Embodiment 1
[0052] A kind of epoxidized dicardanol carbonate toughening agent and preparation method thereof
[0053]Step 1): Dissolve 100 g of the compound of formula 1 in 500 mL of THF, add 46 g (1 eq) of potassium carbonate and 67 g (1 eq) of p-nitrophenoxychloroformate in 300 mL of THF, and react at 25 ° C for 5 h to obtain the intermediate formula 2 , this reaction system is reserved for future use.
[0054] Step 2): Add 100 g of the compound of formula 1 to the reaction system after the reaction in step 1), and react at 25°C for 8 hours. After the reaction is completed, filter the reaction system, remove the solvent under reduced pressure, add 500 mL of DCM to dissolve, and use 0.5M NaOH The aqueous solution was extracted twice, each time with 200 mL, the organic phase was washed, dried, and the solvent was removed under reduced pressure to obtain 183 g of the intermediate formula 3.
[0055] Step 3): Dissolve 100 g of the compound of formula 3 in 800 mL of DCM, add 100 mL of 30% h...
Embodiment 2
