In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 2062-98-8, name is Perfluoro(2-methyl-3-oxahexanoyl) fluoride belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. COA of Formula: C6F12O2
In a four-necked flask equipped with a stirrer, a thermometer, a dropping funnel, and a reflux condenser (anhydrous calcium chloride at the top),Add 1,3-dimethyl-1,3,5-triazine (2.76 g, 24 mmol)And dichloromethane (30 mL),After stirring to dissolve, add triethylamine (3.25mL, 26mmol) and cool to 0 C.Was added dropwise with stirring hexafluoropropylene oxide dimer (6.64g, 20mmol),After 1 hour, the addition was completed. After the addition, the reaction was stirred at 0 C for 3 hours.The reaction mixture was washed with 10% sodium hydroxide solution (50 mL) and separated. The organic layer was washed with water, dried over anhydrous sodium sulfate, and the solvent was spin-dried.The residue was separated and purified by column chromatography [dichloromethane / methanol (v / v) = 20/1],7.86 g of a colorless transparent liquid fluorinated intermediate I-1 were obtained,Yield: 92%.
The synthetic route of 2062-98-8 has been constantly updated, and we look forward to future research findings.
