实验步骤: A 500 ml 5-neck round-bottom flask, rendered inert with nitrogen and equipped with paddle stirrer, dropping funnel, thermometer, and water separator with reflux condenser, is charged with 50 g (0.36 mol) of methyl-trimethoxysilane (available commercially from Wacker Chemie AG), 8.8 g (0.04 mol) of 3,3,3-trifluoro-propyltrimethoxysilane (available commercially from Fluka), and 39.7 g of Isopar E (isoparaffinic hydro-carbon mixture having a boiling range of 113-143° C., available commercially from ExxonMobil). The water separator is filled to the brim with Isopar E. Accompanied by stirring at 350 rpm, a solution of 17.2 g of potassium hydroxide (85% strength, available commercially from AppliChem) (0.26 mol of potassium hydroxide) and 15.3 g of demineralized water is metered in over 12 minutes. During this metered addition, the mixture heats up to 67° C. The mixture is heated to boiling temperature (70° C.). The distillate separates out as the bottom phase in the water separator. Up to a boiling temperature of 119° C., 48.5 g of colorless, slightly turbid distillate accumulate. The suspension which remains is subsequently evaporated to dryness with stirring under a full oil-pump vacuum (5 hPa) to 70° C. This gives 45.9 g of fine, white, free-flowable powder with a solids content of 99.7% (determined using the HR73 halogen moisture analyzer from Mettler Toledo at 160° C.). A 50% strength aqueous solution prepared with this powder exhibits no precipitation even after being stored at room temperature for two weeks in the absence of air.

实验步骤: Following the same general procedure described on Example 1, a flask was charged with one mol (218 gm) of 3,3,3-trifluoropropyltrimethoxysilane was added to one mol of 2-ethylpiperdinylmagnesium chloride, the salt having been prepared in situ by adding 2-ethylpiperidine (120 g, 1.05 mol) to isopropylmagnesium chloride (1 mol) in 500 ml of tetrahydrofuran. The reaction was mildly exothermic and the temperature rose to 45° C. at the end of the addition time of one hour. The reaction mixture was refluxed at the pot temperature of 70° C. for one hour and then cooled to room temperature. The 3,3,3-trifluoropropyl(2-ethylpiperidino)dimethoxysilane was filtered under nitrogen atmosphere from the magnesium methoxychloride. The filter cake was washed with ether (2×200 ml) to obtain the residual product. The solvent was removed by distillation to a pot temperature of 100° C. The residue was distilled under vacuum to yield 263 g of 3,3,3-trifluoropropyl(2-ethylpiperidino)dimethoxysilane as a colorless oil (purity>98%); bp 70° C./0.1 mm. The total yield was 88% of theoretical. the salt having been prepared in situ rose to 45° C. at the end of the addition time of one hour cooled to room temperature The 3,3,3-trifluoropropyl(2-ethylpiperidino)dimethoxysilane was filtered under nitrogen atmosphere from the magnesium methoxychloride The filter cake was washed with ether (2×200 ml) to obtain the residual product The solvent was removed by distillation to a pot temperature of 100° C The residue was distilled under vacuum
