Embodiment 1
[0075] A preparation method of an anti-fingerprint agent, comprising:
[0076] Step 1: In a 5-liter high-pressure reactor equipped with a mechanical stirrer, under a nitrogen atmosphere, add 2000 mL of acetonitrile and 3310 g of compound B1 while stirring 83g of sodium dithionite and 21g of sodium bicarbonate were replaced with ethylene three times, then ethylene was introduced, heated to a temperature of 50°C, and reacted for 10 hours. 19FNMR followed the reaction. After the reaction, most of the solvent was evaporated under reduced pressure, and 2000 mL of water was added to the reaction system at a lower temperature, and the filtrate was obtained by filtration. The filtrate was extracted three times with 2000 mL of ethyl acetate, and the organic phase was extracted with 2000 mL of saturated sodium sulfite aqueous solution and 2000 mL of water respectively. Each wash once, after distilling off the extraction solvent, the water pump vacuum distillation obtains 1366g compound...
Embodiment 2
[0084] A preparation method of an anti-fingerprint agent, comprising:
[0085] Step 1: In a 5-liter high-pressure reactor equipped with a mechanical stirrer, under a nitrogen atmosphere, add 2500 mL of ethanol and 1235 g of compound B2 while stirring and 36g of benzoyl peroxide (BPO), replaced by ethylene three times, then passed through ethylene, heated to a temperature of 100°C, and reacted for 5h. After the reaction was completed, the filtrate was cooled and filtered to obtain the solvent. First, the solvent was removed by distillation under reduced pressure, and 1500 mL of dichloromethane was added. The organic phase was washed once with 2000 mL of saturated sodium sulfite aqueous solution, and then twice with 2000 mL of tap water. After the solvent was removed by distillation under reduced pressure, 1016 g of compound C2 was obtained. , whose structural formula is:
[0086] Step 2: 2000mL of ethylene glycol, 98.6g of magnesium chips, 1.0g of elemental iodine, heat and...
Embodiment 3
[0093] A preparation method of an anti-fingerprint agent, comprising:
[0094] Step 1: In a 5-liter high-pressure reactor equipped with a mechanical stirrer, under a nitrogen atmosphere, add 2000 mL of chloroform and 1650 g of compound B3 while stirring and 61g of benzoyl peroxide, replaced by ethylene three times, then passed into ethylene, heated to a temperature of 150°C, and reacted for 1h, using 19 F NMR followed the reaction. After the reaction, most of the solvent was evaporated under reduced pressure, and 2000mL of water was added to the reaction system at a lower temperature, and the filtrate was obtained by filtration. Each wash once, after distilling off the extraction solvent, the oil pump decompression distillation obtains 1450g compound C3, and its structural formula is:
[0095] Step 2: Fully stir and dissolve 2000mL ethylene glycol, 1500mL isopropyl ether and 545g potassium tert-butoxide, add toluene until there is no water in the system, then cool down to ...
