D.  [Catalytic Hydrocondensation of Carbon Monoxide With Olefins.  VI.  Hydrocondensation of Carbon Monoxide With n-Butylene.]  Izvest. Akad. Nauk S.S.S.R., Otdel. Khim.

       Experiments were carried out on equimolecular mixture of H₂ and C₄H₈+2.6-6% of CO, under the same conditions as previously.  At 2.6% CO 100% of CO and 97.1% of C₄H₈ react, at 6% CO, 100%, and 70.4% respectively.  30-35% of the C₄H₈ is reduced to C₄H₁₀.  Liquid products, >C₄, have b. p. 28°-276° C, and consist of aliphatic hydrocarbons, unsaturates 28%.  After hydrogenation liquid condensate was fractionated; analysis (Raman spectra) showed 24% C₅ (about half of which is isopentane), 15% C₆, 8% C₇, 8% C₈, 9% C₉, as well as higher hydrocarbons.
