PURIFICATION OF PROPYLENE OXIDE |
摘要 |
Methyl formate is removed from impure propylene oxide by contacting the impure propylene oxide in a treating zone with a basic ion exchange resin for a period of time sufficient to convert the methyl formate to formic acid and methanol, and by withdrawing a substantially methyl formate-free treated propylene oxide product from the treating zone. <IMAGE> |
