alpha-METHYLSTYRENE HYDROGENATION PROCESS |
| 摘要 |
FIELD: industrial organic synthesis. SUBSTANCE: alpha-methylstyrene contained in alpha-methylstyrene fraction formed in processing of cumene hydroperoxide cleavage products is hydrogenated at elevated temperatures and pressures on partially leached Cu-Zn-Al alloy in which Cu/Zn weight ratio is (2-10):1 and content of aluminum is 40-60%. EFFECT: increased catalytic activity and middle pressures in reaction zone. 3 cl, 2 tbl, 13 ex |
