摘要: A process for the purification of olefine oxides by subjecting a mixture containing the olefine oxides to distillation in a distillation column in the presence of a small amount of water in order to obtain olefine oxide as the distillate. A fraction of the down-flow liquid is withdrawn from the column and the withdrawn fraction is subjected to decantation, so as to separate off an aqueous phase which is discarded, and an organic phase. The organic phase is returned to the column at a point located below the withdrawal point.

摘要: In apparatus for measuring out pulverulent materials, including a screw rotatably mounted in a barrel having an outlet at one end, the ability of the apparatus to impart a uniform flow rate to materials having poor flow properties is improved by interrupting the thread of the screw between any two circumferentially spaced generatrices of the cylindrical surface thereof and by disposing scraping elements to cooperate with the screw thread.
