Preparation of Propylene Oxide

Abstract

The authors contemplated to find the most suitable conditions to manufacture propylene oxide via chlorohydrine process.
It was found that a high yield of propylene chlorohydrine is obtainable in circulating type reaction column.
Further investigations were made on the condition for direct utilization of untreated gaseous chlorine from electrolysis of salt water, and 95% yield has been achieved.
In manufacturing propylene oxide by the dehydrochloric acid of propylene chlorohydrine optimum conditions on holding time and were achieved when a horizontal type reactor having a providing net at the bottom was employed of the amount of direct blowing steam.
