    摘要: The reaction rate for the hydrolysis of carbonyl sulfide in liquid petroleum hydrocarbons over alumina, such as propylene, is greatly increased by maintaining water in the hydrocarbons in an amount of one mole of water per mole of carbonyl sulfide to an upper limit of about ten moles of water per mole of carbonyl sulfide or about 30% of saturation of the hydrocarbons, whichever upper limit provides the lesser amount of water.

    摘要: In a process for separating C⁴ to C⁷ tertiary mono-olefins(s) present in a C⁴ to C⁷ hydrocarbon mixture containing diolefins which comprises selectively reacting said tertiary mono-olefin mixture with a primary alcohol in the presence of an acid catalyst to convert it to tertiary ether(s). separating the tertiary ether(s) from the unreacted hydrocarbon mixture and containing said tertiary ether(s) in the presence of a catalyst to decompose it to tertiary olefin(s) and a primary alcohol. the improvement which comprises hydrogenating the tertiary ether(s) after it has been separated from the unreacted hydrocarbon mixture and prior to decomposition to saturate the unsaturated ether(s) formed from the diolefins present in the hydrocarbon mixture.
