A catalytic process is provided for the manufacture of ethers by reacting a linear monoolefin with a primary or secondary alcohol having up to 4 carbon atoms. The process selectively forms methyl isopropyl ether from a propylene feed and methanol by contact with a zeolite such as Zeolite Beta or ZSM

A catalytic process is provided for the manufacture of ethers by reacting a linear monoolefin with a primary or secondary alcohol having up to 4 carbon atoms. The process selectively forms methyl isopropyl ether from a propylene feed and methanol by contact with a zeolite such as Zeolite Beta or ZSM-5, or by contact with a macroreticular sulfonated ion-exchange resin.

A process for the manufacture of methyl isopropyl ether from methanol and a C3 hydrocarbon fraction that contains about 20 to 100 wt % of propylene, which process comprises: preparing a mixture of said hydrocarbon fraction and 0.1 to 10 mols of methanol per mol of propylene contained in said fractio

A process for the manufacture of methyl isopropyl ether from methanol and a C3 hydrocarbon fraction that contains about 20 to 100 wt % of propylene, which process comprises: preparing a mixture of said hydrocarbon fraction and 0.1 to 10 mols of methanol per mol of propylene contained in said fraction, contacting said mixture with a solid insoluble acidic catalyst comprising materials having the structure of Zeolite Beta, said contacting being effected under a combination of conditions effective to selectively form said ether, said conditions including 1.0 to 300 atmospheres pressure, a temperature of 50°C. to about 300°C., and a WHSV of 0.5 to 50, and recovering from said contacted mixture a fraction comprising methyl isopropyl ether.
