms, silyl groups, siloxy groups, —CN, —COOR 1 , —OCOOR 2 , —CONR 3 R 4 , —OCONR 5 R 6 , —NR 7 CONR 8 R 9 , —SO 2 —R 10 , OSO 2 —R 11 , —OP(OR 12 )(OR 13 ), where a carbon chain thereof is optionally interrupted by nonadjacent —(CO)—, —O—, —S— or —NR 14 — groups; R 1 to R 14 are each a monovalent hydrocarbon radical which has from 1 to 18 carbon atoms and is optionally substituted by halogen atoms, X is a chemical bond via which radicals containing silicon atoms are bound, m is 0, 1, 2 or 3, n is 1, 2 or 3, m+n is 1, 2 or 3, o is 0, 1, 2 or 3, p is 0, 1, 2 or 3 and m+n+o+p is 1, 2, 3 or 4.
