摘要： An improved process for the production of methyl ethers of the type in which methanol is reacted with a branched monoolefin in the presence of a catalytically effective amount of one or more acid catalyst, said improvements comprising carrying out said reaction in one or two steps in the presence of one or more liquid organic compounds having one or more hydroxy substituents which functions as a carrier for the branched monoolefins. The hydroxy compound also inhibits the polymerization of the branched monoolefins.

摘要： Methanol is reacted with branched monoolefins such as isobutylene, or mixtures of hydrocarbons such as mixed C-4's from or in a refinery, in the presence of methanesulfonic acid. A column (10) operation is described wherein methanesulfonic acid (11) and methanol (12) are fed in countercurrent fashion to hydrocarbons (13). Crude product ether is removed as a liquid sidestream (25) above the feed of methanesulfonic acid (11), while hydrocarbons depleted of the reactive branched monoolefins (24) are removed overhead. The methanesulfonic acid suppresses the vapor pressure of methanol relative to product ether.
