    摘要: Methyl t-butyl ether and methyl t-amyl ether are produced by reacting methanol with isobutene and isoamylene, respectively, at a total methanol/isoolefine mole ratio of 1-1.2:1 in a series of reaction stages such that in the first reaction stage, the total amount of olefin component is reacted with as much methanol as is required to ensure that the methanol/isoolefine mole ratio in the first reaction stage does not drop to less than 0.65:1, and that the methanol concentration in the effluent stream does not exceed 0.4% wt. The residual amount of methanol is then fed either all at once to another reaction stage, or in portions to several additional reaction stages.
