2- ethylene halohydrin 6~14h is reacted at 60 DEG C~100 DEG C；Or make two bromo-silicane of dimethyl and three of molar ratio 3: 1
(2- ethoxy) isocyanuric acid ester in organic solvent at 40 DEG C~70 DEG C react 4~7h, then with relative to three (2- hydroxyl second
Base) 3~4 times moles of isocyanuric acid ester of 2- ethylene halohydrin reacts 6~12h at 40 DEG C~100 DEG C；Purified processing must be matched
Gram dimethyl Chloroethoxy esters of silicon acis.
Further, this method specifically:
Under conditions of nitrogen protection, three (2- ethoxy) isocyanuric acid esters are dissolved in volume ml relative to three (2-
Ethoxy) isocyanuric acid ester 10~15 times of quality grams of organic solvent in, 30 DEG C or less be added relative to three (2- hydroxyl second
Base) 3 times moles of isocyanuric acid ester of dimethyldichlorosilane, 50 DEG C~70 DEG C are warming up to, 5~9h of insulation reaction；It is discharged to HCl
Afterwards, 30 DEG C are cooled to hereinafter, the 2- ethylene halohydrin relative to 3~4 times moles of isocyanuric acid ester of three (2- ethoxy) is added dropwise, with drop
Acceleration Control reaction temperature is not higher than 40 DEG C, 60 DEG C~100 DEG C is warming up to after dripping off, 6~14h of insulation reaction；Purified place
Reason, get Sai Ke dimethyl halo ethyoxyl esters of silicon acis.
This method may be used also are as follows:
Under conditions of nitrogen protection, three (2- ethoxy) isocyanuric acid esters are dissolved in volume ml relative to three (2-
Ethoxy) isocyanuric acid ester 10~15 times of quality grams of organic solvent in, 30 DEG C or less be added relative to three (2- hydroxyl second
Base) 3 times moles of isocyanuric acid ester of two bromo-silicane of dimethyl, 40 DEG C~70 DEG C are warming up to, 4~7h of insulation reaction；It is discharged to HBr
