ABSTRACT:
Olefins having two and three carbon atoms are hydrated in the presence of phosphoric acid-containing supported catalysts to the corresponding alcohols. For the hydration of olefins having two carbon atoms, the molar ratio of water to olefin is in the range of about 0.1-0.3 : 1, the reaction temperatures in the range of about 190.degree.-230.degree.C, and the reaction pressure is in the range of about 60-80 atmospheres gauge. For the hydration of olefins having three carbon atoms, the molar ratio of water to olefin is in the range of about 0.1-0.3 : 1, the reaction temperatures in the range of about 140.degree.-170.degree.C and the reaction pressure is in the range of about 20-45 atmospheres gauge. The only by-products which form in addition to the raw alcohol under these conditions are steam-volatile (water soluble) by-products which are separated from the raw alcohol in a washing extraction zone. The by-products are recycled in aqueous solution without organic phase to the hydration in the state in which they are producted at the top of the washing extraction zone after separating unreacted olefin.
