Embodiment 1
[0100] 500 g of the triazine-aryl hydroxy-aldehyde condensate formed from the comparative example and 50% potassium hydroxide in methanol were charged to a tank equipped with mechanical stirrer, reflux condenser, thermocouple and thermocouple control 2 L pressure reactor with heating jacket. The reactor was flushed with nitrogen to remove air and heated to 90°C, followed by vacuum dehydration at 120°C to remove traces of water and methanol. The mixture is then heated to a temperature of 150-160°C. Then, 20% of 1015 g of ethylene oxide was then charged to the flask to initiate the reaction, followed by the rest of the ethylene oxide to 4.0 kg / cm 2 pressure. Make the reaction mixture at 165°C at 4.0kg / cm 2 The reaction was then cooled to 70-75°C and neutralized to pH 7-8. The yield is 87%.
Embodiment 2
[0102] 500 g of the triazine-aryl hydroxy-aldehyde condensate formed from the comparative example and 50% potassium hydroxide in methanol were charged to a tank equipped with mechanical stirrer, reflux condenser, thermocouple and thermocouple control 3 L pressure reactor with heating jacket. The reactor was flushed with nitrogen to remove air and heated to 90°C, followed by vacuum dehydration at 120°C to remove traces of water and methanol. The mixture is then heated to a temperature of 150-160°C. Then, 20% of 3254 g of ethylene oxide was then charged to the flask to initiate the reaction, followed by the rest of the ethylene oxide to 4.0 kg / cm 2 pressure. Make the reaction mixture at 165°C at 4.0kg / cm 2 The reaction was then cooled to 70-75°C and neutralized to pH 7-8. The yield is 85%.
Embodiment 3
[0104] 135 g of the triazine-aryl hydroxy-aldehyde condensate formed from the comparative example and 50% potassium hydroxide in methanol were charged to a tank equipped with mechanical stirrer, reflux condenser, thermocouple and thermocouple control 2 L pressure reactor with heating jacket. The reactor was flushed with nitrogen to remove air and heated to 90°C, followed by vacuum dehydration at 120°C to remove traces of water and methanol. The mixture is then heated to a temperature of 150-160°C. Then, 20% of 1370 g of ethylene oxide was then charged to the flask to initiate the reaction, followed by the rest of the ethylene oxide to 4.0 kg / cm 2 pressure. Make the reaction mixture at 165°C at 4.0kg / cm 2 The reaction was then cooled to 70-75°C and neutralized to pH 7-8. The yield is 92%.
