Abstract

The hydration of ethylene and propylene is effected by absorbing ethylene substantially free from higher olefines in a highly concentrated acid, such as sulphuric or phosphoric acid, diluting the absorption liquor, absorbing propylene in the diluted liquor and finally recovering the oxygen - containing products. The absorption may be facilitated by the addition of a catalyst, such as silver or silver and copper compounds, and the absorption of ethylene is preferably stopped when about 0.8 molecule of ethylene per molecule of acid has been absorbed, and, using sulphuric acid of 92-98 per cent, water may be added equal to 7-10 per cent of the liquor for the absorption of propylene. The ethylene for the first treatment may be obtained from cracking gases by washing with liquid hydrocarbon to remove higher olefines, and the gas recovered from the liquid hydrocarbon may be used as the source of propylene, residual gas being used as ethylene.
