Abstract
Higher alcohols, esters, and other condensation products are produced from oxygen derivatives of paraffin hydrocarbons (other than ethyl alcohol and mixtures of ethyl and methyl alcohols) and hydrogen (but without carbon monoxide) by the action of a mixed catalyst consisting of one or more of the following feebly basic oxides, viz., alumina, uranium oxide and thoria, in admixture with copper, silver, nickel or chromium or a mixture thereof, preferably in quantity not exceeding 10 per cent, and if desired with the addition of a basic oxide such as calcium, barium, strontium, magnesium or lithium oxides. The quantity of the basic oxide is preferably less than half the catalyst except when the initial oxygen materials contain a substantial proportion of a higher alcohol such as butyl alcohol, when it is preferable to employ a larger proportion. The temperature may be 150-400 DEG C. and the pressure from atmospheric to but not exceeding 50 atmospheres. For the production of high yields of higher alcohols the proportion of the hydrogenating metal should be reduced, but for high yields of higher esters the proportion of hydrogenating metal is increased. In examples (1) to (3) butaldehyde and hydrogen are passed through an electrically heated aluminium tube containing a catalyst containing 100 parts alumina, 6 parts lime, baryta or magnesia, and 1.5 parts copper, the products being butyl acetate and butyrate, butyl alcohol and higher alcohols; (4) a mixture of methyl and butyl alcohols and hydrogen is passed over a catalyst consisting of 89 parts of magnesia, 8 parts of alumina and 3 parts of copper at 350 DEG C. and 30 atmospheres pressure, the products being methyl ethyl carbin-carbinol, hexyl, heptyl and higher alcohols; (5) as in (4) but replacing methyl by ethyl alcohol, the products being hexyl, octyl and higher alcohols, including decyl alcohol, and higher ethers. Specifications 254,819, 337,014, [both in Class 2 (iii), Dyes &c.], and 364,134 are referred to.
