Trimethoxysilane → A-Link 15

Temperature

88 °C

To a 500 gallon reactor were added 489 kg (4.94 kmols) of N-ethylmethallylamine and 1425 g of platinum catalyst. The resulting solution was heated to 88° C. and 725 kg (5.94 kmols) of trimethoxysilane were added at such a rate to keep the temperature under 105° C. After addition was complete, the contents were heated to 110° C. for one hr. The low boiling byproducts were then removed by overhead stripping. The mixture was then cooled and approximately 60 L of methanol were added, and the reaction mixture was agitated at 50° C. for 1 hour before stripping the excess methanol. The resulting crude material (>97% purity) was then transferred from the reactor. The process was repeated without cleanup of the reactor to yield a combined total of 1638 kg (7.41 kmol) of N-ethyl-3-trimethoxysilyl-2-methylpropanamine.
