Versuchsvorschrift

129 parts (1 mol) of t-butyl hydroperoxide diluted with water to about 70% (TBHP-70) and 100 parts of water were fed into a 1-1 glass beaker, followed by the addition of 182 parts of LUP. 160 parts (1 mol) of caustic soda diluted with water to 25% was added dropwise thereto, while keeping the contents at 20° C. on an ice-water bath. After the completion of the dropwise addition, 140 parts (1 mol) of benzoyl chloride was added dropwise thereto over a period of 30 minutes. The contents were stirred for 60 minutes, while keeping them at 20° C. 250 parts of 5% aqueous caustic soda was added to the formed organic layer. The obtained mixture was stirred for 30 minutes to transfer unreacted materials to the aqueous layer from the organic layer. The resulting organic layer was thrice washed with water and dehydrated with a dehydrating agent to obtain 364 parts of t-butylperoxy benzoate diluted with LUP to 50% (hereinafter abbreviated to "TBPB-LUP 50") as a final product.
