Embodiment 1
[0021] In a 500ml four-neck flask equipped with a thermometer, a stirrer, a nitrogen inlet tube, and a distillation head, add 150g (0.155mol) of nonylphenol polyoxyethylene ether (17) (NP-17), 64.2g (0.170mol) of ethanol Sodium ethanol solution (18%), heated up to 120°C-140°C under stirring, controlled the reaction temperature to be 130°C-135°C, continuously distilled low boiler ethanol out, reacted for 16 hours, in N 2 Cool slowly to room temperature under protection. Remove the distillation device, add 35.8g (0.170mol) of chloropropylmethyldiethoxysilane, stopper the mouth of the bottle with a glass stopper, then raise the temperature to 100°C-120°C under stirring, react for 10 hours, and cool to room temperature. Add 310g of anhydrous toluene, stir to dissolve, and filter to remove insoluble matter. Toluene and excess chloropropylmethyldiethoxysilane were distilled off under reduced pressure to obtain 178 g of viscous yellow-brown liquid (NP-17-diethyl). The product is d...
Embodiment 2
[0023] In a 500ml four-neck flask equipped with a thermometer, a stirrer, a nitrogen inlet tube, and a distillation head, add 140g (0.145mol) of nonylphenol polyoxyethylene ether (17) (NP-17), 60.1g (0.159mol) of ethanol Sodium ethanol solution (18%), heated up to 120°C-140°C under stirring, controlled the reaction temperature to be 130°C-135°C, continuously distilled low boiler ethanol out, reacted for 16 hours, in N 2 Cool slowly to room temperature under protection. Remove the distillation device, add 38.2g (0.159mol) chloropropyltriethoxysilane, stopper the bottle mouth with a glass bottle stopper, then raise the temperature to 100°C-120°C under stirring, react for 10 hours, and cool to room temperature. Add 300g of anhydrous toluene, stir to dissolve, and filter to remove insoluble matter. Toluene and excess chloropropylmethyldiethoxysilane were distilled off under reduced pressure to obtain 170 g of viscous yellow-brown liquid (NP-17-triethyl). The product is determine...
Embodiment 3
[0025] In a 500ml four-neck flask equipped with a thermometer, a stirrer, a nitrogen inlet tube, and a distillation head, add 160g (0.165mol) of nonylphenol polyoxyethylene ether (17) (NP-17), and 19g (0.182mol) of hydroxide Sodium solution (38.4%), heated up to 120°C-140°C under stirring, controlled the reaction temperature to be 130°C-135°C, continuously distilled low boiler ethanol out, reacted for 18 hours, and 2 Cool slowly to room temperature under protection. Remove the distillation device, add 33.2g (0.182mol) chloropropylmethyldimethoxysilane, stopper the bottle mouth with a glass bottle stopper, then raise the temperature to 100°C-120°C under stirring, react for 11 hours, and cool to room temperature. Add 330g of anhydrous toluene, stir to dissolve, and filter to remove insoluble matter. Toluene and excess chloropropylmethyldimethoxysilane were distilled off under reduced pressure to obtain 184 g of viscous yellow-brown liquid (NP-17-trimethyl). The product is det...
