A process for alkylating an isoparaffin comprising reacting an isoparaffin with a monoolefin in the presence of a salt of a heteropoly-acid as a solid catalyst. The salt of the heteropoly-acid is a compound obtained by substituting a cation for a hydrogen ion of a heteropoly-acid of the formula H.sub.k.X.Y.sub.m.Z.sub.12-m.O.sub.40.nH.sub.2 O, wherein X is a hetero-atom selected from the group consisting of P, Si, Ge and As, each of Y and Z is a polyatom selected from the group consisting of W, Mo and V, k is 3 or 4, m is 0 or 1, and n is a positive number.

A two-step process for the oligomerization and hydration of a mixed butenes feed is provided and is implemented in a two-stage system. The two-step process yields a product consisting of diisobutenes (DIBs) and mixed butanols. The DIBs are produced via the selective oligomerization of isobutene in a first stage and the mixed butanols are produced via the hydration, in a second stage, of mixed butenes that remain unreacted in the first stage.

The invention provides a process for producing a variety renewable aromatic compounds such as benzene, toluene, xylenes, and cumene, as well as compounds derived from these including, for example, aniline, benzoic acid, cresol, cyclohexane, cyclohexanone, phenol and bisphenol A, toluene di-isocyanate, isophthalic acid, phthalic anhydride, terephthalic acid and dimethyl terephthalate. The invention also provides for renewable forms of these aromatic compounds.

The present invention produces Cyclic Compound (1) in which organic ring groups including cyclohexane rings and benzene rings are continuously bonded, using a compound having at least one cyclohexane ring and benzene rings with halogen atoms at the two terminuses, in the presence of a nickel compound (bis(1,5-cyclooctadiene)nickel, etc.). Thereafter, by converting the cyclohexane rings in Cyclic Compound (1) into benzene rings, a desired carbon nanoring can be obtained. Thereby, the present invention efficiently produces a carbon nanoring made of a compound having a cyclic structure in which a desired number of organic ring groups are continuously bonded, with a short production process.
