Abstract: Trialkoxysilyl compounds in which one or two of the methoxy or alkoxy groups attached to silicon are replaced by larger groups, e.g. 9-30C alkyl, aryl, 2-30C alkyl(poly)ether or triorganosilyl are new. Organosilicon compounds of formula (I) and/or (II) are new. R = methyl or ethyl; R' = 9-30C alkyl or alkenyl, aryl, aralkyl, 2-30C alkylether, 2-30C alkyl-polyether (all optionally branched) or R'''3Si; R'' = optionally unsaturated 1-30C aliphatic, aromatic or aliphatic/aromatic hydrocarbylene; R''' = 1-30C alkyl or alkenyl, aralkyl or aryl; X = NH3-n with n = 1, 2 or 3 and m = 1, or OCOR' with n = m = 1, or SH with n = m = 1, or S with n = 2 and m = 1-10, or SCOR' with n = m = 1, or H with n = m = 1. Independent claims are also included for: (1) a method for the production of (I) and (II) by reacting trialkoxysilyl compounds of formula ((RO)3Si-R)n-Xm (III) with alcohols R'-OH, with continuous removal of the resulting R-OH by distillation; and (2) rubber mixtures containing rubber, filler etc. and at least one compound (I) and/or (II).
