Abstract
(a) A medium oil wherein a main component is a hydrocarbon, and the number of paraffinic carbon atoms is 70% or more with respect to a total number of carbon atoms, (b) a medium oil wherein a main component is a polybutene, (c) a medium oil wherein a main component is a mixture of hydrocarbons of the formula (1):CH3—C(CH3)2—[—CH2—C(CH3)2—]n—CH2—R (1)wherein R is —CH(CH3)2 or —C(CH3)═CH2, and n is 1 to 10, (d) a medium oil wherein a main component is a hydrocarbon prepared by a Fischer-Tropsch synthesis, or (e) a medium oil wherein a main component is a branched paraffinic hydrocarbon prepared by hydrogenolysis of a hydrocarbon prepared by a Fischer-Tropsch synthesis, and a process of producing dimethyl ether using the medium oil, are disclosed.
