Polymerization inhibitor for tetrafluoroethylene |
| abstract |
The present invention provides a polymerization inhibitor preventing the self-polymerization of TFE and the generation of a modified polymer of a polymerization inhibitor in a distillation step, particularly in a rectification step, of TFE. The present invention provides a method of distilling tetrafluoroethylene in the presence of a polymerization inhibitor comprising a cyclohexadiene compound of the formula:n nR 1 -A-R 2 n nwherein R 1 is a hydrocarbon group having 1 to 5 carbon atoms, R 2 is a hydrogen atom or a hydrocarbon group having 1 to 5 carbon atoms, and A is a cyclohexadiene ring. The cyclohexadiene compound is preferably α-terpinene or γ-terpinene. |
