Global ethylene oversupply scenario not as bad, according to analyst of India Equity Research. New capacities in the Middle East 19 Mt/y in operation/next to start operation, 12 Mt/y capacity on hold!
Ethylene oxide is an alkylating agent and a model direct-acting mutagen and carcinogen, OSHA limit: 1 ppm TWA, IARC: probable human mutagen and carcinogen. Non-occupational level: 0.55 mg/cigarette. Manufacture: selective oxidation of ethylene over silver catalyst @180-240°C, 2.1 Mpa in fixed bed reactor: C2H4+0.5O2C2H4O DH298=-105.39 kJ/mol C2H4+3O22CO2+2H2O DH298=-132173 kJ/mol
Colloid chemistry intermission, role of ETO in controlling HLB (Hydrophilic-lipophilic balance):
Ethanol amines (MEA,DEA,TEA) made by ethylene oxide reaction with aqueous ammonia
Ethylene oxide based Transition metal catalyst
