Title:
ＴＥＲＴ−ブチルヒドロペルオキシド溶液の製造及びそれから生成物を形成するための方法
Document Type and Number:
Japanese Patent JP6695005
Kind Code:
B2
Abstract:
A process for forming a concentrated solution, including distilling in a distillation zone comprised of 10 or more theoretical distillation stages, at a pressure of no greater than 300 mm Hg and a reflux ratio (D/L) of at least 1:1, an amount of an initial solution comprised of tert-butyl hydroperoxide (TBHP) in tert-butyl alcohol (TBA) having a TBHP concentration of up to 60 wt. % and a total impurity content greater than 0.01 wt. %, for a time and under distillation conditions to form a concentrated solution comprised of TBHP in TBA; and separating an overhead distillate from the distillation zone so that the concentrated solution thereafter has a TBHP concentration greater than 60 wt. %, a TBA concentration less than 40 wt. %, a water impurity content no greater than 0.1 wt. % and a total impurity content of no greater than 1 wt. %. Related epoxidation catalyst formation and epoxidation processes are also described.
