| titleOfInvention | Manufacturing procedure for organosilicon products with improved quality using heterogeneous precious metal catalysts |
| abstract | Procedure for the manufacture of an organosilicon product that has a stabilized low color and without formation of black particles during storage, the process comprising the steps of: a) reacting an unsaturated compound with a silicon compound having a Si-bond. H reactive under hydrosilylation conditions in a reaction zone in the presence of a heterogeneous precious metal catalyst to provide an organosilicon product having a color of less than 40 pt / c according to ASTM D 1209, in which the compound of Silicon is a siloxane having the formula: (M) a (M!) b (D) c (D!) D (M) e (M!) f in which M = (R3) (R4) (R5) SiO1 / 2, M! = (R6) (R7) HSiO1 / 2, D = (R8) (R9) SiO2 / 2 D! = (R10) HSiO2 / 2 and R3, R4, R5, R6, R7, R8, R9 and R10 can be the same or different alkyl or alkoxy groups having from 1 to 5 carbon atoms, a = 0 or 1, b = 0 or 1, provided that a + b = 1, c = from 0 to 100, d = from 0 to 100, provided that c + d is at least 1, e = 0 or 1, and f = 0 or 1, always that e + f = 1; wherein the unsaturated compound is selected from the group consisting of 1-octene, polyoxyalkylene having the formula R11 (OCH2CH2) m (OCH2CH (CH3)) n OR12 where R11 is an unsaturated organic group containing from 2 to 10 carbon items, R12 is hydrogen or polyether protection groups, m = 0 to 100, and n = 0 to 100, provided that m + n is at least 1; eugenol, allyl glycidyl ether, allyl methacrylate, vinylcyclohexene monoxide, styrene, alpha-methylstyrene, allylamine, acrylonitrile, and allyl chloride, and in which the precious metal catalyst comprises a noble metal selected from the group consisting of Pt, Pd, Rh, Ru, Ir and Os charged on an organic polymeric support or an inorganic support selected from the group consisting of activated carbon, functionalized or non-functionalized silica, alumina and zeolite; b) separating the heterogeneous precious metal catalyst from the organosilicon product; and c) recovering the heterogeneous precious metal catalyst, wherein the organosilicon product is a component in at least one of a personal care composition, an agricultural composition, a home care composition, a polyurethane foam composition, or a plastic additive composition and in which steps (b) and (c) are performed without the use of distillation or devolatilization. |
