Abstract
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.

In 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 an effective acid catalyst, the improvement comprising:
- (a) reacting said methanol with said branched monoolefin in the presence of a polymerization inhibiting amount of one or more diols to form a mixture comprising the methyl ether;
- and
- (b) separating said methyl ether from said diols by nonazeotropic distillation to provide methyl ether substantially free of said diols.
In 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 an effective catalyst, the improvement comprising the steps of:
- (a) reacting a branched monoolefin with an excess of one or more diols in the presence of an effective acid catalyst to form the corresponding monoether of said diols;
- (b) reacting said monoether with methanol in the presence of an effective acid catalyst to form a mixture comprising said methyl ether and said diols;
- and
- (c) separating said methyl ether from said mixture by nonazeotropic distillation to provide methyl ether substantially free of said diols or methanol and a residue substantially free of methanol.
