摘要： A SMALL AMOUNT OF IMPURITIES CONTAINED IN A SOLUTION OF A HIGH MOLECULAR WEIGHT SUBSTANCE HAVING A HIGH VISCOSITY IS DISSOLVED AND REMOVED BY CONTACTING SAID SOLUTION WITH AN EXTRACTING LIQUID OF A SOLUTION HAVING A LOW VISCOSITY BY USING A HORIZONTAL CYLINDRICAL TREATING VESSEL PROVIDED WITH TWO ROTARY DRIVING SHAFTS PARALLEL TO THE LONGITUDINAL DIRECTION OF SAID VESSEL WHICH ROTATE IN THE REVERSE DIRECTION WITH EACH OTHER EACH OF SAID DRIVING SHAFTS BEING PROVIDED WITH A PLURALITY OF ROTARY MEMBERS SO THAT THE ROTARY MEMBERS ON THE TWO DRIVING SHAFTS ARE OVERLAPPED AT A GIVEN DISTANCE WITHOUT CONTACTING WITH EACH OTHER AND A PARTITION WALL HAVING AN OPENING AROUND AND NEAR THE DRIVING SHAFT PROVIDED IN THE VICINITY OF THE LAST ROTARY MEMBER IN THE OUTLET SIDE OF THE HIGHLY VISCOUS SOLUTION. THE HIGHLY VISCOUS SOLUTION IS STIRRED WHILE BEING RETAINED BETWEEN THE ROTARY MEMBERS AND IMMERSED IN THE LOW VISCOUS SOLUTION AND ONLY THE HIGHLY VISCOUS SOLUTION TREATED WITH THE LOW VISCOUS SOLUTION IS DISCHARGED THROUGH THE OPENING OF THE PARTITION WALL.
