Patent ID: 6841694

Claim:
A process for stabilizing organosilicon compounds bearing unsaturated groups of the formula II: H 2 C═C(R 4 )[C(O)O] w (O) x —(R 5 ) y —Si(R 6 ) z (OR 7 ) 3-z II during one or more of their preparation, distillation, or storage; wherein R 4 is a hydrogen atom or a linear or branched hydrocarbon radical having 1-10 carbon atoms; R 5 is a linear, cyclic or branched hydrocarbon radical having 1-40 carbon atoms optionally containing one or more heteroatoms selected from the group consisting of nitrogen, oxygen, sulfur and phosphorus; R 6 and R 7 are independently linear, cyclic, or branched hydrocarbon radicals having 1-10 carbon atoms, wherein w is 0 or 1, x is 0 or 1, y is 0 or 1, and z is 0, 1 or 2, and wherein w and x are not both 1 simultaneously, the compounds of the formula II having been obtained by reacting a haloalkylsilane with a salt of an unsaturated organic acid, by adding an effective stabilizing amount of one or more compounds of the formula I: wherein R 1 and R 2 are identical or different linear or branched alkyl radicals having 1-20 carbon atoms and the radicals R 3 are identical or different substituents selected from the groups consisting of hydrogen and linear and branched alkyl radicals having 1-20 carbon atoms.
