HCID 16654(1,3-Phenylenebis(1-methylethylidene))bis(tert-butyl) peroxide

Procedure

1,3-Bis(2-t-butylperoxy-2-propyl)benzene (meta I) was prepared by reacting 29.7 grams (0.231 mole) of aqueous 70% t-butyl hydroperoxide with 20.4 grams (0.105 mole) of 1,3-bis(2-hydroxy-2-propyl)benzene in the presence of 26.8 grams (0.21 mole) of 77% sulfuric acid according to the procedure of Example I. The stripped product weighed 32.6 grams. It crystallized upon cooling and had a melting point of 45°-52° C. This example is for comparative purposes and does not fall under the specifications of this invention. The peroxide assay was 97% of theoretical.
