Steps:

18 Synthesis of bis(1,1-dimethylpropyl)peroxide (Peroximon S 172) of formula:

Example 18 Synthesis of bis(1,1-dimethylpropyl)peroxide (Peroximon S 172) of formula: A 1 l 4-necked flask equipped with stirrer, thermometer and efficient cooler was charged with 400 g of 2-methyl-2-butanol (4.54 moles). After having brought the temperature to 40°C, 115.8 g of H₂O₂ at 70% (2.383 moles) and 453.4 g of H₂SO₄ at 70% (3.236 moles) were simultaneously introduced over 60 minutes. The reaction was stopped after 6 hours by discontinuing the stirring. After separation, 318.4 g of crude product were obtained (86.5% iodometric titre as peroxide), which was then purified by repeated washings with equal portions of NaOH at 10%. The washed product was then purified by means of rectification under vacuum, thereby obtaining 250 g of product at 99.5% of gas-chromatographic titre.
