94% | With 10H-phenothiazine;tetra-n-butylphosphonium chloride; at 108 - 112℃; under 75.0075 Torr; for 4h;Product distribution / selectivity; | A 500 ml flask with KPG stirrer, condenser and thermometer is initially charged with 319.12 g (1.50 mol) of <strong>[15267-95-5]chloromethyltriethoxysilane</strong>, and 8.85 g of tetrabutylphosphonium chloride and 0.15 g of phenothiazine are added. This charge is heated to 110 C. in an oil bath, and then 195.6 g (1.575 mol) of potassium methacrylate are added. At the end of the addition, the pressure in the reaction vessel is lowered to down to 100 mbar, and a total of around 15 g of low-boiling components are removed by distillation. Thereafter the pressure is raised again to atmospheric pressure. During the distillation, and also during the whole of the following reaction, the reaction temperature is held constant at between 108 and 112 C. After a total reaction time of 1 hour (including the distillation at the beginning of the reaction), the conversion to methacryloyloxymethyltriethoxysilane, determined by means of GC, is around 82 mol %. After 2 hours the conversion is around 92 mol %. After 4 hours the reaction is largely complete (i.e., the amount of unreacted <strong>[15267-95-5]chloromethyltriethoxysilane</strong> is less than 0.5 mol %). In all samples the ethanol content is between 1.2 and 1.5 mol %, with a slightly rising trend in the course of the reaction.After the filtration of the potassium chloride formed, the product is distilled using a laboratory short-path evaporator. This gives the product in a yield of around 94%, in a purity of around 98.5%. |
