| Application | used as an initiator for polyethylene, polyvinyl chloride, etc, is an efficient low-temperature initiator
used as a vinyl chloride monomer suspension polymerization initiator, can also be used as other monomer free radical polymerization initiator. |
| production method | the reaction of formic acid and isobutanol catalyzed by sulfuric acid to produce tert-valeric acid, the reaction is then carried out with phosphorus trichloride to produce tert-valeryl chloride. The latter reacts with tert-butyl hydroperoxide at 20 °c to form tert-butyl peroxyvalerate. Among them, tert-butyl hydroperoxide is prepared by the reaction of hydrogen peroxide and tert-butyl alcohol. Raw material consumption (kg/t) formic acid 1000 isobutyric acid 1250 tert-butanol 1400 hydrogen peroxide 9570 phosphorus trichloride 820 |
