Title: Process for the joint production of urea and 1-2 alkane diols
IPC: C07C239/00
Filed: 1973-04-13
Abstract: 1414820 Production of urea and 1-2 alkane diols; alkylene carbonates; alkyl 2-hydroxy urethanes SELIAS OF AMERICA (NEDERLAND) NV 13 April 1973 [13 April 1972 11 Aug 1972] 17952/73 Heading C2C Urea is prepared by the reaction of carbon dioxide with an alkylene oxide at 0‹ to 300‹ C. and between 1 and 300 atmospheres and the further reaction of the alkylene carbonate obtained with gaseous ammonia at 0‹ to 300‹ C. and between 1 and 300 atmospheres. The first stage is preferably carried out with an excess of carbon dioxide and the second with an excess of ammonia. The second stage can be performed in two steps; the formation of an alkyl 2-hydroxy urethane by reaction of the alkylene carbonate with one molecule of ammonia and the second step being the reaction of the urethane with a further molecule of ammonia to form urea and the corresponding 1,2-alkane-diol. Basic catalysts, e.g. sodamide, alkali metal alcoholates or amines may be used in the first stage and optionally in the subsequent stage or stages. An oxide of metals from Group II of the Periodic Classification, e.g. MgO may be used as catalyst for the conversion of the urethane to urea and alkane diol. The urea and alkane diol can be separated by distillation under reduced pressure or by selective solution in a solvent, e.g. acetone. The process can be operated batchwise or continuously using the plant illustrated by the diagram. Alkylene oxide (e.g. ethylene oxide or propylene oxide) reacts with carbon dioxide, under pressure in vessel 1 forming alkylene carbonate. Excess carbon dioxide is vented off at 7 and recycled. The alkylene carbonate is distilled under reduced pressure in column 9 and then passes to reactor 11 in which the alkylene carbonate flows countercurrently to ammonia with the formation of alkyl Z-hydroxy urethane; excess ammonia being recycled. In the third reactor 13, the urethane flows countercurrent to ammonia and conversion to urea and the alkane diol occurs. The mixture of solid urea and liquid diol is separated by means of rotary filters 17 and 19, the intervening stirred vessel 18 being used for washing the urea with, e.g. acetone. The diol is separated from the wash liquid by distillation in columns 20 and 21. If a catalyst is used for the'second and third stages, or only for the third stage, it is separated and recycled (hatched line).

Abstract: 790,701. Toy railway track. METTOY CO., Ltd. June 28, 1956 [June 30, 1955], No. 18922/55. Class 132(3) Toy rail track sections particularly suitable for electrically operated toy railways comprise a moulded base of yielding non- metallic material, preferably polyethylene. In Figs. 1, 2, the base includes longitudinal portions 10 each formed with a shallow longitudinal groove 13 into which flanges 21 of an inverted U-section rails are fitted and are secured by chair simulating projections 14. The base also consists of sleeper portions 11 on which the projections are formed. The rails are further located and secured by means of projection 22 on the flanges, which engage in recesses 15 provided between each pair of chair projections 14. The rails are connected by members 30 each consisting of a metal strip bent to inverted U-section and formed with two pairs of depending tongues 31 which are inserted in the two recesses 15 lying nearest the end of the track section. By sliding the rail partially over the connector, the connector is secured in position frictionally tight within the rail and ready to engage the end of the rail of the adjacent section of track. In Fig. 5, a modified connector includes tongues 33 which rest on the upper surface of a sleeper portion 11 and engage on opposite sides of a pair of chair projections 14, the rail flanges 21 holding the tongues against the base. In a further modification, Figs. 8, 9 (not shown), a connector is formed by cutting away the flanges of the end portion of the rail, and reducing the height and width as by pressing of the remaining U-section part. The connectors may be embossed with ribs or they may be formed of solid strip. The conductors may be dispensed with, the rails being merely butted together at some point on the base. If electrical connection between the rails is required, a flat metal strip may be laid in the rail groove in 'the base, both rails then being slidden over the strip and pressing resiliently against it. The longitudinal members of the base may be of reduced thickness for ready cutting or breaking away to allow the track to be bent into a curve. The base may be recessed on its underside or formed as a continuous strip whose upper surface is recessed between the sleepers, the recessed portions being coloured to represent ballast. The longitudinal grooves 13 and the recesses 15 may be omitted. Alternatively the recesses may be deepened to form holes passing through the base. Longitudinal movement of the rails may be prevented by means of sheet metal clips of H-shape, the cross bar of a clip lying below a longitudinal portion of the base and the legs of the clip being bent up on opposite sides of a sleeper portion for turning inwardly over the flanges of the rail. The rails may be solid extruded rods and means may be provided for directly connecting together the base portions of adjacent 'track sections.
