Nomination Background: Cumene (CASRN: 98-82-8)
WebFor the recovery of cumene from phenol by distillation, knowledge on vapor–liquid equilibrium (VLE) behavior is important, in combination with how this is affected by other components possibly present as an impurity or explicitly added as a solvent. This was investigated in this work. RESULTS WebOptionally, the cumene recovery column can be operated to recover alpha-methylstyrene (AMS) with the cumene. If the AMS is not recovered with the cumene, the product … WebMar 24, 2024 · The main process for producing cumene is a synthetic route where benzene is alkylated with propylene to isopropylbenzene. Either a liquid or a gas-phase process is used for the alkylation reaction. In the liquid-phase process, low temperatures and pressures (approximately 50°C and 5 atmospheres ) are used with sulfuric acid as a catalyst. jet two holidays manage my booking
