tert-Butyl hydroperoxide → Tert-butylperoxy propan-2-yl carbonate

Participants

Reaction Steps

129 parts (1 mol) of TBHP-70, 92 parts of water and 172 parts of LUP were fed into a 1-l glass beaker. 170 parts (1 mol) of 25% aqueous caustic soda was added dropwise to the beaker over a period of 20 minutes while keeping the contents at 25° C. on an ice-water bath. After the completion of the dropwise addition, the temperature of the contents was lowered to 10° C., followed by the dropwise addition thereto of 126 parts (1 mol) of isopropyl chloroformate over a period of 50 minutes. The obtained mixture was stirred for 50 minutes. 250 parts of 5% aqueous caustic soda was added to the formed organic layer to transfer unreacted materials from the organic layer to the aqueous layer. The resulting organic layer was thrice washed with 250 parts of water and dehydrated with a dehydrating agent to obtain 334 parts of t-butylperoxy isopropyl carbonate diluted with LUP to 50% (hereinafter abbreviated to "TBIC-LUP 50") as a final product.
