Page/Page column 4, (2012/01/14)
The invention relates to a method for producing silanes (S) of the general formula (1); (R1)2C═C(R1)C(O)O—(R2)—Si(R3)z(OR4)3-z, starting from a alkyl halide silane (S1) of the general formula (2); X-(R2)-Si(R3)z(OR4)3-z, and a salt (S2) of an unsaturated organic carboxylic acid of the general formula (3); Mw+[(R1′)2C═C(R1)C(O)O?]w, where R1, R1′, R2, R3, R4, X, Mw+, w and z have the meanings given in claim 1, wherein one or more components (L) having a boiling point below the boiling point of the alkyl halide silane (S1) are at least partially removed from the reaction mixture, partial mixture or individual reactant components by distillation before or during the reaction of components (S1) and (S2).

Process for stabilizing organosilicon compounds (II) containing an unsaturated group of the vinyl, acrylic ester or vinyl ether type, during production, distillation and/or storage, comprises preparing (II) by reacting a haloalkylsilane with a salt of an unsaturated organic acid in the presence of alkylene-bis(dialkylphenol) compounds (I). Process for stabilizing organosilicon compounds of formula (II) containing an unsaturated group of the vinyl, acrylic ester or vinyl ether type, during production, distillation and/or storage, comprises preparing (II) by reacting a haloalkylsilane with a salt of an unsaturated organic acid in the presence of alkylene-bis(dialkylphenol) compounds of formula (I); [Image] H2C=C(R4>)[C(O)O]w(O)x-(R5>)y-Si(R6>)z(OR7>)3-z (II); R4>H or linear or branched 1-10 C hydrocarbyl; R5>linear, cyclic or branched 1-40 C hydrocarbyl, optionally containing heteroatom(s) selected from N, O, S or P; R6>, R7>linear, cyclic or branched 1-10 C hydrocarbyl; w, x : 0 or, in one case only, 1; y : 0 or 1; z : 0, 1 or 2; R1>, R2>linear or branched 1-20 C alkyl; R3>H or linear or branched 1-20 C alkyl.
