Two-part room temperature condensation cure. Silicone can be formulated into two-part systems [3,12,14,33] that prevent the reactive groups from coming into contact before they are needed. The reactions in these systems are based on the condensation of a silanol group with an alkoxy silane group, catalyzed by organo-tin compounds (Scheme 9). [Pg.684]

Primare Phosphine werden durch Reduktion von Phosphonsaureestern (vier Hy-drid-Aquivalenten eines Organo-silans) oder aus Dihalogen-phosphinen (zwei Hy-drid-Aquivalenten) bei 150-200° erhalten, wobei das Phosphin unmittelbar aus dem An-satz herausdestilliert werden kann z.B. ... [Pg.485]

Sekundare Phosphine werden durch Reduktion von Phosphinsauren und deren Derivaten mit Organo-silanen (wie die primaren Phosphine) bzw. giinstiger mit Trichlor-silan erhalten. [Pg.485]

Tertiare Phosphin-oxide werden mit Organo-silanen oder Trichlor-silan (auch in Ge-genwart von Oxo-Gruppen erfolgt selektive Reduktion2) in ahnlicher Weise zu tertiaren Phosphinen reduziert. [Pg.485]

Organo-silane werden durch Elektrolyse an der C-Metall-Bindung gespalten. So erhalt man z. B. aus Trimethyl-phenylathinyl-silan in Methylamin/Lithiumchlorid (s. a. S. 577) an Platin-Elektroden Phenyl-acetylen (38% d.Th.). Als Nebenprodukte fallen infolge Hydrierung Trimethyl-(2-phenyl-athyl)-silan (10% d.Th.) und A thy T benzol (30% d.Th.)... [Pg.638]

Multifunctional (meth)acrylate alkoxysilanes were developed, a new class of reactive compounds. Compared with commercially available organo(alkoxy)silanes having reactive C=C bonds in the organic substituent, the new compounds can be varied to a much higher degree. The main improvements are ... [Pg.301]

Schneider and Brebner (1985) impregnated wood samples with the organo-silane y-methacryloxypropyltrimethoxysilane (TMPS) (Figure 7.9a) and determined the dimensional stability as a resnlt of this treatment. Wood samples were conditioned to 6-8 % MC before being impregnated with a methanolic solution of the silane. The methanol was allowed to evaporate from the treated samples and they were then submerged in water to... [Pg.167]
