Abstract
The authors contemplated to find optimum conditions to manufacture propylene oxide and glycol by pilot plant.
In manufacturing propylene chlorohydrin in circulating type column it was found that over 95% yield was achieved in continuous reaction, and that the formation of dichloride was from four to six times much as in batch reaction, and it was also recognized that the reaction temperature was kept almost constant without any cooling in continuous reaction.
In manufacturing propylene oxide in the reactor having a providing net at the bottom it was found that the increase in pressure of the reactor owing to the connection to a distillation tower caused the yield worse, and the relation between the composition and the temperature in the distillation tower was also studied.
Further investigations were made for the optimum condition in manufacturing propylene glycol using a multiple-type continuous reactor.
