The present invention relates to a polymerization inhibitor of 1,3-butadiene and to 1,3-butadiene, comprising 4 tert-butyl catechol (TBC), diethyl hydroxylamine (DEHA) and an organic solvent. It relates to a polymerization prevention method.n n n The high-purity 1,3-butadiene product can be extracted and distilled by inhibiting the polymerization of 1,3-butadiene in a wide temperature range of gas and liquid state by the polymerization inhibitor having excellent polymerization inhibition to antifouling effect according to the present invention. It is possible to prevent emergency shutdown of the 1,3-butadiene manufacturing plant which may be caused by fouling, and to perform a safe operation for a long time.n n n n Polymerization inhibitors, 1,3-butadiene, diethyl hydroxylamine, isobutyl alcohol, isopropyl alcohol. |
