Synthesis of 1,2-butadiene |
| abstract |
SIGNIFICANT QUANTITIES OF 1,2-BUTADIENE ARE PRODUCED FROM A 2-BUTYNE FEED STREAM BY PLACING THE FEED STREAM IN CONTACT WITH A BASE-TREATED CATALYST COMPRISING SILICA OR ALUMINA FOR FROM 1.0 TO 100 SECONDS AT A TEMPERATURE OF FROM ABOUT 200* C. TO ABOUT 600* C., AND RECOVERING THE DESIRED 1,2-BUTADIENE FROM THE PRODUCTS THUS FORMED. |
