Yield:541-05-9 51.3% ,556-67-2 29.2% ,541-02-6 8%
Reaction Conditions:
with waterAutoclave;
Steps:
2-1
As a low dielectric liquid, 120 mL of cyclopentyl methyl ether was used as a reaction part. ESN 1 and ESN 2 made of stainless steel were immersed in the reaction part, and the distance between the opposing ESNs was 20 mm. 1 mL (8.30 mmol) of dichlorodimethylsilane as the first liquid sample (ESN 1 side), 0.15 m (8.32 mmol) of water as the second liquid sample (ESN 2 side), -4.0 kV to ESN 1, -4.0 kV to ESN 2 A high voltage of +4.0 kV was applied, the sample was electrostatically sprayed from ESN 1 at 0.02 mL / min and from ESN 2 at 0.003 mL / min to a high electric field in cyclopentyl methyl ether, and the reaction was confirmed and fused, . A conceptual diagram of the apparatus used in Example 2-1 is shown in FIG. After the reaction, the cyclopentyl methyl ether layer was analyzed by gas chromatography to find that the yield was 51.3% for hexamethylcyclotrisiloxane as a cyclic trimer and the yield of octamethylcyclotetrasiloxane as a cyclic tetramer was 29.2 %, Decamethylcyclopentasiloxane as a cyclic pentamer was produced in a yield of 8.0%.
