Route of Synthesis (ROS)
Route of Synthesis (ROS) of Tris(dimethylamino)silane CAS 15112-89-7
| Conditions | Yield |
| With trichlorosilane; magnesium In ethylene glycol dimethyl ether; n-heptane at 85℃; for 10.5h; Solvent; Temperature; Experimental Procedure Into a 3 L four-neck flask, 87.5 g (3.6 mol) of magnesium and 750 g of n-heptane were charged. An oil bath was heated to 115° C., while stirring the resulting mixture, into a reflux state for 1 hour, and moisture in a solvent and an apparatus was allowed to react with magnesium to dehydrate the solvent and the apparatus, and then the resulting content was cooled with ice water. Into a 500 mL feed tank, a mixture (468 mL) of 408 g (3.01 mol) of TCS and 150 g of DME was charged, and when an internal temperature was decreased to 5° C., 30 mL of a mixture of TCS and DME was charged into the 3 L four-neck flask. In a state in which the temperature was maintained at 10° C. or lower, DMA was fed from a gas phase part of the flask thereinto at a rate of 240 mL per minute for 1 hour.First Reaction Step The oil bath was set to 90° C., and heated until a temperature of a reaction liquid reached 85° C. On the way of the heating, a reaction between DMA hydrochloride and magnesium occurred, but no noticeable rapid increase in temperature was observed. When an internal temperature was maintained at 85° C., TCS was added dropwise into the liquid at a rate of 55 mL per hour, and simultaneously feed of DMA to a gas phase was started at a rate of 420 mL per minute. A time of simultaneous feed of DMA was 8 hours, and a GC analysis of the reaction liquid at completion of the simultaneous feed resulted in 9.3% of DME, 63.0% of n-heptane and a 1D form, 14.8% of a 2D form and 12.9% of TDMAS.Second Reaction Step Further, DMA was fed for 2 hours and 30 minutes. Then, 555 g (12.3 mol) of DMA in total was fed. When reduction of the temperature of the reaction liquid and loss of the 2D form of an intermediate product by the GC analysis were confirmed, feed of DMA was stopped. After cooling, 1950 g of the reaction liquid was obtained.Posttreatment Step The reaction liquid was filtered by a pressure filter, and a residue was washed with 300 g of n-heptane to obtain 1434 g of a filtrate containing TDMAS. When the GC analysis was conducted, 464 g (2.87 mol) of TDMAS was contained therein and a reaction yield was 95%. | 95% |
