Purification of propylene oxide by treatment with a selected base and inert salt

摘要

Methyl formate is removed from propylene oxide by treatment with a selected base such as sodium hydroxide in water and glycerol. Selected inert salts may be added. The rate of methyl formate hydrolysis by selected bases was increased to commercially acceptable levels by addition of the glycerol. The glycerol and inert salts reduced the amount of residual water in the propylene oxide.
