Reaction Conditions:

Stage #1:isopropyl chloride with iodine;magnesium in diethyl ether at 15; for 5 h;Inert atmosphere;
Stage #2:chloromethyltriethoxysilane in diethyl ether at 30; for 2 h;Inert atmosphere;Reagent/catalyst;Solvent;Temperature;

Steps:

3
In a three-necked flask, 0.1 mol of magnesium dust, 0.2 mol of 2-chloropropane, 0.2 mol of diethyl ether and 1 part of iodine were added to the three-necked flask, and the reaction was stirred for 5 hours under the protection of nitrogen at a water bath temperature of 15 ° C.The product obtained in step 1 is filtered and the filtrate is added dropwise to 0.2 mol of chloromethyltriethoxysilane and stirred at 30 ° C for 2 h to obtain crude isobutyltriethoxysilane.The crude product was subjected to vacuum distillation under reduced pressure at a negative pressure of 3 kPa, and a distillate fraction at a temperature of 68 to 71C was collected to obtain a high purity isobutyltriethoxysilane product.The yield was 93%.The product was qualitatively analyzed by gas chromatography-mass spectrometry. The purity of the product was measured by gas chromatography. The inorganic chloride ion content of the product was determined by titration. The purity of the product was 99.5%, the content of inorganic chloride was less than 50 ppm at 25 ° C and 0.88 g / cm³at25 ° C
