Title: Esterification using azeotropic distillation
IPC: B01D3/36
Filed: 1948-03-05
Abstract: Relatively non-volatile esters, e.g. esters of phthalic, maleic and malonic acids, are produced by boiling an alcohol with a carboxylic acid or anhydride or partial ester in a reaction zone and in the presence of an auxiliary liquid which <PICT:0645218/III/1> forms a ternary azeotrope with water and the alcohol, passing the vapours from the reaction zone into the side, preferably at about mid-point, of a fractionating column which has a reboiler at its base, and passing the liquid which collects at the base of the column to the reaction zone.  Suitable auxiliary liquids are benzene, toluene, xylenes, diallyl ether, and dimethallyl ether. In an example, a mixture comprising mono-allyl phthalate, allyl alcohol, diallyl ether, and sulphuric acid as catalyst, is supplied through line 3 into reaction vessel 1 which is maintained at a temperature of about 110 DEG  C. to 160 DEG  C. by heating-coil 2. The vapours evolved are passed into the side of fractionating column 5, the base of which is maintained at 90 DEG  C. by heating-coil 12.  The vapours leaving the head of the column are condensed; and the condensate is passed to separator 9 where two phases are formed.  The upper layer which predominately comprises allyl alcohol and diallyl ether, is returned to the column through line 10; while the predominately aqueous layer is withdrawn from the system through line 11.  The water-free mixture of allyl alcohol and diallyl ether which collects at the base of the column is passed to vessel 1 through line 13.  The finished ester, diallyl phthalate, is continuously withdrawn from vessel 1 by line 14.

Abstract: 659,918. Casting processes ; moulds. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. March 17, 1949, No. 7360. [Class 83 (i)] In a method of casting metal objects, the mould is formed with recesses or bores so disposed in relation to the casting cavity that by blowing cool air through the bores after preheating the mould, a temperature gradient is produced in the casting to cause progressive freezing of the metal in a desired direction. A refractory mould 1 having a cavity 2 for casting a bar of rectangular cross-section and fed from a gate 3 is formed with a bore on each side of the cavity, the bores following the line 6a of Fig. 1. In operation the mould is preheated to 1000 ‹ C., and cooling air then discharged into the bores from a pipe 6 for about five minutes before casting. The temperature gradient thus set up in the mould ensures progressive freezing of the metal from the end opposite the gate 3. For casting a forked member 11, 12, Fig. 4, molten metal would be supplied by feeders 13 and 14 and the casting locally cooled at intermediate points by means of air cooling recesses 15, 16 formed in the mould. Fig. 5 shows the disposition of an air channel 23 in relation to a turbine blade casting 20. A mould for casting a row of turbine blades 26, Fig. 7, is provided with air cooling releases 29 adjacent the tips of the blade cavities and with thermite-burning recesses 28 near the root portions.
