Examples
Embodiment 1
[0069] Take 1.62 parts of BYK-302 (polyether-modified polydimethylsiloxane), 6.49 parts of the compound shown in chemical formula 3-2; 20 parts of cyclohexanone; add it into a four-necked flask, and put Enter magneton, device condensation tube, thermometer; Connect nitrogen, 3 parts of sulfuric acid (60% concentration) are installed on the four-necked flask after packing into constant pressure dropping funnel, 80rpm stirring speed is connected in 70 degree water bath and reacted 2 hours, reduce Distill under pressure for 0.5 hours to remove by-products, lower the temperature to 50°C, and continue the reaction for 8 hours to end the reaction. Add 60 parts of n-hexane to precipitate the product, filter with Buchner funnel, and dry to obtain intermediate 4-1.
Embodiment 2
[0071] Get 3.24 parts of Ciba-EFKA-3883 (double-bond-terminated polyether modified silicone), and 1.26 parts of the compound represented by the above chemical formula 3-1 and 3.61 parts of the compound represented by 5-6; 20 parts of cyclohexanone; add four In the four-necked flask, put magnets in the four-necked flask, install a condenser, a thermometer, and communicate with nitrogen; 3 parts of aqueous nitric acid (1000ppm) are installed on the four-necked flask after being loaded into a constant pressure dropping funnel, and the stirring speed is connected to 240rpm. Put it in a water bath of 60 degrees to react for 2 hours, distill under reduced pressure for 0.5 hours to remove by-products, cool down to 50 degrees, continue to react for 8 hours, end the reaction, add 60 parts of n-hexane to precipitate the product, filter with Buchner funnel, and dry to obtain intermediate Body 4-2.
Embodiment 3
[0073] Take 1.62 parts each of Ciba-EFKA-3883 (double-bond-terminated polyether-modified silicone) and Ciba-EFKA-3034 (fluorocarbon-containing polyether-modified silicone), and 4.87 parts of the compound represented by the above chemical formula 3-2 20 parts of pimelinketone; add in the four-necked flask, and put into magneton in the four-necked flask, device condenser, thermometer, connect nitrogen, install after 3 parts of sulfuric acid (60% concentration) pack into constant pressure dropping funnel On the four-neck flask, 120rpm stirring speed was connected to a 60-degree water bath for 2 hours, and the by-products were removed by vacuum distillation for 0.5 hours. The temperature was lowered to 50 degrees, and the reaction was continued for 8 hours. The reaction was terminated, and 60 parts of n-hexane was added to precipitate the product. , filtered through a Buchner funnel, and dried to obtain intermediate 4-3.
