Reaction Conditions:
Stage #1: tert-butylaminewith potassium sulfate;aluminum isopropoxide at 10; for 2 h;
Stage #2: with nickel(II) fluoride for 4 h;Temperature;Concentration;
Steps:
3 The method for synthesizing di-tert-butyl peroxide intermediate comprises the following steps
A: 2 mol of 2-methyl-2-propylamine was added to the reaction vessel.900ml mass fraction is 16% potassium sulfate solution, control stirring speed 130rpm, control solution temperature to 10 °C,Add 6 mol of aluminum isopropoxide,6 mol of a 25% diethylene glycol diethyl ether solution was added in 4 portions over a period of 50 min.Continue to react for 120 min;B: Then add 4 mol of nickel fluoride powder,Control the stirring speed at 250 rpm, continue the reaction for 4 h, and let stand for 50 min.The solution was layered and washed with a mass fraction of 21% sodium chloride solution for 40 min.It was washed with a mass fraction of 46% 1-pentanol solution for 40 min, and recrystallized in a mass fraction of 65% 2-hexanone solution.Anhydrous calcium sulfate dehydrating agent is dehydrated,The finished product was 286.744 g of di-tert-butyl peroxide, and the yield was 98.2%.
