Yield:614-45-9 98.3%

Reaction Conditions:

Stage #1: tert-butyl alcoholwith sodium hydroxide at 15 - 20; for 1 h;
Stage #2: benzoyl chloride at 10 - 15; for 1.5 h;Temperature;

Steps:

1-5 Example 3: Preparation of tert-butyl peroxybenzoate

Add 72g of 10% sodium hydroxide (0.18mol) solution into the reaction flask, lower the temperature to 15-20°C, slowly add 23.2g (0.16mol) 70% tert-butanol dropwise, and the reaction is complete. 1 hour; keep the temperature at 10-15 and add 24.7g (0.176mol) benzoyl chloride dropwise, after the dropwise addition, keep warm and stir for 1 hour; let stand for 0.5 hours and then separate, the lower layer of high-salt wastewater is collected for three-effect evaporation treatment, the upper layer The organic phase was stirred and washed twice with 30ml/time purified water, and then the lower layer was separated into 0.2g stabilizer and 1g anhydrous magnesium sulfate, dried, and filtered with suction to obtain 99.08% tert-butyl peroxybenzoate 30.4 g, the yield is 98.3%.
