Title: Separating n-propyl alcohol from secondary butyl alcohol by extractive distillation
IPC: C07C29/84
Filed: 1951-05-15
Abstract: n-Propyl alcohol is separated from a mixture containing it and secondary butyl alcohol, by submitting the mixture to extractive distillation using diethyl benzene as auxiliary liquid, whereby n-propyl alcohol is obtained as overhead product, while the bottoms contain the secondary butyl alcohol in admixture with diethyl benzene.  Between 4 to 10 volumes of diethyl benzene are fed to the fractionating column for each volume of alcohol mixture fed thereto; and a reflux ratio between 3 : 1 and 10 : 1 is employed.  The process may be used for separating n-propyl alcohol from a crude fraction of the products obtained by oxidizing butane or a mixture of propane and butane.  In an example a mixture containing 52 per cent by weight of n-propyl alcohol and 9 per cent by weight of secondary butyl alcohol, the remainder being substantially n- and isobutyl alcohols but also some acetal and carbonyl compounds, was fed continuously to the 5th plate from the base of a 30-plate column.  A commercial mixture of the isomeric diethyl benzenes was fed to the 15th plate from the base of the column.  The base and head of the column were maintained at 268 DEG  and 208 DEG F respectively; and a reflux ratio of 5:1 was employed. The n-propyl alcohol withdrawn overhead contained only 1.27 per cent of secondary butyl alcohol, and amounted to 85.3 per cent of the n-propyl alcohol in the feed.

Abstract: 745,723. Submarine hull construction; aircraft framework. PALLEMAERTS, J. E. H. Aug. 19, 1952 [May 19, 1951], No. 11751/61. Classes 4 and 113. [Also in Groups XIII and XXI] A hollow structure, subjected to extreme differences of pressure between the inside and outside, e.g. a submarine hull or aircraft fuselage, is built up of a plurality of laminae L and the successive spaces between the laminae contain a fluid TF which is subjected to such pressures that the difference in pressure acting on the two sides of any lamina is of an amount that can be withstood by the said lamina within safety limits. For example, for a structure to withstand an external pressure of 500 lbs. per sq. inch, the external pressure which each lamina can safely withstand being 100 lbs. per sq. inch, there would be four differential pressure stages with pressures of 400, 300, 200 and 100 lbs. per sq. inch in the spaces between the successive laminµ. The pressures in the successive spaces are applied automatically by adjustable pressure regulators DPT. The laminae are welded to a stepped centre keel beam CKB, a polar rib PR, and to ribs T having steps JR. The upper rib PR may be shaped to house a circular ring bolster provided with a removable cover or hatch which may be laminated and independently pressure-graded in its interlaminar spaces by means of individual pressure regulators. A window (Fig. 6) comprises quartz or acrylic plastic discs 31 assembled in a mount 28. The spaces between the dises 31 contain an optical transmission fluid TF and have their pressure controlled by means of a regulator DPT. As shown in Fig. 4, the ribs T may have expansion and contraction compensating means comprising a band EC, the two parts 11 of which are attached at their tops by pivots 17, 18 to the top rib PR and at their bottoms to pistons 9 whose movement is controlled by a high pressure regulator HPT.
