Title:

METHOD FOR COEXISTING 1,2-DIFLUOROETHYLENE (HFO-1132) AND OXYGEN IN GAS PHASE, AND STORAGE CONTAINER AND REFRIGERATOR CONTAINING HFO-1132 AND OXYGEN

Document Type and Number:

WIPO Patent Application WO/2020/256129

Kind Code:

A1

Abstract:

The present invention addresses the problem of suppressing a polymerization reaction or an autolysis reaction of 1,2-difluoroethylene. To solve the problem, provided is a method for coexisting 1,2-difluoroethylene (HFO-1132) and oxygen in a gas phase, wherein the concentration of oxygen in the gas phase at a temperature of 25°C is at most 1,000 volume ppm.
