FIELD: industrial organic synthesis.
SUBSTANCE: invention provides process for production of propylene oxide in presence of methanol, wherein propylene oxide is separated from propylene oxide/methanol mixture and methanol-containing raw mixture is then processed. Process is characterized by that, in the course of processing, methanol is separated from mixture containing methanol and methyl formate formed in the process.
EFFECT: enhanced process efficiency.
