Ethene and steam reaction conditions
WebIn this process ethene and steam (water in the gaseous phase) are passed at 300°C and a pressure approximately 60 times above atmospheric pressure over a phosphoric acid catalyst to produce ethanol. This reaction is reversible with only 5% of the ethene converting to ethanol with each pass over the catalyst in the reactor. WebEthene at atmospheric concentrations up to 20% was not mutagenic to one strain of Salmonella typhimurium with and without liver metabolic activation system (S9). In other …
