| titleOfInvention | Method for producing purified conjugated diene |
| abstract | In the manufacturing method of the refined conjugated diene which includes the process of isolate | separating a conjugated diene by extractive distillation from petroleum fraction containing a conjugated diene,n n n (1) using an amide compound as the extraction solvent;n n n (2) The extraction solvent adjusted to the presence of water in the range of 50 to 1,000 ppm based on the extraction solvent is supplied to the extraction distillation column.n n n (3) A method for producing purified conjugated diene, characterized in that extractive distillation of petroleum oil is carried out in the extractive distillation column. |
