| production method | is obtained by reacting isopropyl chloroformate with sodium peroxide. First, the sodium hydroxide solution was added into a glass-lined reaction pan, and hydrogen peroxide was added dropwise thereto, and the temperature was maintained at about 10 ° C. To obtain a sodium peroxide solution. The solution was slowly dropped into isopropyl chloroformate and the temperature was strictly controlled at 10±2 °c to prevent explosion. After completion of the addition, stirring was continued until the end of the reaction. The layers were allowed to stand, the upper layer was milky white IPP, and the lower layer was the mother liquor containing alkali impurities. The lower layer was discharged, and the contents of the pot were washed with cold water stirring at 12 ° C., and the layers were allowed to stand, with water in the upper layer and IPP in the lower layer. Release IPP, add xylene diluted to 55-60% concentration, refrigerated at -4 ℃ for standby. Kg/ton of isopropyl chloroformate 1620 hydrogen peroxide 660 isopropyl chloroformate ([108-23-6]) can be obtained by phosgenation of isopropanol. Isopropyl alcohol and sodium hydroxide solution were added into a glass-lined reaction pot, and phosgene was passed through at 40 ° C. For 5-7 hours to obtain a transparent liquid of isopropyl chloroformate, which was washed with water and then stored at low temperature. From the reaction of chloroformate isopropyl Ester and sodium peroxide: first, sodium hydroxide solution is added into the enamel glass reaction pot, and hydrogen peroxide is added dropwise, and the temperature is maintained at about 10 ° C., to obtain sodium peroxide solution. The solution was slowly dropped into isopropyl chloroformate and the temperature was strictly controlled at (10±2) °c to prevent explosion. After completion of the addition, stirring was continued until the end of the reaction. The layers were allowed to stand, the upper layer was milky white IPP, and the lower layer was the mother liquor containing alkali impurities. The lower layer was discharged, and the contents of the pot were washed with cold water stirring at 12 ° C., and the layers were allowed to stand, with water in the upper layer and IPP in the lower layer. Release IPP, add xylene to dilute to 55% ~ 60%, refrigerated at -4 ℃ for standby. Attachment: preparation of isopropyl chloroformate isopropyl chloroformate (C4H7ClO2,[108-23-6]) can be added into enamel glass reaction pot by isopropyl alcohol and sodium hydroxide solution, at 40 ℃ through 5~7H, A transparent liquid of isopropyl chloroformate was obtained, which was washed with water and then stored at low temperature. |
